These are the user uploaded subtitles that are being translated: 1 00:00:25,860 --> 00:00:28,527 Compression and extension springs... 2 00:00:32,066 --> 00:00:33,966 ...Micro drill bits... 3 00:00:38,406 --> 00:00:39,671 ...Skiffs... 4 00:00:43,644 --> 00:00:46,345 ...And painted glass backsplashes. 5 00:00:53,888 --> 00:00:56,889 coiled wire springs are designed to change shape 6 00:00:56,891 --> 00:00:59,324 when weight is added or removed. 7 00:00:59,326 --> 00:01:01,627 Some coils, such as compression springs, 8 00:01:01,629 --> 00:01:04,063 are made to keep components apart. 9 00:01:04,065 --> 00:01:06,865 Other types of coils, like extension springs, 10 00:01:06,867 --> 00:01:10,936 hold things together while the spring expands and contracts. 11 00:01:14,442 --> 00:01:17,142 when a load is applied to a compression spring, 12 00:01:17,144 --> 00:01:21,447 it contracts, while an extension spring expands when pulled. 13 00:01:23,451 --> 00:01:25,284 Compression and extension springs 14 00:01:25,286 --> 00:01:27,486 are made from steel wire. 15 00:01:27,488 --> 00:01:30,422 The diameter and qualities of the wire varies, 16 00:01:30,424 --> 00:01:33,492 depending on the use of the spring. 17 00:01:33,494 --> 00:01:37,029 Spooled onto a reel, the wire uncoils, 18 00:01:37,031 --> 00:01:40,699 pulled by rollers, which lead to a forming machine. 19 00:01:40,701 --> 00:01:44,436 Guide rollers steer the wire, as does this aperture. 20 00:01:46,740 --> 00:01:48,874 Multiple feed rollers push the wire 21 00:01:48,876 --> 00:01:52,678 towards computerized forming tools. 22 00:01:52,680 --> 00:01:56,014 The rollers pause, while the tools do their work, 23 00:01:56,016 --> 00:02:00,552 and then resume to supply wire for the next spring. 24 00:02:00,554 --> 00:02:04,389 Meanwhile, other rollers push the wire around a mandrel, 25 00:02:04,391 --> 00:02:07,459 where it's coiled into an extension spring. 26 00:02:07,461 --> 00:02:09,895 A side-arm controls the diameter, 27 00:02:09,897 --> 00:02:13,465 while another tool cuts it to length. 28 00:02:13,467 --> 00:02:16,969 The forming process has caused internal stresses. 29 00:02:16,971 --> 00:02:22,574 To remove those stresses, the springs are heat-treated. 30 00:02:22,576 --> 00:02:24,810 As the springs move out of the oven, 31 00:02:24,812 --> 00:02:27,045 they travel through a cooling chamber. 32 00:02:27,047 --> 00:02:29,047 The heating and controlled cooling 33 00:02:29,049 --> 00:02:31,183 improves the physical properties, 34 00:02:31,185 --> 00:02:35,354 allowing the springs to withstand repeated compression. 35 00:02:35,356 --> 00:02:37,556 With internal stresses relieved, 36 00:02:37,558 --> 00:02:42,161 it's time to work on the outer surface of the steel springs. 37 00:02:42,163 --> 00:02:44,897 A rack conveyer dips extension springs 38 00:02:44,899 --> 00:02:47,299 into a vat of water-based paint. 39 00:02:49,336 --> 00:02:52,171 The paint seeps into the crevices of the coils, 40 00:02:52,173 --> 00:02:54,373 providing even paint coverage. 41 00:02:57,745 --> 00:03:00,779 then the rack conveyer takes the painted springs 42 00:03:00,781 --> 00:03:03,448 on a ten-minute loop through an oven. 43 00:03:03,450 --> 00:03:06,251 This step bakes the paint onto the steel, 44 00:03:06,253 --> 00:03:09,421 providing a corrosion-resistant finish. 