  • 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.
