Our Policy


Our company was founded in 1967 and worked as a manufacturer engaged in machining of measuring gages.
Our journey started with two units of machining equipment.
Soon after opening for business, we started machining of cemented carbide.
We set our goals on materials that are difficult cut to stand apart from other companies.

Machining technology of our Company

A diamond grinding wheel is used to machine cemented carbide, a material that is difficult to cut.
Planar and cylindrical external surfaces can be machined based on the capabilities of the machinery and equipment used.
There are physical restrictions such as the shape of the grinding wheel while machining inner surface of cylinders; this makes machining maintaining the accuracy of surface finish and dimensions in microns difficult.
The machining technology of our company makes the best use of traditional manufacturing.
This machining method is an effective means for improving surface finish, dimensional accuracy, and can be used for machining of difficult-to-cut materials.
The younger employees are now acquiring the machining technology that we cultivated from the time our company was founded.

Advancing to machining ceramics

The eighties saw a boom in ceramics.
Exhibitions were overcrowded, and there were new entrants to the market mainly from the chemical and ceramic domain.

Our company had also gained experience in machining ceramics.
We searched for new materials with this opportunity and started full-scale machining operations by signing agreements with raw material vendors and application development for ceramics.

At the same time, we were successful in getting information from public institutions.

Searching for applications

Fine ceramics are expensive, and initially, most of the orders we received were about the size of a palm.
To stand apart from our competitors, we focused on cylindrical shapes, a specialized field for our company.
Extensive application of ceramics can be observed in the semiconductor industry that makes use of insulation.
Our customers are mostly in the automobile industry, and their focus is on developing wear-resistant products.
In fact, wear resistance applications of ceramics revealed a drawback that ceramics are brittle.
Therefore, we started to search for applications where the “Sliding” properties of ceramics could be used in addition to wear resistance.

Difficulty in achieving 1 μm

The average manufacturing tolerance for products such as jigs and tools was mainly around 5 μm in our company.
However, with the passage of time, there was demand for more products with accuracy similar to gages.
We have developed products with values of roundness, straightness, runout of inner and outer diameters, perpendicularity of the end face to the inner surface less than 1 μm in addition to the absolute values.
The value 1 μm can be changed just by touching with bare hands or a long breath.
Measurement error can also occur with minor changes.
For absolute dimensions, we discuss with the customers and find out the accuracy requirements and then perform machining with extreme caution.

Company Motto

Needs of the customers has changed over time, and the products to be manufactured have also changed.
Our company wants to continue to manufacture products that will be useful for customers.
We will be pleased if people become aware of our company's existence through this website.
We sincerely hope that we can serve our customers by matching our machining technology to their needs.
