Kato Kenma Seisakusho Co., Ltd.

We are a group of grinding engineers who satisfy customer needs with micron-level accuracy.

Our company mainly performs precision grinding as well as part manufacturing for molds and special-purpose machines, machine tools, and jigs and tools. We use various grindstones for a wide range of materials. We guarantee precision of 2 μm or better regarding dimensions, flatness, parallelism, and squareness with our plane grinding equipment. We can perform processing of diameter 0.5 or larger with out in-house grinders. We have achieved precision of 2 μm or better for outside diameter concentricity. We have a system for fully ensuring quality by making use of various measuring instruments and completely controlling temperature and humidity to prevent changes in product dimensions.

[Company strength]
Our company is a group of grinding engineers who satisfy various precision grinding needs. We apply the grinding technology we have been accumulating for more than 50 years to manufacture various precision parts. Measurement techniques as well as techniques for operating various kinds of grinding equipment are required to achieve micron-level precision. We control dimensions and precision by making use of a wide range of measuring instruments and gauges as well as the measurement techniques of our expert staff. We have temperature control and air cleaning equipment in our plant and control room temperature to 20 °C ± 1 °C. This is to prevent changes in product dimensions so we can fully ensure precision.

[Business description]
