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.
