Centerless Grinding Machine M1040B

Centerless Grinding Machine M1040B:

• Versatility of machining methods: The machine supports two main operating modes: through-feed grinding (for mass production machining of cylindrical surfaces of shafts and rings) and manual plunge grinding (for machining stepped, tapered, and complex cylindrical surfaces).

• High stability and rigidity of the machine bed: The bed is cast from high-quality cast iron and has undergone heat treatment. This ensures minimal deformation, high wear resistance, and the retention of precision throughout its entire service life.

• Precision spindle system: The grinding and regulating wheels feature an overhung (cantilever) design for ease of maintenance. The grinding wheel spindle utilizes multi-segment long-sleeve hydrodynamic oil bearings, while the regulating wheel spindle is supported by a solid tapered plain bearing (1:30 taper), guaranteeing the highest rotational accuracy and vibration-free operation.

• High-precision feed mechanism: The feed guideways of the regulating wheel head feature a dovetail design with needle rollers, and the movement is actuated via a differential lead screw. This construction allows for exquisitely precise micro-feeds (down to 0.002 mm per division).

• Effective hydraulic dressing system: The reciprocating motion of the dressers for both the grinding and regulating wheels is driven by a hydraulic system. The system is equipped with infinitely variable speed control, allowing for the maintenance of the ideal geometry and sharpness of the abrasive wheels.

• Modern electrical control: The rotational speed of the regulating wheel is controlled by an AC variable frequency drive (VFD/inverter). This ensures smooth starting, precise maintenance of the set RPM, and the flexibility to adapt grinding parameters to different materials and tasks.
