    ROTARY SURFACE GRINDER WITH VERTICAL SPINDLE (RR)  
       
       
 

This series is designed for flat grinding of one side of the job at a time for each table load.

 
       
       
 

Table diameter 500 to 1500mm
Spindle drive: 5.6 KW to 56.25 KW
Wheel clearance: 200 to 500mm

 
       
       
    Rotating Table RR  
       
       
 

Rotary work table operates on large, circular ways-well lubricated by    means of an oil sump. It carries an electro magnetic chuck with circular    poles.

 
       
       
 

Access to work table is unique, in that a greater proportion of work    table is opened for easier and safer work handling. Being a fixed centre table,    the initial accuracies are maintained for entire life if the machine.

 
       
       
 

Wheel Spindle Head is of extremely rigid construction. With precision    bearings duly preloaded. Segmented wheel is directly mounted at    lower end.

 
       
       
  Column has oversize vertical vee and flat ways-fully protected from grinding dust and coolant by sliding steel guards. Wheel feed can be  applied by hand or power. Precision Screw gives positive down feed on the head for accurately controlling small increments of feed.  
       
       
 

CONTROLS as Optional:

 
   
  1. Automatic electronic gauging is provided. It gives continous measurement of work during grinding cycle and visual indications that    the work is approaching size. When work reaches a preset dimension    grinding stops, the machine sparks out and the Head retracts- Since    the job is directly probed, Wheel wear is directly compensated.

  2. CNC controls for Vertical axis with servo drives via precision ball screw.
