Japanese toolmaker relies on VOLLMER sharpening technology
Japanese toolmaker relies on VOLLMER sharpening technology
14.03.2018

The Japanese company Heiwa Sangyo from Tokyo supplies moulds, i.e. important components, to companies who make planes, rockets or trains. Moulds can be used to shape metal components or make castings. Heiwa Sangyo uses carbide cutting tools such as cutters, drills or reamers to machine these moulds. For the manufacture and the sharpening of the cutting tools the company relies on the VGrind grinding machine from VOLLMER. The specialist for grinding and eroding machines equipped its VGrind with automation solutions so that Heiwa Sangyo can machine carbide tools unmanned and around the clock.

 "We produce and sharpen moulds for our customers, who play a key role in the manufacturing industry, in order to shape or cast metal components", states Managing Director Dr.-Ing. Yasuhiro Yao of Heiwa Sangyo Co. Ltd. from Tokyo. "For machining the moulds we use cutting tools which we manufacture and resharpen with the VOLLMER grinding machine VGrind – automated and around the clock."

Whether it is an engine block, body, turbine or thread – whoever wants to manufacture such components from metal needs moulds for precise machining. The Japanese company Heiwa Sangyo supplies moulds, i.e. important components, for the metalworking manufacturing industry worldwide. Whether customers need frames and engines for planes, components for high-speed trains or rocket parts, Heiwa Sangyo specialises in the simultaneous and multi-axle machining and manufacture of moulds.

The company has been active on the international market in the metalworking industry for over 50 years and now employs around 180 staff. It manufactures customised equipment, moulds or castings. Besides the headquarters in Tokyo, the company has three production sites in Funabashi, Ichikawa and Komagane. Heiwa Sangyo has established itself as an important business partner in heavy industry and can count well-known companies such as General Electric and Rolls Royce on its list of international customers.

The company uses cutting tools such as drills, cutters or reamers made from carbide for constructing moulds. In order to produce and resharpen these moulds single-handedly, the company decided on the tool grinding machine VGrind from VOLLMER. The VOLLMER machine realises multi-level machining via two vertical spindles. As a result, Heiwa Sangyo can manufacture its cutting tools precisely, individually and in large quantities. Thanks to the automation with a pallet magazine, the VGrind can be operated around the clock and unmanned.

"The VGrind not only makes possible accurate production, but also many possibilities such as circular and cone grinding. An advantage that no other competitor has today", states Dr.-Ing. Yasuhiro Yao. "If one attempts, for example, to manufacture a ball cutter with a cone, the cone has to be machined first on a circular grinding machine, in order to machine it on another grinding machine – the VGrind from VOLLMER does all this in one step."

Another reason for choosing the VGrind from VOLLMER was that the Swabian sharpening specialist has its own subsidiary in Japan. This allows VOLLMER to provide local support to Heiwa Sangyo, whether it is maintenance, repairs or training. The use of automated VOLLMER machines helps to enable Heiwa Sangyo to secure the future of the company as a family-run business. With high-quality technology such as the VGrind, the company can offer added value and a uniqueness which also make Japan efficient and successful as a production site.

"As a medium-sized company, Heiwa Sangyo has established itself as a reliable partner in global industries such as aerospace and continually invests in expanding its expertise and skills", states Dr. Stefan Brand, CEO of the VOLLMER Group. "We do our utmost to ensure that smaller companies also obtain a competitive edge with our sharpening technology, which in turn makes them fit for the future."
