Super precise mirror polish
focus
Precision lapping, flat lapping, precision polishing, precision grinding, any other precision manufacturing
Overview
TDC Corporation is a manufacturing company which mainly provide super precise polishing/lapping service.
Our expertise is...precision lapping, precision polishing, precision grinding, any other precision machining.
Our mirror polishing technology make the surface like a mirror, and achieve ultra flatness, parallelism, size tolerance, at the same time.
Characteristic technologies
Precision Polishing/Lapping technique is our core competence.
TDC's lapping technique can achieve not only smooth surface,
but also very precise flatness, parallelism, size tolerance, etc.
Roughness < Ra1nm
Flatness < 0.05um(100diameter)
Parallelism < 0.5um
Size tolerance +/- 0.3um
What we can achieve with lapping technique, other than flat surface.
Curved surface can be polished
Super precise ball (size tolerance +/- 0.2um)
Roll/Pipe polishing
micro cube
Foil (Stainless,Copper,Ti) can be polished with mirror surface.Thickness starts from 0.001mm.

Case Study in innovation
Mirror Fit Spacer - super precision shims / spacers / washers
TDC's super precision shims, spacers, washers enables you super precise assemble.
What is the advantage of TDC's Spacer??
・Thickness starts from 0.001mm.
・You can order from one piece to mass production.
・You can make its surface like a mirror (Mirror Fit Spacer)
note: standard shim/spacer doesn't have mirror surface
・You can order special size or shape.
Difference between Mirror Fit Spacer and Normal Spacer
Mirror Fit Spacer
Roughness:Ra1nm
You can see TDC logo reflecting on the spacers.
Normal spacer
Roughness:Ra70nm
You can't see TDC logo on the surface of spacers.
TDC Standard Shim / Spacer
TDC prepare standard type shim / spacers in stock.

Super precision ball
TDC apply its polishing/lapping technology to manufacture super precision ball. We are challenging to develop further precision ball.
| Size | 0.5mm - 25mm |
| Size tolerance | +/- 0.0005mm |
| Sphericity | 50 nanometer |
| Material | any kinds. (e.g. metals, ceramics...) |
| Note | No scratch on surface ( mirror finished ) |
Super precision ball is used for - Probe - Stylus - Bearing -Master ball for precision measurement instruments other high precision application
Roll polishing,Pipe polishing(inside/outside)
TDC polish roll surface to Ra2 nanometer.
Our polishing technology makes it possible to make its surface roughness super fine, and keep its circularity.
| Size | up to 2500mm L |
| Material | Stainless steel,Titanium,Aluminum,Glass, Electro plating surface(Ni, Cr, Hard Cr) |
micro Cube manufacturing
TDC apply its lapping technique to manufacturing micro Cube.
| Size | 0.05 * 0.05 * 0.05 (mm) |
| Size tolerance | +/- 0.002 (mm) |
| Material | Any kind(Metals, Ceramics, Plastics, Semiconductor material, new material) |
