広山金属加工研究所 Company Profile

Please consult our company for the production of shank-type pinion cutters, formed cutters, screw grinding, the production of screw electrodes for molds, and precision grinding.

Hiroyama Metal Processing Research Institute, Ltd. was established in 1966 as a manufacturer of gear cutting tools. We have expanded our business scope to include grinding processing of various precision parts by applying the technology we have cultivated in that field. Without falling into "self-satisfaction" or "one-way communication," we will continue to place greater importance on "communication" with our customers and propose "accuracy," "delivery times," and "costs" that you can be satisfied with.
