This piece represents New Tech's laser and conventional machining
capabilities. The tube, with a wall thickness of .005", was cut and the
end cap (A) .005" thick was welded to the tube. The upper flange
assembly (B) was done in the conventional machine shop. This was then
assembled and welded to the tube and a weld to create a hermetic seal
(C) was required. The weld in area C was also critical in that the ID
of the tube had to remain constant. | 
The various size armatures were all fabricated using the laser to cut
and weld the numerous laminations.
| 
Glass-to-metal seals were laser welded without affecting the glass.
| 
This optical baffle was completely fabricated from 304 ST. flat stock
.005" thick. In this case, New Tech laser cut and welded the tube. The
internal baffles were cut then positioned within the tube and completely
welded to the ID of the tube by applying the laser to the circumference of
the OD. It was critical that there be no voids in the weld that would allow
light to pass through. | 
This application is another example of how a customer's problem was
solved by the combination of laser and conventional machining. The problem
was that the bottom surface had to be extremely flat. Conventional machining
would have genereated too much heat causing the bottom to deform. New Tech's
solution was to make the bottom out of two pieces of stock, and cut a hole
in the top section which provided the recess in which the bar stock would be
inserted. The laser welded the two flat pieces to form the bottom and welded
the bar stock into the recess. The bar stock was turned and milled by
conventional machining methods. |