45 00:03:09,423 --> 00:03:14,226 This is what the springs look like before and after painting. 46 00:03:14,228 --> 00:03:17,496 These truck suspension springs are made differently. 47 00:03:21,101 --> 00:03:24,770 a machinist heats the end of a steel rod in a furnace, 48 00:03:24,772 --> 00:03:28,207 inserting it between forming tools to taper it. 49 00:03:28,209 --> 00:03:32,077 This taper will allow the completed spring to sit upright. 50 00:03:34,281 --> 00:03:39,718 Next, the entire rod goes into a 1,796-degree furnace. 51 00:03:41,322 --> 00:03:43,989 Once the rod in red-hot and malleable, 52 00:03:43,991 --> 00:03:45,424 it exits the furnace 53 00:03:45,426 --> 00:03:48,594 and is transferred to the forming mandrel. 54 00:03:48,596 --> 00:03:52,497 The mandrel spins to wind the soft, steel wire, 55 00:03:52,499 --> 00:03:56,101 transforming the straight steel rod into a spring. 56 00:03:59,139 --> 00:04:04,042 the spring is placed in a bucket and lifted to an oil bath. 57 00:04:04,044 --> 00:04:06,878 The bath quenches and hardens the steel. 58 00:04:10,217 --> 00:04:13,051 then the spring travels through a furnace. 59 00:04:13,053 --> 00:04:15,921 The heat burns off quenching oil residue. 60 00:04:18,459 --> 00:04:21,159 A technician inserts the compression springs 61 00:04:21,161 --> 00:04:22,861 in a revolving fixture, 62 00:04:22,863 --> 00:04:27,099 allowing the ends of the springs to extend outward. 63 00:04:27,101 --> 00:04:30,836 As the fixture revolves, grinding wheels remove material 64 00:04:30,838 --> 00:04:33,405 to flatten the exposed ends. 65 00:04:33,407 --> 00:04:36,208 This flattened profile is another way to ensure 66 00:04:36,210 --> 00:04:38,510 that the springs will sit upright. 67 00:04:40,381 --> 00:04:41,580 Once complete, 68 00:04:41,582 --> 00:04:44,216 the technician measures the height of the spring 69 00:04:44,218 --> 00:04:46,551 to confirm that the correct amount of material 70 00:04:46,553 --> 00:04:49,288 has been ground off. 71 00:04:49,290 --> 00:04:52,257 The grinding has made a substantial difference. 72 00:04:55,162 --> 00:04:58,363 The next machine removes surface flaws. 73 00:04:58,365 --> 00:05:02,034 An operator places the spring inside the machine. 74 00:05:04,004 --> 00:05:05,704 As the spring spins, 75 00:05:05,706 --> 00:05:09,941 a fine, abrasive steel shot sands away imperfections. 76 00:05:11,979 --> 00:05:14,579 You can see the difference this step makes in the spring 77 00:05:14,581 --> 00:05:15,714 on the right. 78 00:05:18,185 --> 00:05:22,554 The exposure to heat has made the steel wire more flexible. 79 00:05:22,556 --> 00:05:25,490 A technician places the wire in a press machine 80 00:05:25,492 --> 00:05:27,526 and sets the compression and height. 81 00:05:29,229 --> 00:05:31,396 The press squeezes the coils 82 00:05:31,398 --> 00:05:34,499 until the desired amount of compression is achieved. 83 00:05:36,203 --> 00:05:38,170 After the spring has been painted, 84 00:05:38,172 --> 00:05:40,372 the company name and model information 85 00:05:40,374 --> 00:05:44,042 is stamped onto the springs. 