Examples of products produced by TDC’s grinding process

At TDC, we also accept consultations on all kinds of grinding processing with our extensive processing equipment and grinding know-how accumulated over many years.

In addition, TDC combines grinding and polishing processes to achieve ultra-precision manufacturing with its own know-how.

Here, we will introduce an example of a product manufactured by TDC that incorporates grinding.

Stone plate correction processing

Product Description

TDC accepts requests for production and modification of granite surface plates. Depending on the specifications and the condition of the granite surface plate, we combine grinding and lapping to achieve the desired accuracy.

After the surface is polished by grinding, final polishing is performed by lapping.

Accuracy

200×200 flatness 0.5um guaranteed

300×300 flatness 1um guaranteed

For details, please see the page of “Maintenance of surface plate“.

YAG ceramic precision mirror plate

Product Description

We produced a precision mirror plate by combining cutting by cutting, grinding, and mirror polishing with lapping. Cut from a slightly larger material, 2 or 4 surfaces are mirror-finished, and the surfaces other than the mirror surface are finished by grinding.

Accuracy

PV≤λ/2, RMS≤2nm, parallelism: within 30 seconds, dimensional tolerance ±0.1

Punch, Die Mold Surface Grinding

Product Description

We manufactured a punch die mold by surface grinding for the mold material. Finished with a sharp edge.

Accuracy

Thickness tolerance ±0.005・Flatness 0.003

Alumina precision parts

Product Description

I made 4x5x100 alumina precision parts. The 4mm thick part is surfaced with GC lapping and then mirror finished. After cutting to length, it is finished to 100mm by surface grinding. The 5mm width part is cut by cutting and then surface ground. Finished with

Accuracy

Parallelism 0.00015, Perpendicularity 0.03
