A surface grinder is a type of grinder that grinds the flat or shaped surface of a workpiece. The main types are horizontal axis rectangular table, horizontal axis round table, vertical axis rectangular table, vertical axis round table and various special surface grinders.
The outstanding advantages of surface grinder processing are:
1. High precision and stable quality of machined parts
The positioning accuracy and repeat positioning accuracy of the surface grinder are very high. It is easier to ensure the consistency of a batch of parts. As long as the process design and procedures are correct and reasonable, coupled with careful operation, the parts can be guaranteed to obtain high machining accuracy and easy to align. Quality control is implemented during processing.
2. High degree of automation, which can reduce the operator's physical labor intensity
The machining process of the grinder is automatically completed according to the input program. The operator only needs to start the tool setting, load and unload the workpiece, and change the tool by the EDM cutting machine. During the machining process, the main task is to observe and supervise the operation of the machine tool.
Third, the size marking should conform to the characteristics of the grinding machine processing
In CNC programming, the size and position of all points, lines, and surfaces are based on the programming origin. Therefore, it is best to give the coordinate size directly on the part drawing, or try to quote the size with the same datum.
Four, unified geometric type or size
It is better to adopt a uniform geometric type or size for the shape and inner cavity of the part, so that the number of tool changes can be reduced, and it is also possible to apply a control program or a special program to shorten the length of the program. The shape of the parts is as symmetrical as possible, which is convenient for programming by using the mirror machining function of the surface grinder to save programming time.