86 00:05:44,044 --> 00:05:46,812 It takes two hours to make a spring, 87 00:05:46,814 --> 00:05:50,349 and now it's finally ready for some flex time. 88 00:06:06,467 --> 00:06:09,568 narrator: Thousands of years ago, our earliest ancestors 89 00:06:09,570 --> 00:06:11,536 might have picked up a pointed rock 90 00:06:11,538 --> 00:06:14,473 and spun it between their hands to bore a hole 91 00:06:14,475 --> 00:06:16,875 in something they wanted to modify. 92 00:06:16,877 --> 00:06:20,912 Today, you can buy drill bits in all shapes and sizes. 93 00:06:25,886 --> 00:06:29,054 Drill bits are often associated with carpentry, 94 00:06:29,056 --> 00:06:31,590 but from electronics to surgery tooling, 95 00:06:31,592 --> 00:06:33,058 there are all kinds of fields 96 00:06:33,060 --> 00:06:38,063 that require ultra-thin, high-performance drill bits. 97 00:06:38,065 --> 00:06:40,298 The production process begins with lengths 98 00:06:40,300 --> 00:06:43,635 of 100% carbide called blanks. 99 00:06:47,574 --> 00:06:48,940 a diamond grinding wheel 100 00:06:48,942 --> 00:06:52,010 lubricated with a specialized cutting liquid 101 00:06:52,012 --> 00:06:55,814 is applied to a chamfered edge on one tip of the blank. 102 00:06:58,385 --> 00:07:00,552 This step removes the rough edges left 103 00:07:00,554 --> 00:07:02,954 when the blanks were cut down to size. 104 00:07:06,427 --> 00:07:12,197 a vibrating device organizes the blanks inside a rotating bowl. 105 00:07:12,199 --> 00:07:15,801 The vibrating action shifts the blanks into single file 106 00:07:15,803 --> 00:07:18,870 so they can proceed one-by-one to the next step. 107 00:07:20,974 --> 00:07:24,376 This machine is called a centerless grinder. 108 00:07:24,378 --> 00:07:27,579 The blanks move between two rotating drums, 109 00:07:27,581 --> 00:07:30,749 which grinds them down to a specified length. 110 00:07:35,456 --> 00:07:37,456 the blanks pour out of the machine 111 00:07:37,458 --> 00:07:40,192 immersed in the lubricating fluid. 112 00:07:40,194 --> 00:07:42,828 An operator selects one and places it 113 00:07:42,830 --> 00:07:45,230 in a quality control gauge to check 114 00:07:45,232 --> 00:07:48,700 that it meets the manufacturer's required tolerances. 115 00:07:54,475 --> 00:07:57,642 the blanks now enter a cnc rollomatic. 116 00:07:59,580 --> 00:08:03,748 An operator sets up the tool and programs its work process. 117 00:08:06,019 --> 00:08:09,421 A robotic auto-feeder picks up the blanks one-by-one 118 00:08:09,423 --> 00:08:11,323 from a specialized palette. 119 00:08:13,360 --> 00:08:16,027 The robotic arms places each blank carefully 120 00:08:16,029 --> 00:08:19,664 and precisely in a waiting chuck, or collar, 121 00:08:19,666 --> 00:08:22,067 and then moves them back into position. 122 00:08:24,505 --> 00:08:28,373 The tool moves forward, holding the blank perfectly still 123 00:08:28,375 --> 00:08:30,542 as a pair of wheels close in. 124 00:08:32,279 --> 00:08:34,846 Liquid coolant pours over the blank 125 00:08:34,848 --> 00:08:37,015 as the wheels precision pinch-grind 126 00:08:37,017 --> 00:08:38,717 the tip of the blank, 127 00:08:38,719 --> 00:08:41,820 grinding it down to about 1/10 of a millimeter -- 128 00:08:41,822 --> 00:08:43,922 the width of a human hair. 129 00:08:43,924 --> 00:08:46,091 It's a delicate process. 