Please refer to the picture below:
- 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).
GW and RW are cantilever type ,easier for wheel changing.
GW fixed on the machine bed, with better reliability and stability.
Adopts multi-pieces bush-bearings for the wheel spindle, better rigidity for grinding durability.
2.3. Feeding
The flat-V shaped guideway & ball screw equipped servo motor supports the regulating wheel feeding.
Servo motor drives ball-screw through shaft coupling, min. feed 0.001mm.
2.4. Dressing for GW and RW
GW and RW dressers: Hydraulic cylinder for reciprocating motion, hand wheel for dresser feeding.
2.5.Electric
Converter for RW motor, step-less speed adjusting.
Operation panel with dials and touch screen for grinding, dressing,feeding, etc. Adjusting.
Mitsubishi PLC control system, Siemens for optional.
2.6. Cooling and lubrication
Coolant paper tape filter with magnetic separator. (optional configuration)
