Special Purpose Cylindrical Grinder



CNC Series for Spindle

1000 mm

Distance between centers

Ø320 mm

Swivel over table

Ø300 mm

Max. external grinding dia.


The machine structure is strengthened with same design of heavy duty cylindrical grinder. The enlarge hydrostatic wheel spindle construction could equip max. 125 mm width grinding wheel for plunge grinding application.



High precision and high rigidity machine structure design

Advance the machine design structure. The lower center of gravity of the bed reinforces the machine rigidity.

The rigidity of the grinding wheel spindle is comprehensively improved. Fully enhance the cutting force and grinding efficiency.

The grinding wheel spindle with hydro-static bearing. No friction between metals, maximum wear resistance and enhance the lifetime.

Enlarge the spindle pitch and grinding wheel motor, enhance the grinding efficiency and shorten cycle time.

The closed loop Hydro-static slides

The slide is widened and thickened designed with fully-closed hydrostatic. The maximum loading weight of the workpiece is 500KGS.

The stroke of each axis is increased to meet the requirement of large-angle grinding

The X&Z axis strokes are increased to improve the grinding efficiency of the wheel.

The swiveling angle of the worktable is enlarged, providing the operator with their diversified processing demands.
