Product Description
1.1 Machine Body
Casting, meticulously treated through natural aging and artificial heat treatment processes to ensure optimal deformation resistance and heightened durability.
1.2 GW and RW (Regulating Wheel)
GW: Features a robust double support structure with a hydrodynamic bearing design for the spindle, maximizing grinding rigidity.
RW spindle: Double row cylindrical roller bearing structure, ensuring superior rotational accuracy.y
RW employs a durable double supported structure, with spindle lubricated by grease for a long-lasting life; requires no additional oiling.
RW: integrated with a reliable gearbox for RW spindle transmission.
1.3 Feeding
This machine boasts a double-sided movement layout, with the work rest securely affixed to the bed.
The feed guide rail of the RW frame and GW frame features a flat V-shaped plastered guide rail for enhanced stability.
Both the RW frame and GW frame are driven by a precision servo motor with ball screw, offering a minimum feed accuracy of 0.001m.
1.4 Dressing for GW and RW (6 Axes)
GW dresser:
Equipped with a linear guide for the reciprocating guide rail of the GW dresser.
The servo motor drives a ball screw for feeding and reciprocating, maintaining a fine minimum feed of 0.001mm.
RW dresser:
Incorporates a linear guide for the reciprocating guide rail of the RW dresser,with a servo motor driving the ball screw for feeding and reciprocating,
ensuring a precise minimum feed of 0.001mm.
1.5. Cooling
Features a state-of-the-art cooling tank with a magnetic coolant separator and paper tape filter for optimal performance.
1.6. Electric
The operating system utilizes the advanced Q series PLC system by Mitsubishi.
Users have the flexibility to configure and purchase components tailored to their specific needs.
1.7. Special Configuration
Includes an efficient loading and unloading mechanism; a cantilever type lifting device for handling grinding and regulating wheels; and the SBS dynamic balancing system for GW.
