Centerless Grinding Machine
Centerless grinding machine is a powerful engine valve grinding machine. It can grind round parts. We use it to grind stem of engine valve and groove of engine valve. it is fully automatic and at high speed. help you save cost and improve efficiency.
Grinding wheel spindle support is used five-piece liquid dynamic pressure bearings, rotary precision is good. Adapt AC inverter control motor to achieve automatic sub-variable speed, so as to achieve constant line speed. Max working speed: 45m/s.
Guide wheel spindle support with an inner taper of 1:10 as a whole type of sliding bearings; rear support with pairs of double angular contact ball bearings for radial and axial positioning.
The grinding wheel and adjusting device are servo-driven, step-less speed change, smooth dressing, and the dressing seat adopts special alloy cast iron, and is composed of heat treatment, precision guideway, and ball screw to ensure that the dressing is flat and straight.
