CNC Centerless Grinders Grind the External Surface by the Through Method

SGS Approved Manufacturer of plastic coupling 

The CNC centerless grinder uses the penetration method to grind the outer surface, that is, the workpiece is placed on the pallet and is driven to rotate by the guide wheel. Since the axis of the guide wheel is inclined by an angle of α relative to the axis of the workpiece, the horizontal speed is generated, which makes the workpiece move in the axial direction. In order to ensure that the guide wheel can be in a linear shape with the contact line between the workpieces after being inclined at a certain angle, the surface of the guide wheel should be trimmed into the shape of a hyperbolic revolving body. SGS Approved Manufacturer of plastic coupling 
Numerical control system centerless grinding machine: Adopt Japanese Fanuc OIMD numerical control series, with Fanuc servo motor, good compatibility, easy operation, accurate feed, and automatic sand compensation.
Rails:
The static pressure guide rail adopts Japanese THK ball screw, equipped with Naco CNC system and servo motor, and the minimum feed size can reach 0.0002mm.SGS Approved Manufacturer of plastic coupling 
Grinder base: The base and nine major components are made of high-grade cast iron fc-30 (ht300). Heat treated by manual normalization. After natural aging treatment. The nine major components are processed by one-time clamping with Japanese yasda, mitsuiseiki, toshiba, elb and other equipment. The precise size can reach the micron level, ensuring the high precision of the basic components of the equipment.
The main shaft of the grinding machine adopts the original main shaft, using sncm-21h alloy steel, after quenching and tempering, carburizing heat treatment and then computer-controlled cryogenic treatment, the surface hardness is above hrc-62: the effective hardening layer on one side is above 1.5mm, durable and stable good sex. SGS Approved Manufacturer of plastic coupling 
Adjusting the wheel drive system
The spindle drive motor of the adjustment wheel of the CNC centerless grinder adopts Delta, the speed control is 0~250rpm (digital control) stepless speed change, adjust to the best line speed, when the outer diameter of the adjustment wheel changes, it can still maintain the same line speed, and grind the most best product.