130 00:08:46,093 --> 00:08:49,528 The rollomatic produces 48 pieces per hour. 131 00:08:52,032 --> 00:08:58,303 Next, a technician places small sheets of plastic foil in a jig. 132 00:08:58,305 --> 00:09:00,105 The foil is shim stock, 133 00:09:00,107 --> 00:09:02,908 color-coded according to its thickness. 134 00:09:02,910 --> 00:09:06,945 The jig raises the metal support to a specified height. 135 00:09:06,947 --> 00:09:09,447 When the blank advances over the support, 136 00:09:09,449 --> 00:09:11,483 a mark left in the blue ink determines 137 00:09:11,485 --> 00:09:13,552 whether the metal blank is centered. 138 00:09:15,756 --> 00:09:19,224 Once complete, a technician uses a magnifying tool 139 00:09:19,226 --> 00:09:21,593 to fine-tune the placement of the blank 140 00:09:21,595 --> 00:09:24,696 and ensure that it's perfectly centered. 141 00:09:24,698 --> 00:09:28,199 This process can take four to five hours. 142 00:09:30,203 --> 00:09:33,805 The blank is finally ready for the crucial fluting process 143 00:09:33,807 --> 00:09:37,375 that will transform it from a cylindrical length of carbide 144 00:09:37,377 --> 00:09:41,246 with a narrow tip into a micro drill bit. 145 00:09:41,248 --> 00:09:43,214 After hours of preparation, 146 00:09:43,216 --> 00:09:46,685 this operation takes just a few seconds. 147 00:09:46,687 --> 00:09:49,087 An industrial grinding diamond wheel 148 00:09:49,089 --> 00:09:53,124 has sliced a microscopic groove at a precise angle. 149 00:09:53,126 --> 00:09:56,361 The technician inserts the bit, sharp-end first, 150 00:09:56,363 --> 00:09:59,197 into a precision machining device. 151 00:09:59,199 --> 00:10:01,600 A steel bushing with a brass insert 152 00:10:01,602 --> 00:10:03,969 holds the tip of the bit in place 153 00:10:03,971 --> 00:10:06,938 as a cutting wheel slices an angled point. 154 00:10:10,777 --> 00:10:14,212 it's impossible to see the difference between a bit before 155 00:10:14,214 --> 00:10:16,648 and after fluting. 156 00:10:16,650 --> 00:10:19,751 Using a magnifying device, the technician conducts 157 00:10:19,753 --> 00:10:22,520 a quality control check of the bit. 158 00:10:22,522 --> 00:10:25,523 As the screen reveals the finely-cut flute, 159 00:10:25,525 --> 00:10:28,526 the technician ensures the tool's parameters meet 160 00:10:28,528 --> 00:10:30,829 manufacturing standards. 161 00:10:30,831 --> 00:10:34,265 Once such parameter has to do with the shape of the flute, 162 00:10:34,267 --> 00:10:36,167 which has a forward taper. 163 00:10:36,169 --> 00:10:38,937 This means the flue groove becomes shallower 164 00:10:38,939 --> 00:10:43,174 from tip to base at a very precise angle. 165 00:10:43,176 --> 00:10:46,578 This feature simultaneously strengthens the tool 166 00:10:46,580 --> 00:10:51,149 while increasing the chip flow along the groove. 167 00:10:51,151 --> 00:10:54,019 Although carbide is incredibly strong, 168 00:10:54,021 --> 00:10:56,454 when it's milled to the thickness of a human hair, 169 00:10:56,456 --> 00:10:58,023 it becomes fragile. 170 00:10:58,025 --> 00:10:59,357 Needless to say, 171 00:10:59,359 --> 00:11:02,627 careful packaging is extremely important. 172 00:11:15,075 --> 00:11:17,475 narrator: A skiff is a lightweight motorboat 173 00:11:17,477 --> 00:11:20,045 designed for use on shallow water. 174 00:11:20,047 --> 00:11:23,014 Unlike most boats that have a v-shaped hull, 175 00:11:23,016 --> 00:11:25,583 a skiff's hull is relatively flat, 176 00:11:25,585 --> 00:11:28,386 allowing it to sit high above the water. 