The MLA4000 ULTRA PRECISION MICRO MACHINING / CONTOURING SYSTEM
and our post machining replication technology allow the designer freedom to
create new and high quality components. We offer a unique combination of options
for the fabrication of products which include three dimensional optics, forms
and arrays. Click to download complete Diamond Machining Bulletin (.pdf) 

The MLA4000 ULTRA PRECISION MICRO MACHINING/CONTOURING
SYSTEM is pictured above. The pattern being machined into the substrate is a
High Aspect Ratio, Fine Pitch Lenticular Lens Array. The Spindle and Carriage
are Air Bearing supported for maximum optical surface quality of the fabricated
part. Pictured below are the Cutting Head, Diamond Tools, and a closer view
of the substrate being machined on the MLA4000 SYSTEM.

The CUTTING HEAD is a variable speed, 6” diameter air bearing
supported spindle. The Cutting Head Tool Adapter is designed to accommodate
six individual Single Crystal Cutting Diamonds. The Single Crystal Roughing
and Finishing Diamonds are manufactured with the required contours and
mounted in the Cutting Head. By combining up to six different shaped diamonds
in the Cutting Head, complex features can be machined into the substrate.
|
Each Single Crystal contouring diamond is mounted in a
Precision Tool Holder and ground and polished to a very precise contour
and extremely fine finish. Shapes include flats, convex and concave
spherical and parabolic contours, wedges and sharp points in various
geometric configurations. Up to six individual Diamond Contouring Tools
can be mounted on the Air Bearing Cutting Head and aligned so that they
work together to produce the desired part shape.

A pure copper substrate is shown being contoured with
a high aspect ratio lenticular lens array pattern on the MLA4000 System.
The optical quality surface finish of the lens contour reflects the
image of the air supply hose and housing. The MLA4000 has an X-Y machining
capacity of 1.0 X 1.02 meters, (39.37” x 40”). For larger products,
the MLA5400 has an X-Y machining capacity of 1.37 X 1.52 meters. (54”
x 60”). |
