Product Description: Discover unparalleled efficiency and precision with our state-of-the-art High-Efficiency Centerless Grinding Machine, expertly crafted for the meticulous demands of precision bearing ring production.
1.1 Machine Body
Casting, natural aging, and artificial heat treatment. This meticulous process ensures optimal deformation control and significantly enhances the machine's durability for long-lasting performance.
1.2 GW and RW (Regulating wheel)
GW: Engineered with a robust double support structure and a sophisticated hydrodynamic bearing design, ensuring exceptional grinding rigidity and precision.
RW spindle: Double row cylindrical roller bearing structure, delivering superior rotational accuracyy
RW features a double-supported structure, augmented by grease lubrication that requires a single application for extended life, eliminating the need for continual oil maintenance.
RW: Equipped with a gearbox for RW spindle transmission, ensuring unparalleled reliability and performance.
1.3 Feeding
The machine incorporates a double-sided moving layout, with the work rest solidly anchored to the bed for stability.
The feed guide rail of RW and GW frames utilizes a precise flat V-shaped plastered guide rail for smooth operation.
Both RW and GW frames are operated by a servo motor with a ball screw, achieving a remarkable minimum feed increment of 0.001m.
1.4 Dressing for GW and RW (6 Axes)
GW dresser:
Outfitted with a linear guide for the reciprocating guide rail, enhancing the GW dresser's precision.
A servo motor powers the ball screw, ensuring precise feeding and reciprocating actions, with an extraordinary minimum feed of 0.001mm.
RW dresser:
Similarly equipped with a linear guide for the reciprocating guide rail, maximizing RW dresser accuracy.Driven by a servo motor, the ball screw guarantees exact feeding and reciprocation.
Boasting a minimal feed capability of 0.001mm for unmatched precision.
1.5. Cooling
An advanced cooling tank featuring a magnetic coolant separator and a paper tape filter for optimal fluid management.
1.6. Electric
The system is powered by the cutting-edge Q series PLC system from Mitsubishi, offering unmatched operational control.
Fully customizable, allowing users to tailor configurations according to their specific requirements.
1.7. Special Configuration
Includes a sophisticated loading and unloading mechanism, a cantilever-type lifting device for grinding and regulating wheels, and an SBS dynamic balancing system for the GW, ensuring precision and efficiency.
