Grinding machine is a machining method that completes the surface of a workpiece at low cutting speeds. It is a special form of grinding and an efficient machining process. It can improve the size and geometric accuracy of the workpiece, reduce the surface roughness of the workpiece, and is widely used for precision machining of internal holes.
When the new grinding rod is in good condition, it is necessary to make a "circle" for the external cylindrical grinding machine, especially for the diamond grinding strip. If not used for grinding tens of thousands of products, it can be used normally. Use a cutting tool to grind the grinding head, add grinding strips, and then grind the grinding strips (average to the end face). General grinding heads are equipped with this tool at the factory. When grinding, the first thing to pay attention to is the correction of the outer circle of the grinding head. It should be noted that when the equivalent gauge is circular, the honing strip of the honing machine cannot guarantee that all are equal. Therefore, it is necessary to pre process certain workpieces for final correction.
The quality of honing fixtures can also seriously affect roundness and cylindrical dimensions. The fixture must be corrected, and its coaxiality and verticality with the spindle should not exceed 0.02.
The column degree is also related to the stroke of the honing strip of the honing machine, and attention should be paid to adjusting it.