177 00:11:35,128 --> 00:11:37,996 This type of boat is known as a poling skiff. 178 00:11:37,998 --> 00:11:41,299 It's designed with a platform set over the engine, 179 00:11:41,301 --> 00:11:44,335 which provides fishermen a ledge to stand on 180 00:11:44,337 --> 00:11:48,039 while moving the boat along with a pole. 181 00:11:48,041 --> 00:11:50,408 A technician cleans the hull mold 182 00:11:50,410 --> 00:11:52,644 and coats it with a release agent, 183 00:11:52,646 --> 00:11:55,413 then sprays on a gel coating. 184 00:11:55,415 --> 00:12:00,051 The gel coating forms the glossy outer layer of the boat. 185 00:12:00,053 --> 00:12:03,722 Then the technician measures the gel coat layer with a mill gauge 186 00:12:03,724 --> 00:12:06,057 and leaves it to harden for about an hour. 187 00:12:08,228 --> 00:12:11,830 Computer-guided machines cut pieces for the hull, deck, 188 00:12:11,832 --> 00:12:14,966 and cockpit floor from four different materials -- 189 00:12:14,968 --> 00:12:19,804 woven fiberglass mat, rigid pvc sheet-foam, kevlar -- 190 00:12:19,806 --> 00:12:22,607 a high-strength, heat-resistant synthetic fabric -- 191 00:12:22,609 --> 00:12:27,145 and stiffer kevlar reinforced with carbon fiber. 192 00:12:27,147 --> 00:12:30,014 Chopped fiberglass saturated with resin 193 00:12:30,016 --> 00:12:33,118 is applied onto the gel coat. 194 00:12:33,120 --> 00:12:36,087 With spray-glue, a technician adheres a layer 195 00:12:36,089 --> 00:12:39,891 of carbon kevlar, fiberglass, foam, 196 00:12:39,893 --> 00:12:42,961 and a second layer of kevlar to the base. 197 00:12:42,963 --> 00:12:46,464 These layered materials create a mold for the boat's deck 198 00:12:46,466 --> 00:12:48,466 and cockpit floor. 199 00:12:48,468 --> 00:12:51,369 The flat squares are aluminum-retention plates, 200 00:12:51,371 --> 00:12:54,272 where components will be screwed down. 201 00:12:54,274 --> 00:12:56,841 Raised squares are where openings will be cut out 202 00:12:56,843 --> 00:12:59,711 for storage compartments. 203 00:12:59,713 --> 00:13:02,747 Each mold is bagged and connected with hoses 204 00:13:02,749 --> 00:13:05,283 to a vacuum-infusion system. 205 00:13:05,285 --> 00:13:09,854 The vacuum compresses the layers to 2/3 their original thickness, 206 00:13:09,856 --> 00:13:12,223 then the system draws a specialized resin 207 00:13:12,225 --> 00:13:13,658 through the materials, 208 00:13:13,660 --> 00:13:16,261 which will bond them into a single unit. 209 00:13:16,263 --> 00:13:18,830 The system removes all excess resin 210 00:13:18,832 --> 00:13:21,366 so that the ratio of resin to materials 211 00:13:21,368 --> 00:13:24,202 creates maximum strength with minimal weight. 212 00:13:26,239 --> 00:13:29,641 Next, another technician assembles the boat's wiring 213 00:13:29,643 --> 00:13:32,443 into a unit known as a wiring harness. 214 00:13:32,445 --> 00:13:35,780 He winds the individual wires around a schematic 215 00:13:35,782 --> 00:13:38,850 that's custom-designed for this specific boat. 216 00:13:38,852 --> 00:13:41,152 He attaches connectors on the ends 217 00:13:41,154 --> 00:13:43,655 that fit into water-tight plugs. 218 00:13:43,657 --> 00:13:48,393 Every wire is labeled for easy identification. 