Causes of the aperture enlargement
1) the design value of out diameter size of the reamer too large or the edge of the reamer has bur, using speed 10o high
2) improper speed C excessive processing allowance. excessive main deviation Ange of the reamer, bending of the reamer, and chip tumor adhering 0 the edge of the reamer.
3) the edge saving error of the reamer Is out of tolerance when grinding, the choice of cutting fud is not pale, the surface of the paper hande not clean when installing the ammonium or there are most injuries on the cone surface
4) when the fat is of the cone handle soft and loaded no the spindle of the machine Io the cone handle is inferred by the come hande, the spindle bent or the spindle bearing to lose o damaged.
5) less liable than the knife floating. not n line with the workpiece hand raring when the force is not uniform so that the reamer let and light swing.
Solutions:
1) According to the tech Station reduces the outer diameter of the recent.
reduce the cutting speed, adjust the fed or reduce the machining allowance reduce the man duration Ange straighten or scrap bending can not be used ammonium knife.
2) careful dressed with whetstone 10 qualified, control swing on the allowed range, hoosmo cutting huid with better cooling performance.
31 before installing the reamer, the oil Inside the tapered handle of the reamer and the taper hole of the spindle of the machine tool must be cleaned and po shed with the oil stone.
4) find hat tal of reader adjust o space spindle baing. tea dust lasting chuck,
and adjust caiahess to ensure correct operation.
