Precision machining of metal

This page introduces the precision processing of metals performed at TDC.

For more information on TDC’s precision polishing services, please also see the “Precision lapping service / ultra precision lapping service” page.

TDC’s Metal Precision Machining

At TDC, we can handle a wide range of precision metal processing, from precision parts that require the highest level of precision to metal processing for molds, and processing to create a mirror-like gloss on the surface of products. is.

We will solve the problems of metal processing of all kinds of precision and shape with the metal precision processing technology in micron units that we have cultivated so far.

Features of TDC’s precision metal processing

TDC’s precision metal processing has the following strengths and characteristics.

• High-precision polishing technology

TDC’s precision polishing technology enables ultra-high-precision metal precision processing at the micron and nano level by controlling the removal amount.
Compared to processing methods such as cutting and grinding, it is possible to handle any shape without applying a load to the object.

• Short delivery time and express service available

By owning more than 100 polishing machines, we can achieve short delivery times even for large lots and complex processing.
If you are in a hurry, we will also respond to consultation with “express response”.

• Please feel free to contact us even from a small lot.
  Please feel free to contact us for small lot orders starting from 1 unit and prototype production.
• Owns over 100 abundant processing machines
  

TDC owns more than 100 polishing machines such as lapping machines and surface grinders.
We also have various processing machines such as machining centers and milling machines, so we can handle all kinds of processing.

• About half of the polishing equipment is manufactured in-house
  About half of the more than 100 polishing machines are made in-house, realizing “low-cost” and “high-quality” manufacturing.

Metal that can be precision machined

We perform precision processing of metals using various processing technologies such as polishing and grinding, which are our strengths.

The representative metals that can be handled are as follows.

• General steel
• cemented carbide
• stainless
• copper
• Titanium
• Aluminum
• molybdenum
• tungsten
• nickel
• tantalum
• Various other metals

Examples of TDC metal precision processing

Here are three examples of typical metal precision processing that can be processed and manufactured with TDC.

Example of metal precision processing 1 : Accurate grinding of precision table

It is possible to achieve the ultimate precision in terms of flatness, parallelism, and plate thickness tolerance for precision stages and tables used in semiconductor manufacturing equipment that requires ultimate precision or in precision measuring machines.

• Material: SUS304
• Size: φ300xt30
• Processing details: flatness 0.0005mm, parallelism 0.001mm, plate thickness tolerance ±0.001mm

Metal precision processing example 2 : Internal mirror surface processing of pipe mold

Depending on the specifications, fine scratches and cloudiness, which were conventionally allowed, are often not acceptable in “mold” processing. Please experience the high-precision finishing of TDC once.

For example, when polishing a mold for “roller manufacturing” that is built into a printing machine, if it is a mold with a length of 300mm and an inner diameter of φ20mm, the inner diameter and coaxiality are controlled in a micro order, and the surface is polished. It can be finished to a roughness of Ra1nm or less.

Metal precision processing example 3 : Production of test pieces and test pieces with various materials

Please leave the production of specimens and test pieces that play an important role in the production of products.

It is possible to handle from the cutting process, and it is possible to make different products from a mirror surface with a surface roughness of Ra1nm to a satin finish (frosted glass state).

Please feel free to contact us not only for metals, but also for resins, ceramics, crystal materials, etc.