219 00:13:48,395 --> 00:13:50,728 Once the resin has fully cured, 220 00:13:50,730 --> 00:13:54,866 the plastic vacuum bag is removed from each mold. 221 00:13:54,868 --> 00:13:57,802 A technician knocks wedges under the flange that formed 222 00:13:57,804 --> 00:14:01,739 around the perimeter, and thanks to the release agent, 223 00:14:01,741 --> 00:14:05,710 a team can easily lift the flange out of the mold. 224 00:14:05,712 --> 00:14:07,345 The flange is trimmed, 225 00:14:07,347 --> 00:14:10,081 and the openings are cut with a diamond saw, 226 00:14:10,083 --> 00:14:13,284 which leaves clean, straight edges. 227 00:14:13,286 --> 00:14:16,454 Next, a team begins assembling the boat. 228 00:14:16,456 --> 00:14:18,957 First, they apply adhesive to the hull 229 00:14:18,959 --> 00:14:22,460 to prepare the cockpit floor for attachment. 230 00:14:22,462 --> 00:14:26,698 Once the cockpit's in place, white pvc tubes are installed 231 00:14:26,700 --> 00:14:29,334 for storing fishing rods under the deck. 232 00:14:29,336 --> 00:14:32,670 Then the wiring harness is installed. 233 00:14:32,672 --> 00:14:35,874 The aluminum fuel tank is mounted in the bow. 234 00:14:35,876 --> 00:14:40,311 These components are made of strong, lightweight materials. 235 00:14:40,313 --> 00:14:43,948 A technician places screws into the metal retention plates 236 00:14:43,950 --> 00:14:46,651 that were molded into the structure. 237 00:14:46,653 --> 00:14:50,755 Next, the wiring harness is attached to water-tight plugs 238 00:14:50,757 --> 00:14:54,025 connected to the electrically-powered components. 239 00:14:54,027 --> 00:14:55,827 After installing plumbing lines 240 00:14:55,829 --> 00:14:58,463 for the aerated live bait compartment, 241 00:14:58,465 --> 00:15:02,667 team members glue the deck to the hull. 242 00:15:02,669 --> 00:15:05,937 The lids are installed for the deck openings. 243 00:15:05,939 --> 00:15:08,506 This one covers the forward storage compartment 244 00:15:08,508 --> 00:15:12,377 containing the fuel tank and the tubes for the fishing rods. 245 00:15:16,850 --> 00:15:19,617 next, the console helm is assembled, 246 00:15:19,619 --> 00:15:23,655 which is the nautical equivalent of a vehicle dashboard. 247 00:15:23,657 --> 00:15:27,458 Onto the helm, a technician installs the steering wheel, 248 00:15:27,460 --> 00:15:28,860 the engine gauge, 249 00:15:28,862 --> 00:15:30,695 the panel containing the ignition 250 00:15:30,697 --> 00:15:33,364 and switches for electrical components, 251 00:15:33,366 --> 00:15:35,934 and the throttle, which controls speed. 252 00:15:38,638 --> 00:15:41,472 Then, two technicians bolt the outboard motor 253 00:15:41,474 --> 00:15:44,676 onto the engine mount at the stern. 254 00:15:44,678 --> 00:15:46,978 While this skiff is built with a square stern 255 00:15:46,980 --> 00:15:50,648 and pointed bow, its sides are flat. 256 00:15:50,650 --> 00:15:54,018 This enables the boat to move quietly through the water. 257 00:15:56,323 --> 00:16:00,158 Next, technicians mount the poling platform over the engine, 258 00:16:00,160 --> 00:16:02,860 securing it with glue and screws. 259 00:16:07,901 --> 00:16:11,235 finally, a technician installs the finishing touches, 260 00:16:11,237 --> 00:16:13,671 and the skiff is ready for launch. 