1.1Machine Body

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

1.2 GW and RW(Regulating wheel)

GW is 500mm in diameter, 250mm wheel width for larger grinding amount and higher efficiency
RW fixed on the machine bed, adopted double supported structure , with better reliability and stability
Five pieces bush-bearings for each side on the GW spindle, better rigidity for fine heavy grinding

1.3.Feeding

SCHNEEBERGER brand high rigidity linear guide-rail for motion sensitivity, easy micron feed, vibration resistance, and anti-fraying.
Servo motor drives ball-screw through shaft coupling, min. feeding amount 0.001mm.

1.4.Dressing for GW and RW
GW and RW dressing:Servo motors drive ball-screws for GW dresser feeding and reciprocating

1.5.Electric

Converter for RW motor, step-less speed adjusting
Operation panel with dials and touch screen for Operation panel with dials and touch screen for
grinding, dressing,feeding, etc. Adjusting
Mitsubishi PLC control system, Siemens for optional.
