Machine Performance and Technical Data

2.1 Machine Body

Casting, natural aging and artificial heat treatment for reasonable deformation and better durability.

2.2. GW and RW(Regulating wheel)

◆The grinding wheel designed for single supporting type, while grinding bracket fixed.

◆The spindle of grinding wheel adopted muti-plate long bearing bushed static-hydro dynamical oil film bearing.

◆Double row cylindrical roller bearings for GW spindle.

◆RW adopted double supported structure, equipped with double row cylindrical roller bearings, rotary accuracy assured.

2.3. Feeding

◆The regulating wheel feed slide is equipped double “V” roller guideway and and servomotor that drives ball screws.

◆Servo motor drives ball-screw through shaft coupling, min. feeding amount 0.001mm.

2.4. Dressing for GW and RW

◆Servo motors drive ball-screws for GW dresser feeding and reciprocating.

2.5.Electric

◆Converter for RW motor, step-less speed adjusting.

◆Operation panel with dials and touch screen for grinding, dressing, feeding, etc. Adjusting.

◆Siemens CNC 808 control system.

2.6. Cooling and lubrication

Coolant paper tape filter with magnetic separator. (picture on the left)

2.7 Semi-cover:

Electromagnetic lock while machine running for protection.

◆Crane for GW and RW (picture on the left); ◆Coolant and oil mist filter(picture on the right )
