CNC CYLINDRICAL GRINDER TRAVERSE WHEELHEAD

  • CNC Cylindrical Grinders for between centers and chucking operations. 2-axis CNC Traverse Wheelhead. Grinding length up to 4000 mm.
  • Heavily ribbed box-type base made in Meehanite casting. Optimum distance between the guideways offers excellent wheelhead support to increase Z axis positioning accuracy and repeatability.
  • Rigid-designed workhead with precision bearings and variable spindle speeds.
  • Strong casting tailstock is designed to mount MT4 and MT5. Optional hydraulic tailstock with pedal is available.
  • The wheelhead runs on double V guideways hand scraped with Turcite coating by a AC FANUC servo motor,0.001linear feedback and precision ballscrew.
  • Wheel Spindle with a combination of hydrostatic and hydrodynamic bearings surrounded by a high pressure oil film eliminates metal to metal contact.
  • Box type rigid work table with workhead and tailstock.
  • The machines can be customized with a wide selection of systems for automation as electronic probe, automatic OD sizing, dynamic wheel balancing, etc.
  • FANUC control with programs for standard applications.
