  • Two longitudinal V ways and two cross V ways for maximum rigidity.
  • The length of the bed way is more than twice that of the work table to ensure no overhang of table during different grinding conditions.
  • Automatic cross feed with intermittent and continuous mode.
  • Slide ways are hand scraped and TURCITE coated for higher wear resistance.
  • High precision spindle is supported by multiple anti-friction bearings adjusted radially and axially for greatest accuracy. They are permanent sealed with high quality grease for minimum maintenance.
  • Bed and base castings are twice annealed to relieve stress and to ensure accuracy.
  • Hydraulic table movement is controlled by unique directional valve that minimize vibrations.
  • Automatic lubrication system.
  • Optional programmable spindle down feed system with user friendly control.

THE PROGRAMMABLE SPINDLE DOWNFEED SYSTEM (optional)
The system is built specifically for the surface grinder to take over the control of spindle wheel downfeed movement. The numerical control system allows the operator to synchronize spindle vertical feed with longitudinal and cross feed of table for various grinding modes, such as plunge grinding or slot grinding.
