STC-18CNC

CNC Centerless Grinder

Specification:

  • HYDRUALIC DRESSING UNIT
  • A hydraulic dresser is equipped on both grinding & regulating wheels. Various types of from dressing can be achieved with optional template.

  • WHEEL SPINDLE
  • The hydrostatic Babbitt type spindle bearing with a 3 point support design and pressurized, filtered , recirculating oil system, eliminates metal-to-metal contact, thus providing a heavy duty grinding capability as well as high vibration dampening performance. A pressure switch interlock prevents spindle start-up until oil pressure is established. The pressure switch interlock also stop the spindle if the oil pressure fails, thus providing a longer spindle life.

  • MACHINE STRUCTURE
  • The machine base is made of Meehanite casting, which is normalized and stress relieved, providing maximum rigidity to assure machine stability and vibration free operation.

  • HYDRAULIC SYSTEM
  • The hydraulic & lubrication system is air cooled to maintain constant oil temperature, and is also separated from the machine to eliminate vibration and dissipate heat.
