High Precision Centerless Grinding Machine Grinder for Shafts, Pistons and Bearings

Product Description

Product Description
1.1Machine Body
Casting, natural aging and artificial heat treatment for reasonable deformation and better durability.
1.2 GW and RW(Regulating wheel)
GW 600mm in diameter, 400mm wheel width for larger grinding amount and higher efficiency.
GW fixed on machine bed, double supported structure , with better reliability and stability.
RW and GW spindles double supported structure, double row cylindrical roller bearings.
1.3 Feeding Schneberg linear guide-rail for motion sensitivity, easy micron feed, vibration resistance.
Servo motor drives ball-screw through shaft coupling, min. feeding amount 0.001m
1.4 Dressing for GW and RW GW dresser: Servo motors drive ball-screws for GW dresser feeding and reciprocating.
RW dresser: Gear motor drives ball screw for reciprocating motion, step-less speed adjusting, hand wheel for dresser feeding
1.5.Electric Converter for RW motor, step-less speed adjusting.
Operation panel with dials and touch screen for
grinding, dressing,feding, etc. Adjusting.
Mitsubishi PLC control system, Siemens for optional
