Features of Centerless Grinding
Centerless grinding is a method of grinding the periphery of a workpiece by adjusting the rotation and feed of the workpiece while supporting it between a fixed support blade, a rotating regulating wheel and a grinding wheel. The workpiece does not need to be mounted on the grinder, and the system can be used for small-lot to high-volume production. In addition, there is no deflection due to the workpiece's own weight during processing, and the grinding accuracy can be maintained uniformly.

Comparison with other polishing methods
Compared to cylindrical grinding and drawing, centerless grinding is a processing method that can meet a wide range of requirements in terms of cost, delivery time, and dimensional accuracy.
It is also suitable for small lots and a wide variety of products, minimizes distortion of long objects, and does not cause degeneration such as magnetization during processing.

Advantages of centerless grinding over cylindrical grinding
When the advantages of centerless grinding can be enjoyed
When you want to reduce the delivery time and cost, even if the accuracy is slightly reduced.
When you want to reduce the cylindrical grinding process.
When a high level of accuracy is required for long processing.

Advantages of centerless grinding over cylindrical grinding
■ Longer workpieces can be machined because the workpiece is not affected by warping.
■ High continuous machining capability reduces machining time.
■ High work efficiency due to large amount of cutting per time.
■ Cost can be reduced.

Advantages of combining cylindrical grinding and centerless grinding
Machining close to the same level as cylindrical grinding is possible with short delivery time and low cost.
The process of cylindrical grinding in the secondary processing of parts can be reduced to save labor, resulting in shorter delivery times and lower costs.

Recommendations from our company
Centerless grinding is inevitably less accurate than cylindrical grinding. However, it enables long processing and shortening of processing time, which cylindrical grinding is not good at, and we believe that the merits of centerless grinding can be maximized if ultra-high precision is not required. In addition, by combining the strengths of cylindrical grinding with the strengths of centerless grinding, it is possible to enhance precision while taking advantage of the benefits of centerless grinding.
