These grinding wheels are designed for the final finishing of bearings. We will select the grinding wheel best suited for the raceways of various types of bearings.
These grinding wheels are highly regarded for the ultra-precision grinding of bearing raceways. CBN, we offer a wide lineup that includes CBD grinding wheels designed for superior cutting performance and DBN grinding wheels designed for superior surface finish accuracy, enabling us to design grinding wheels tailored to your specific needs.

These are grinding wheels designed for precision grinding of bearings, automotive parts, home appliance parts, and other precision mechanical components. We manufacture vitrified-bonded grinding wheels—ideal for precision grinding—using our proprietary manufacturing process.

New dress drive unit with compact, high-rigidity, high-output spindle a high-sensitivity AE sensor is built in to check the forming condition of the grinding wheel with high accuracy.

Our original coating technologies utilizing the chemical vapor deposition method can be applied on tools with any complicated shape while retraining both high adhesiveness to base metal and excellent wear resistance. With choice of the right type and thickness of coating depending on the application, these tools are most suitable for processing carbon, ceramics, and FRP.

Single-use type (no regrinding required) for iron-based materialsCBN “Sun-Night Twin” indexable inserts for iron-based materials. They offer excellent cost-effectiveness, and the two corners areCBN cutting edges, they help reduce tooling costs during machining.

With our processing know-how and a wide selection of diamond/CBN blanks, we offer standard and custom-made products and also special specification (chip breakers, wipers, etc.) designs to improve productivity in processing various materials (aluminum, nonferrous metals, hardened steel, cast iron, sintered metals, etc.

To meet the market demand for higher productivity, we developed helical type drills with a diamond compact to achieve rapid feeding and reduces thrust. Also available are special types that solve exit burr and chip obstruction problems.
They also enable process integration by adopting one-pass finish and multistep edges.

[Endmill]
Purposely designed edges to cater for your needs to improve the efficiency of various types of processing such as milling, grooving, spot facing, and curve facing. Also available are spiral types for high-speed cutting, high-precision ball shapes, and taps. Applications include high-precision and high-efficiency processing of metal molds, compressors, FRP, acrylic, etc.
[Routers & Tipped Saw]
They allow you to cut costs because they produce a long lasting surface finish in cutting, grooving, and boring of wood, building materials, printed-circuit boards, artificial marble, plastics, etc. and have a long life, Also, we meet a wide range of demands such as whole form processing by combining them.

By integrating the tooling holder and reamer into a single unit, tool length can be shortened and rigidity can be increased to meet high precision requirements. Also, we can be manufactured in accordance with various holder standards.

With a focus on consistent quality based on the control of key reamer specifications—such as outer diameter and runout tolerance—our designs can accommodate high-precision requirements, including surface roughness, roundness, and concentricity, as well as high-speed feed rates. We meet our customers’ needs with a wide range of products, from standard specifications to value-added options.