261 00:16:13,673 --> 00:16:16,274 Due to its low profile and light weight, 262 00:16:16,276 --> 00:16:20,111 this boat can operate in just mere inches of water. 263 00:16:33,226 --> 00:16:36,894 narrator: Painted glass is an un-traditional backsplash choice 264 00:16:36,896 --> 00:16:39,764 specifically designed to look minimalistic. 265 00:16:39,766 --> 00:16:42,667 Due to fewer grout lines, these painted panels 266 00:16:42,669 --> 00:16:46,671 are also easier to clean so that when grease splatters, 267 00:16:46,673 --> 00:16:49,574 the backsplash can be wiped down quickly. 268 00:16:53,713 --> 00:16:55,813 these panels are painted on the back 269 00:16:55,815 --> 00:16:59,017 so the neutral color shows through the front side. 270 00:16:59,019 --> 00:17:00,985 Since glass is reflective, 271 00:17:00,987 --> 00:17:03,755 this backsplash brings both subtle color 272 00:17:03,757 --> 00:17:06,591 and light into the kitchen. 273 00:17:06,593 --> 00:17:10,061 Production starts with an automated loading system. 274 00:17:10,063 --> 00:17:12,230 Suctioning grippers transfer the glass 275 00:17:12,232 --> 00:17:14,065 to the rails of a conveyer. 276 00:17:16,436 --> 00:17:18,636 this is low-iron glass, 277 00:17:18,638 --> 00:17:21,572 a kind of glass with a very high clarity. 278 00:17:21,574 --> 00:17:23,775 Once color is applied to the back, 279 00:17:23,777 --> 00:17:26,344 the color will appear more clearly on the front 280 00:17:26,346 --> 00:17:28,713 than regular glass. 281 00:17:28,715 --> 00:17:32,183 For easy identification, a computerized system 282 00:17:32,185 --> 00:17:35,086 applies labels to each of the parts to be cut. 283 00:17:36,956 --> 00:17:40,024 A diamond cutting tool scores the glass, 284 00:17:40,026 --> 00:17:43,361 mapping out backsplash panels and smaller pieces 285 00:17:43,363 --> 00:17:45,496 to be used for showroom samples. 286 00:17:47,734 --> 00:17:51,769 Once complete, rollers move the glass sheet to the next station. 287 00:17:56,209 --> 00:17:59,911 two technicians snap the glass along the score lines. 288 00:18:05,018 --> 00:18:07,485 this snapping action creates clean cuts, 289 00:18:07,487 --> 00:18:09,787 preventing the glass from shattering. 290 00:18:12,292 --> 00:18:15,827 The snap action doesn't work for cuts within the panel. 291 00:18:15,829 --> 00:18:19,964 Instead, a highly pressurized water jet mixed with garnet grit 292 00:18:19,966 --> 00:18:22,200 cuts through the glass. 293 00:18:22,202 --> 00:18:25,670 The cutting device makes holes for electrical switch plates 294 00:18:25,672 --> 00:18:28,306 and for mounting hardware. 295 00:18:28,308 --> 00:18:29,674 With the cutting done, 296 00:18:29,676 --> 00:18:32,176 a technician rinses the residual grit. 297 00:18:34,247 --> 00:18:35,980 The sharp edges are profiled 298 00:18:35,982 --> 00:18:38,783 so the glass will be safer to handle. 299 00:18:38,785 --> 00:18:41,018 As this display model demonstrates, 300 00:18:41,020 --> 00:18:44,055 there are several choices. 301 00:18:44,057 --> 00:18:47,592 Next, an operator loads the glass backsplash 302 00:18:47,594 --> 00:18:49,227 into a slotted conveyer, 303 00:18:49,229 --> 00:18:52,163 which transfers it to the edging machine. 