Automotive Parts Industry

Balance Shaft, Nozzle Needle

It is said that an automobile consists of approximately 30,000 parts. In particular, parts used in engines, injectors, steering, and transmissions, which are a collection of rotating parts, require the utmost precision. Our grinders have a proven track record in providing optimal processes for a wide variety of parts, including pistons, valves, injector bodies, nozzle needles, and plungers. Especially for eccentric workpieces such as balance shafts, we offer models with inclined beds, which is one of our specialties, to meet high precision requirements and production efficiency.
In recent years, we have been offering grinding machines for machining motor shafts in response to the electrification of automobiles, as well as centerless grinding machines for mass-production thread slot grinding to meet the machining of screws for the drive actuators used in motors.

Construction Machinery Industry

Spools and pistons

Construction machinery parts are required not only to be round (roundness) but also to be straight (straightness).
The highly rigid equipment characteristic of our grinding machines enables us to finish spools for control valves, which are very delicate, to a high degree of precision. For pistons with unusual shapes, we can achieve the desired shape with high quality by employing total dressing.
In recent years, demand for construction machinery has been increasing in emerging countries with remarkable growth, and many local construction machinery manufacturers have adopted our grinding machines.

Medical Devices

Catheters, syringes

The shape, material, and size of the same medical device varies depending on the application and treatment area. In recent years, there is a need for more patient-friendly, minimally invasive medical devices, which require high machining accuracy. We make the most of the advantages of our grinding machines to provide grinding processes that meet the needs of the medical field, such as the processing of long wires with diameters of 0.5 mm or less and the mass production of carbide instruments. Other machining processes can also be studied at our test center, so please contact us for more information.

Bearing Industry

Bearings are used in a variety of rotating applications, including axles of automobiles and bullet trains, which rotate shafts accurately and smoothly. High machining accuracy is required for parts because they must reduce energy loss and heat generation due to friction and prevent seizure. We offer a lineup of in-feed and through-feed machines that use centerless grinding machines with inclined beds to meet customer requirements.

Others

Our grinding technology is not restricted to conventional grinding and can be applied to a wide range of fields.
For example, we have experience in grinding difficult-to-machine materials such as titanium, Inconel, and ceramics, which are often found in the aircraft industry, carbon, which is found in semiconductor manufacturing equipment, and sporting goods such as golf balls and driver shafts. We can also provide grinding processes for all kinds of materials, including magnets, glass, resin, and rubber. If you have any problems with grinding, please contact us for a trial production at our well-equipped test center.
