Lathe turning processing skill experience

turning is refers to the lathe processing is a part of mechanical processing. Lathe processing first rotating workpiece in cutting tool turning processing. First used in lathe processing shaft, disk, and other has reverse surface of the workpiece, mechanical production and replacement is the most widely used type of machine in the factory. Turner's skill is not over, the skills of the general lathe work don't demand is too high. Turning on the lathe is used relative to the workpiece the workpiece for machining tool rotation method. Turning processing the cutting can supply first by artifacts rather than tools. Turning is the most basic, the most common measures for the machining of occupies very important position in the produce. Turning is suitable for processing and inversion of surface, most has the inversion can be used on the surface of the workpiece cutting processing, such as table, table cylinder conical surface, end surface, groove, thread and inversion of forming surface, etc. , the first is the tool cutting tool. In all kinds of metal cutting machine tools, lathe is the most widely used type, accounts for about 50% of the total machine tool. Lathe tool is available to turning processing of workpiece, and the available drill, reamer, tap and knurled knife for drilling, reaming, tapping screw thread and knurled operation, etc. According to the technological characteristics, such as the layout and the structure features of different, can be divided into horizontal lathe lathe, lathe, vertical lathe, turret lathe and copying lathe, mostly horizontal lathe. Turning processing in machinery production professional is one of the most widely used, the number of lathe, personnel, processing scale, using the tool, fixture and it's heavy and complicated, so turning processing security skills, is especially important, the key work is as follows: 1, the chip damage and protective measures. Lathe processing all kinds of steel parts on patience is better, what happens when turning scraps plastic curl, sharp margin comparison. When high speed cutting steel formed in red, a long scraps, easy to hurt, often wrapped together on the workpiece, tool and tool rest, so work should often use iron hook clear in time or snap, parking to root out when necessary, but absolutely no hand to wipe out or pulled apart or cause drag mark. To avoid chip damage often adopt chip breaker, manipulation of the chip flow direction method and adding various protective barrier. The method of chip breaker is on the cutting tool grinding chip breaker groove or steps; Choose appropriate chip breaker, choose mechanical card tool. 2, workpiece loading card. In the process of turning processing, due to the workpiece loading card machine, broken or damage the tool and workpiece crashed off under a more hurtful or flying out of accident. So, in order to ensure the safety production of turning, it necessary to especially pay attention to pack card artifacts. For intrusive, the shapes of parts to choose suitable fixture, either three or four jaw chuck claws, special fixture and the main shaft it is necessary to secure the connection. The workpiece to CARDS, CARDS tight, great work piece clamping sleeve are available, and to ensure that the workpiece and cutting force, high speed rotation does not shift, don't fall off and thrown out. Top, center if necessary enhancement of solid. Clamping promptly removed after moving hand. 3, safety operation. Will fully check the machine before operation, admit outstanding before use. The workpiece and tool card to ensure correct orientation, strong strong. Machining process, replacing cutting tools, and measuring the workpiece loading and unloading workpieces, it is necessary to park. Artifacts in rotation may not contact with the hand or use cotton silk is wiped. Difficulty to choose the appropriate cutting speed, feed and depth, no overload processing. Shall not be placed on the surface of the workpiece, head of the head of a bed and bed, fixture and other sundry. Tool to be using the file when moving to a safe location, right in the front, left hand in, avoid the sleeves. Machine tools must have the specialist is responsible for the use and maintenance, other personnel shall not be used.
