It is a waste to throw cutting tools away after use! We revitalize such tools and they will look even better than new ones.

Tool regrinding and new tool making
We do not just grind worn areas or simply regrind steel. We first check the materials to be machined and machines to be used. After that, we suggest the optimum tools for grinding in order to revitalize the tools in use to make them better than brand new tools.
■ Variation of revitalization
・End mill (Extra-hard end mill, HSS end mill, Ball end mill, Roughing end mill)
・Drill (Stepped drill, Burnishing drill, unique drills of various makers)
・Reamer (Reamer, Burnishing reamer)
・Special cutter (Side cutter, T-slot cutter, Boring cutter)
Various cutting tools・Forming special tools (Profile machining)
・cBN diamond sintering body
■ Range of application
Recent mirror surfacing
Actualizing highly accurate flat surface, which has no grinding trace, using recent mirror surfacing technologies developed jointly with Institute of Physical and Chemical Research, an independent administrative agency.
■ Advantages
・Stress decentralization
・Improvement of roughness of ground surface
・Inhibition of heat and adhesion phenomena
・Improvement of coating
・Upgrading tool characteristics
Custom-making of special tools for materials difficult to machine
Zero-based manufacturing of tools optimum for the cutting environment. For example, we have developed the exclusive machining tools for materials which is difficult to machine together with a company producing engines made of heat resistive steel for jumbo jet aircrafts. In comparison with competitor's current products, the durability was improved by several times more.
