Dragging plate mechanism combination and screw rod vice mechanism are covered, in the horizontal plane the angle of cut in 90 °, adjustment is mobile by work in chuck on power head device
The circular arc camber center of circle of part is moved on work table rotation central point, makees concentric circles synchronous revolving.
By the variable transmission suitable rotation rotating speed of chuck and workpiece of power head device.
Grinding head device is installed, pedestal has two sets of dragging plate mechanism combinations and screw rod vice mechanism, adjustment movement on bearing frame plate
The outer circle of grinding wheel is in contact with workpiece circular arc curved surface, when grinding wheel is rotated by motor and high speed transmission belt, generation is bent with circular arc
Mill processing on face.The rotation of screw pair and displacement grinding wheel makees manually or automatically feeding processing.Since workpiece rotation generates simultaneously
It is turned round with the center of circle of circular arc camber, so that grinding wheel cylindrical is moved circular arc camber by the center of circle and radius revolution, reach entire circular arc
The full surface mill processing of revolution solid of curved surface.
Replacement grinding wheel is fabric disc, becomes high rotating speed polishing, improves surface smoothness.
The grinding wheel center height of grinding head device is equal with workpiece axis center height, and the grinding working face of grinding wheel is vertical with tangential direction
It is directed at the circular arc center of circle, is unshifted in grinding wheel mill, and workpiece rotation and revolution, realize Compound Machining.It is driven using contiuously variable transmission,
It is conveniently adjusted the rotating speed that different size workpiece is more suitable for, improves precision and benefit.
