The honing machine is a method of finishing the surface of the workpiece at a low cutting speed. It is a special form of grinding and a high-efficiency machining process. It can improve the workpiece size and geometry accuracy and reduce the surface roughness of the workpiece, and is widely used in the finishing of inner holes.
1) After the new grinding bar is glued, it must go to the cylindrical grinder for "rounding", especially the diamond grinding bar. If it is not rounded, tens of thousands of products can be used normally. The rounding is to clamp the grinding head with the tooling, raise the grinding bar, and then smooth the grinding bar (average so far). Generally, the grinding head is equipped with this tool when it leaves the factory. When grinding, pay attention to correcting the outer circle of the grinding head first. It should be noted that the grinding bars after the rounding cannot be guaranteed to be evenly aligned, so it is necessary to pre-grind some workpieces for final correction.
2) The quality of the honing fixture will also seriously affect the roundness and cylindricity. The fixture must be calibrated, and the coaxiality and verticality with the main shaft should not be greater than 0.02.
3) The column degree is also related to your school's itinerary, so you should pay attention to adjustment.
