Surfacing, grooving and cutting

A, and facing common facing tool ( Bend or partial knife) And the method of surfacing for both car cylindrical and end face, often use elbow tool and partial knife cutting face. Bend tool is to use the main cutting edge cutting, suitable for cutting large end face. Partial knife cutting face, from the outgoing transport deputy of cylindrical cutting edge cutting, former vice cutting edge Angle is small, the cutting is not enough light in the outward turning end, there isn't this drawback, but the workpiece must be before. Note: (surfacing operation 1) When installing workpiece, to his face and the cylindrical alignment. ( 2) Installing a lathe tool, the tip should strictly on the workpiece center, in order to avoid face appeared convex sets, caused the collapse point. ( 3) The end face higher quality requirements, the last cutting knife should be from the center to the outside. ( 4) Turning large end face, to make tool transverse feeding accurately, it should be big slide plate fastening on the bed, with a small tool rest adjust the cutting depth. Second, cutting groove cutting groove cutting knife. Slotting knife before main cutting edges, two vice cutting edges. Installation slot cutter, its main cutting edges should be parallel to the workpiece axis, the main blade and the workpiece axis of the same height. Cut narrow slot, the main cutting edge width is equal to the groove width, transverse feeding groove cut out at a time. Cut wide groove, the main cutting edge width less than the groove width, transverse feeding point several times, cut out of the groove width; Cut out of the groove width, longitudinal feed car tank bottom, cut the wide groove. Three, to cut off the parting tool and grooving knife basic same, but its main cutting edge is narrow, longer of the cutting tools. In cutting process, the cooling condition is poor, cutting tool low stiffness, therefore must reduce the cutting parameter, to prevent the vibration of the machine tool and workpiece. Cut off the operation notice: 1. General use chuck clamping workpiece when cutting. Cut off the place should be close to chuck, lest cause the workpiece vibration. 2. When installing the cutters, point to aim at the workpiece center, tool holder, perpendicular to the workpiece axis tool rod can't stretch out too long, but must ensure that the cutting tool rest don't touch the chuck. 3. Should be lower cutting speed, cutting and should minimize the spindle and the tool rest fitting clearance of sliding parts. 4. Manual feed uniformly. Fast cutting, should feed a little slower, so as not to break of the cutting tools. 5. When cutting steel, need to add cutting fluid.
