Features

 

Reduced Clamping: The 600 mm wide grinding wheel expands the axial contact range, allowing through-feed machining to continuously cover longer areas, thus reducing repeated clamping and positioning.

 

Controllable Dimensions: The minimum grinding wheel feed is 0.002 mm, the guide wheel is 0.01 mm, and the dressing index is 0.01 mm, allowing dimensional compensation to be adjusted at fixed increments.

 

Adjustable Track: The guide wheel has a stepless speed regulation of 10–200 r/min, combined with a swing angle of -2° to +4° (vertical) and 0° to +3° (horizontal), controlling the workpiece feed speed and movement trajectory.

 

Coverage of Multiple Sizes: Applicable to diameters of 10–200 mm, combined with a 290 mm center height structure, different workpiece sizes can be positioned by adjusting the guide wheel and support plate.

 

 

Applications

 

Automotive Parts: Used for machining the outer diameter of shock absorber rods and drive shafts, supporting continuous feeding for mass production.

 

Bearings and Standard Parts: Used for machining outer rings and pins, achieving fixed length and consistency control.

 

Hydraulic Components: Used for machining valve cores and plungers, meeting mating dimensional requirements.

 

General Machinery: Used for machining various shafts and guide components, reducing the need for multi-model configurations.

 

 

FAQ

 

Q: How to choose the machining method?

A: For constant diameter, continuous production, choose through-feed; for stepped or fixed-length requirements, choose cut-in feed.

Q: What needs to be adjusted when changing specifications?

A: Adjust the guide wheel position, support plate height, and guide wheel speed to match workpiece positioning with feed.

Q: When is wheel dressing required?

A: When dimensional deviations exceed the minimum feed correction range or surface roughness changes, dress the wheel in 0.01 mm increments.
