STD CYLINDRICAL GRINDERS

  • Universal Cylindrical Grinders for between center and chucking operations. Available in manual or automatic infeed.
  • Heavily ribbed box-type base made in Meehanite casting.
  • Rigid-designed workhead with precision bearings and variable spindle speeds. Workhead swings 90º CCW and 30º CW.
  • Strong casting tailstock is designed to carry MT3/MT4 or optional MT5. Optional hydraulic tailstock with pedal is available.
  • The wheelhead runs on V and flat guideways with Turcite coating by a micro stepping motor.
  • Cartridge type wheel spindle permanently lubricated and equipped with 4 super precision angular contact type bearings. Spindle motor with 5/7,5 HP.
  • Rigid work table travelling on a cushion of oil. The table is fully supported in the full travel avoiding overhang.
  • Hinged, the internal grinding attachment (optional) swings down into working position for easy and quickly internal grinding operation.
  • The machines can be customized with a wide selection of systems for automation as electronic probe, automatic OD sizing, dynamic wheel balancing, etc.
  • Mitsibishi PLC control uses a menu driven LCD touch screen for simple operation (NC models).