304 00:18:52,165 --> 00:18:53,865 Underneath the edging machine, 305 00:18:53,867 --> 00:18:57,001 there are a series of grinding and buffing wheels. 306 00:18:57,003 --> 00:18:59,570 As the glass travels over the wheels, 307 00:18:59,572 --> 00:19:01,939 the edge of the glass will transform. 308 00:19:03,676 --> 00:19:07,044 Once the machine is activated, the wheels spin, 309 00:19:07,046 --> 00:19:10,248 while lubricant flows over the glass. 310 00:19:10,250 --> 00:19:13,551 The wheels profile and buff the edge of the glass 311 00:19:13,553 --> 00:19:16,087 that will be the top of the backsplash. 312 00:19:18,525 --> 00:19:21,492 Next, the operator examines the edge to confirm 313 00:19:21,494 --> 00:19:23,060 that it's been contoured 314 00:19:23,062 --> 00:19:25,363 and that there aren't any imperfections. 315 00:19:27,433 --> 00:19:30,601 Apart from making the glass safer to handle, 316 00:19:30,603 --> 00:19:33,271 the profiled edge will reduce the possibility 317 00:19:33,273 --> 00:19:36,440 of chipping and breakage. 318 00:19:36,442 --> 00:19:37,742 At the next station, 319 00:19:37,744 --> 00:19:41,846 spinning brushes with soft bristles scrub the panel. 320 00:19:44,384 --> 00:19:47,318 The process removes any dust or polishing grit 321 00:19:47,320 --> 00:19:50,354 to prepare it for the next steps. 322 00:19:50,356 --> 00:19:52,390 Once out of the washing machine, 323 00:19:52,392 --> 00:19:58,629 the glass backsplash travels through a 1,299-degree oven. 324 00:19:58,631 --> 00:20:01,499 The intense heat followed by a quick cooling 325 00:20:01,501 --> 00:20:04,402 tempers the glass to make it heat resistant. 326 00:20:06,506 --> 00:20:10,274 Roller conveyers transfer the glass to the painting station. 327 00:20:13,313 --> 00:20:16,113 a technician mixes the acrylic paint. 328 00:20:16,115 --> 00:20:19,150 Since paint doesn't stick to glass on its own, 329 00:20:19,152 --> 00:20:21,586 a special adhesion-promoting chemical 330 00:20:21,588 --> 00:20:23,921 is added to the mixture. 331 00:20:23,923 --> 00:20:27,191 The technician mixes the colorants into the white base 332 00:20:27,193 --> 00:20:29,894 according to the formula. 333 00:20:29,896 --> 00:20:32,263 Specific amounts of red and yellow paint 334 00:20:32,265 --> 00:20:34,498 produce a brilliant orange hue. 335 00:20:40,039 --> 00:20:42,240 next, sprayers apply the paint 336 00:20:42,242 --> 00:20:44,642 evenly across the back of the panel 337 00:20:44,644 --> 00:20:47,245 as the glass moves along a conveyer. 338 00:20:50,350 --> 00:20:53,217 then the backsplash enters an infrared oven 339 00:20:53,219 --> 00:20:56,187 heated to 302 degrees fahrenheit. 340 00:20:59,259 --> 00:21:03,060 the painted glass bakes in the oven for about four minutes. 341 00:21:06,466 --> 00:21:09,934 once heating is complete, a technician applies gray paint 342 00:21:09,936 --> 00:21:12,503 over the backside of the backsplash. 343 00:21:12,505 --> 00:21:14,772 This coat won't affect the orange hue, 344 00:21:14,774 --> 00:21:17,241 but it will protect the backsplash from damage 345 00:21:17,243 --> 00:21:19,410 during transport and installation. 346 00:21:21,381 --> 00:21:24,982 Neutral-colored backsplashes make a more subtle statement, 347 00:21:24,984 --> 00:21:26,817 while brightly-colored backsplashes 348 00:21:26,819 --> 00:21:28,486 can make a kitchen pop. 28466
