Car cylindrical steps

Later, can be installed on the tool and workpiece in lathe began turning processing. In the processing must be conducted in accordance with the following steps: 1. Choose spindle speed and feed, adjust the handle position. 2. To dao, moving head, make the lathe tool tip contact surface, has to drive to zero. 3. After the knife, dial, is used to adjust cutting depth. When dial, is used to adjust cutting depth, should understand the skateboard in the dial scale value, is each turned a small lattice transverse cutting depth value of the tool. Then according to the cutting depth, calculate the need is the number of turns. C616 lathe skateboard dial in every small scale value is 0. 04mm( The diameter of the change) 。 4. Try cutting. Check whether the cutting depth is accurate. The transverse feed. To accurately and rapidly control the turning workpiece cutting deep, must be adept at using the skateboard in the dial. The skateboard in the dial in a horizontal screw shaft end, skateboarding and horizontal screw nut fastening together. Because there is a certain gap between the screw and nut, into scale must be slowly to dial to the number of required. If the dial handle shook his head, or the discovery after trial cut too small in size and must be return, in order to eliminate the gap between screw and nut, should be reversed and a half weeks, then transferred to the required scale value. 5. Longitudinal automatic car into cylindrical. 6. Measuring cylindrical size. And measurement of knife, is the essential means to control the size accuracy, is the basic skill of lathe operators, must grasp skilled.
