Classification of Grinding Processes

Classification of Grinding Processes:

Classification by Type of Abrasive: Grinding processes can be divided into two main categories: fixed abrasive and free abrasive.

2. Classification by Type of Workpiece and Surface Generation Method: Grinding processes can be divided into six basic types based on the workpiece and surface generation method: plane grinding, cylindrical grinding, internal cylindrical grinding, centerless grinding, free grinding, and face grinding with a cylindrical grinding wheel.

3. Classification by Relative Motion. Between Abrasive Wheel and Workpiece: Grinding processes are usually classified into three types: reciprocating grinding, feed-in grinding, and combined grinding.

In reciprocating grinding, the radial position of the abrasive wheel remains constant, while there is relative movement in the axial direction. This processing method has good processing quality but low efficiency.

Feed-in grinding refers to the processing method in which the relative position between the abrasive wheel and the workpiece along the axis of the abrasive wheel remains unchanged, and the abrasive wheel feeds in radially at a constant speed until the workpiece size is ground to the required size. Feed-in grinding has high processing efficiency but poor processing quality.

Combined grinding combines the features of feed-in grinding and reciprocating grinding. It starts with feed-in grinding to remove most of the workpiece stock in sections, and then uses reciprocating grinding to remove the remaining small amount of stock. This method can achieve both high efficiency and good surface quality.
