Example of use in precise mold, Nanoinprint mold, wafer polishing.

e polish super precise mirror rolls for nanoimprint molds.

Inspection and Measurement

Our precise Dimensional control technology is used for Measurement equipment and machine tools.

Stone surface plate does not have high wear resistance so it has to be reworked periodically.
TDC reworks on your used surface plate, or we can also produce a new surface plate.

Semiconductor Manufacturing Equipment

We contributed to cost down and Improvement of the device by manufacturing in high quality.

Use our precise mirror polishing technology to improve the quality for stages.
We will aim for an extreme preciseness in Tolerance, roughness, flatness, parallelism, angle with any material such as metal, ceramics, resin, glass and such.

Automotive Industry

Corresponds to the needs of automotive industry by manufacturing test pieces for R&D, Production of tool and jig.

We create R&D test pieces, tool and jig on request. We can deal with materials such as metal, resin, glass, and semiconductor material.
We can also help you create and improve various prototypes of components in question making use of our polishing techniques.

Electronics Engineering

Useful for electronics fields by polishing crystal materials and wafers.

TDC’s lapping technology not only finishes the surface in high quality roughness, but also can achieve precise flatness and parallelism.
Light-guiding Plate 9
Flatness 1um, Roughness 2nm
Light-guiding Plate 5
Flatness 0.5um, Roughness 1nm

Alternative Energy

Polishing wafers for Alternative energy, also contributing to the efficiency of new device substrates.

We will polish wafers for development of a new device on request.


Aerospace field.

We are capable of manufacturing metal Reflecting mirrors, and improve the surface condition for Capsule inner surface.


Contribute to the development of technology for MEMS

By mirror polishing the surface, we can realize completely non-scratched surface for creating fine and precise patterns.
