大宮マシナリー List of Products and Services

The "OC-12BR-100" is a compact coreless grinding machine that adopts an inverter-type direct drive system for the adjustment wheel drive, allowing for stepless speed changes. Both the grinding wheel shaft and the adjustment wheel shaft are supported by precision multi-row cylindrical roller bearings (cantilever type) and utilize a grease lubrication system, making it oil-free. By employing a motor drive system for both grinding and adjustment in the truing device, the need for a hydraulic unit has been eliminated. 【Features】 ■ Oil-free operation using grease lubrication ■ Stepless speed changes possible ■ Motor drive system for both grinding and adjustment in the truing device ■ No hydraulic unit required ■ Compatibility with parts from 12A and 12HS *For more details, please refer to the PDF document or feel free to contact us.

The "OC-12HS-I" is a small coreless grinding machine that generates minimal heat from the bearings due to the complete absence of metal contact, offering a lifespan that is virtually permanent and maintenance-free. The static pressure bearings lift the shaft using hydraulic pressure, allowing for high rotational precision and enabling ultra-precision grinding. The slide features two tables, upper and lower, and the cutting handle is designed with a focus on operability, allowing for both coarse and fine feed. 【Features】 ■ The journal bearings of the grinding wheel shaft are static pressure bearings. ■ The bearing rigidity can be significantly increased by adjusting the hydraulic pressure, enabling heavy grinding. ■ The lifespan is virtually permanent and maintenance-free. ■ The cutting handle is designed with a focus on operability, allowing for both coarse and fine feed. ■ The bearing arrangement without a front bearing makes it easy to replace the grinding wheel. *For more details, please refer to the PDF document or feel free to contact us.
