- Both grinding & regulating wheel spindles are made of NI-CR-MO alloy steel, which is normalized and carbonized hardened and ground for longer spindle life and better accuracy.
- Hydrostatic Babbitt bearings type spindle with a 3-point support design, surrounded by a high pressure oil film, eliminates metal-to-metal contact to provide heavy duty grinding capability as well as high vibration damping performance.
- A pressure switch interlock prevents spindle start-up until oil pressure is established. This pressure switch interlock also stops the spindle if oil pressure fails for longer spindle life.
- The regulating wheel travels on double V ways are hand-scraped and Turcite coated for precise and smooth movement to ensure high accuracy and longer way life.
- Both grinding & regulating wheels equip with hydraulic dressing unit. Dressing speed is infinitely variable. Various profile dressing can be achieved with optional template.
- Hydraulic dressing unit for the regulating wheel can be rapidly and precisely swiveled up to ±3°for grinding taper in infeed grinding and for providing better contact between workpiece and grinding wheel to achieve better surface roughness, roundness, & cylindricity.
- All gears in the gearbox are made of Chrome-Molybdenum alloy steel (SNCM-21), are hardened and precision-ground for smooth running and low noise.
- The hydraulic system is air cooled to maintain constant oil temperature and separated from machine to eliminate vibration and dissipate heat.
- Optional automatic loading & unloading for infeed & thrufeed can be custom-built to meet your requirements, so machine can run unattended, at a high production rate, while maintaining a tight tolerance.
