Precision parts processing

On this page, we will explain about precision parts processing and introduce some of TDC’s precision parts processing results.

What is precision parts processing?

Precision parts processing refers to processing that meets requirements at the level of several nanometers to several microns in the fields of parts manufacturing and parts processing.

In general, precision parts are manufactured and processed by one of the following methods.

• Manufacturing and processing parts one by one from one material
  Using high-precision machine tools and tools, our engineers process parts one by one. It is suitable for manufacturing and creating parts in small lots.
• Make a mold and start mass production
  We prepare a “mold” for mass production in advance, and manufacture and process the parts. Mold making costs are required, but parts can be produced in large quantities.

For TDC’s precision processing services, please refer to “Precision lapping service / ultra precision lapping service“.

COntact TDC for precision polishing parts processing

At TDC, we can process precision parts of any material within the following range.

• Number of lots that can be handled: From 1 piece to mass production
• Available sizes: up to 700 square (depending on specifications, please contact us for details)
• Available shapes: plates, inner and outer diameters of rolls and shafts, 3D shapes, etc.

At TDC, we specialize in high-precision and high-precision micron-level parts processing using the polishing technology know-how we have cultivated over the years.

We also have a large number of machine tools that are indispensable for precision parts processing, and we can realize one-stop from design to processing, quality assurance, and delivery.

From mass production to prototype development products, we can handle small lot production from 1 unit, and mass production, so if you have any concerns about parts processing, please contact TDC.

Using precision polishing processing technology and know-how that has been cultivated over many years to stably realize high-precision manufacturing and cutting-edge measuring equipment, we process not only dimensional tolerances but also various geometrical tolerances to the nano-order.

Quality control and quality assurance for precision parts

At TDC, we use the world’s highest standard measurement environment and evaluation technology to ensure the quality of ultra-precision manufacturing.

The precision parts to be manufactured and processed are manufactured while measuring the surface roughness, flatness, parallelism, dimensional tolerance, dimensions, etc., and the quality is guaranteed by our precision measuring equipment.

We will provide quality assurance data at the time of shipment.

For TDC’s quality assurance, please also refer to the “Quality Assurance” page.
