High Precision Surface Grinding Machine

High Precision Surface Grinding Machine


Cosmos Grinding Technologies Pvt Ltd offers Jupiter Series of high precision Surface Grinding Machine. The jupiter series varies depending upon the Grinding area as JR-400, JR-600, JR-800 and JR-1000. It is a precision rotary table surface grinding machine that can efficiently produce small parts as well as large cylindrical components with superior accuracies. The rotary table is driven by a directly coupled motor which ensures efficient power transmission. The advantages of rotary table over reciprocating table is that the grinding wheel is constantly in touch with workpiece which results in, higher productivity & precision.
Advantages:

  • Constant surface speed of table gives better surface finish
  • Higher material removal capacity
  • Convenient working & simple to operate
  • Superior precision
