Diamond Maching

Air Bearing
Cutting Head

Diamond Tool Holder

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”).

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.

Lenticular Lens Arrays, Projection Screens : Ultra-Precision Micro Machining / Conturing System 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.
