Description of business
Precision machining
We are able to perform high-precision machining by utilizing cutting-edge machine tools, such as lathes and machining centers, and processing techniques performed by skilled workers. Please entrust us with processing even one difficult-to-process product. Our main products include shaft sleeves (ceramic deposition), bevel gears, pinion shafts, mechanical seal parts (dual axis), and bearing covers.  
Machining of complicated shapes
We perform machining of complicated shapes by utilizing 3D CAD. We are able to process materials to produce screw-shaped parts. Our main products include shape modeling by 3D CAD, tips of worm screws (Stellite® edges), Co-Kneader screws, and element screws.
Repair and maintenance
We repair and perform maintenance on machined parts including spherical bearings, rollers (replacing MC nylon), gear pump shafts, and V pulleys + pinion shafts.
Designing and producing equipment
We perform processes ranging from planning to design and production. We are able to produce a wide variety of equipment including belt conveyors, hoppers, silos, chutes, screw conveyors, table feeders, vibrating screens, and rotary valves. Please let us know the required performance and functions, and we will select and design the optimum equipment.

Metals and materials processed by us
-HARDOX
HARDOX improves the performance of equipment such as excavators, front wheel loaders, dump trucks, mining trucks, conveyors, chutes, containers, grinders, crushers, mixers, sieves, screens, crushing and dismantling machines, and barges. It also maximizes their operable time.
-Stellite®
The main component of Stellite®, an alloy, is cobalt. Approx. 30% of it is composed of chromium, and 4 to 15% of it is composed of tungsten and other metals. It is very hard, excels in abrasion resistance and antioxidative properties, and has characteristics that rarely change. Therefore, it is an all-round abrasion resistant alloy. Thanks to additives, it has highly excellent heat resistance. It is used for components in the engines of aircraft, vessels, etc.  
-COLMONOY®
Boron, silicon, and other substances are added to a Ni-Cr alloy which excels in corrosion resistance. The corrosion resistance of COLMONOY® is improved by the dispersion of hard boride and carbide. In particular, COLMONOY® alloys are greatly characterized by the dispersion of chromium boride. Thanks to the dispersion, they have excellent abrasion resistance.   
-Other metals and materials
TERO PLATE, CDP PLATE, Casto Tube, and shaft sleeves
