Abrasives: Grinding Wheel

Machine application:
The machine is used for mass-producing cylindrical parts, ring parts in the way of centerless through feeding. And it also can be used for grinding cone parts with taper less than 1∶20 and molding rotational parts in the way of centerless in-feeding. The machine can carry out auto plunge-in feeding cycle if it is equipped loading & unloading mechanism (optional). It grinds circulation automatically. Suite for volume production.
Machine configuration & characteristics:
The machine layout adopts both sides feeding type. The gri. wheelhead is positioned on the left top side of the machine base and it feeds along with the bed guideway relatively with the workrest. The workrest is fixed in the middle of the machine base. The reg. wheelhead is positioned on the top right side of the machine base. It moves along with the bed guideway relatively with the workrest for feeding adjustment. The machine base is inblock cast with high rigidity and reasonable structure. The casting surface is very smooth.
The grinding wheel spindle is supported in both sides. Several short segments with ball pivot; filmatic bearings; are responsible for supporting spindle while two sleeves are installed on spindle both sides. Wheel motor equipped with converter, installed in the rear side of wheelhead; drives pulley and coupling transmitting wheel spindle.
Regulating wheel spindle is also supported in both sides where installed high precision roller bearings with high rigidity and precision. Double row cylindrical roller bearing is used in radial direction while a pair of angular contact ball bearing for axial runout controlling. AC motor drives reg. wheel and carries out stepless speed regulation by variable frequency.
The gri. wheelhead feeding is available for machine main feeding driven by servomotor via ball screw transmitted by reduction gear box. The wheelhead is mounted on the left side of machine bed. The feeding guideway is plastic coating type in order to make feeding sensitive and absorb vibration.
The reg. wheelhead is mounted on the right side of machine base and feeds manually on flat-v guideway.
The grinding wheel dress is located in the rear up side of gri. wheelhead. Single point diamond pin is available for dressing. Both feeding and reciprocating are driven by servo motor, so that synchronous tracking compensation related with gri. wheelhead can be achieved.
The RW. dresser is mounted on the top side of the RW. rotary body. A certain angle adjustment of this dresser can be realized. The displacement of single point diamond pen can be adjusted for dressing. The dressing is manually fed while the reciprocation is driven by gear motor.
