| The UPC-R shows extraordinary success in ultra-precision spherical and aspheric cutting applications. |
|
 Application : |
1.CD. DVD pickup lenses molding.
2.Molding for optical lenses for cameras.
3.Spherical and aspheric reflecting mirrors for laser and X-ray equipment.
4.Spherical and aspheric lenses.
5.Other precision parts machined with CNC 2-axis lathe
. |
|
| Features : |
1.A tool edge contour of 0.05μm(50nm/0.000002”) is achieved over a wide working angle of 90°.
2.The cutting edge is precisely finished with minimal waviness. The use of SEM at 2000x magnification for
inspection
eliminates chipping on the finished tool edge surface.
