Features

 

Reduced Manual Intervention
Equipped with an automatic feed mechanism (1.5 mm/rpm) and 0.01 mm indexing feed, ensuring that feeding and dimensional adjustments are performed at set intervals, reducing repetitive manual operations.

 

Expanded Contact Width
The P600×200×305 mm grinding wheel provides a 200 mm axial contact width, allowing for a longer area to be covered in a single grinding pass, thus reducing the need for multiple tool passes.

 

Suitable for Medium to Large Diameters
Machining range of 10–150 mm, with a 285 mm center height, and adjustable guide wheels and support plates to position workpieces of different sizes.

 

Matching and Eliminating Cycle Time

A 22 kW motor with a speed of 1115 r/min provides power input under a wide range of grinding wheel conditions.

 

 

Applications

 

Automotive Parts: Used for machining medium to large diameter shafts, enabling continuous production with automated feeding.

 

Bearings and Sleeves: Used for machining outer rings and sleeves, reducing manual loading and unloading.

 

Hydraulic Components: Used for machining pistons and mating parts, with automated feeding matching batch processing cycles.

 

General Machinery: Used for machining shafts of various specifications, reducing operational steps through automation.

 

 

 

FAQ

 

Q: What scenarios are suitable for automatic feed?

A: Suitable for batch production of workpieces with fixed dimensional variation patterns, enabling continuous machining with a feed rate of 1.5 mm/revolution.

Q: How to adjust for workpieces of different specifications?

A: The guide wheel position, pallet height, and guide wheel speed (10–200 r/min) need to be adjusted. The feed rate is set via indexing (0.01 mm).

Q: When to use micro-feed?

A: When fine-tuning of dimensions is required, a 0.005 mm micro-feed orifice can be used for compensation to correct small dimensional deviations.
