Lathe processing – computer gong processing

Lathe processing is a part of mechanical processing. There are two main processing forms of computer gong processing: one is to fix the turning tool to process the unformed workpiece in rotation, and the other is to fix the workpiece to carry out precision processing through the high-speed rotation of the workpiece and the horizontal and vertical movement of the turning tool (tool holder).

1. It is easy to ensure the accuracy of each processing surface of the workpiece; during processing, the workpiece rotates around a fixed axis, and each surface has the same rotation axis, so it is easy to ensure the requirements of coaxiality between processing surfaces;
2. The cutting process is relatively stable; in addition to the intermittent surface, generally, the processing process of Dalang lathe is continuous, unlike milling and planing, in the process of one tool feed, the cutter teeth have multiple cuts in and out, resulting in impact;
3. It is suitable for finish machining of non-ferrous metal parts; for some non-ferrous metal parts, because of the low hardness and good plasticity of the material itself, it is difficult to obtain a smooth surface with other machining methods;
4. The cutting tool is simple; turning tool is the simplest one of the cutting tools, which is very convenient for manufacturing, grinding and installation, so it is convenient to select a reasonable angle according to the specific processing requirements

Operation safety of lathe

1. It is forbidden to put on the protective clothing when the machine is operating. It is forbidden to put on the protective clothing when the machine is operating. It is forbidden to put on the protective clothing when the machine is operating. Must wear a helmet, braids should be put into the hat, not to wear skirts, slippers. Wear protective glasses to prevent eye injury caused by splashing iron chips.
2. It is necessary to carefully check whether the machine tool operates safely and reliably according to the requirements of no-load operation for 2 ~ 3 minutes, and carefully check whether the machine tool operates safely and reliably.
3. When loading and unloading chucks and large pieces, check whether there are obstacles around, pad wood to protect the bed surface, and block, hold firmly and frame well. When the car is too heavy, balance should be done according to the weight. The clamping of workpieces and tools should be tightened to prevent workpieces or tools from flying out of the fixture. The chuck wrench and socket wrench should be removed.
4. When the machine tool is running, it is strictly forbidden to wear gloves to operate; it is strictly forbidden to touch the rotating part of the machine tool with hands; it is strictly forbidden to transfer objects across the lathe during the operation of the lathe. The machine should be stopped to load and unload the workpiece, install the cutter, refuel and clean the chip. Brush or hook shall be used to remove iron filings. Hand cleaning is forbidden.
5. When the machine tool is running, it is not allowed to measure the workpiece, and it is not allowed to use the hand to brake the rotating chuck; when using sandpaper, it should be placed on the file, and it is strictly prohibited to wear gloves to operate with sandpaper. It is not allowed to use the worn sandpaper, it is not allowed to use the file without handle, it is not allowed to use the brake of the front and back brake, it should go through the intermediate braking process.
6. The cutting parameters are selected according to the technical requirements of the machine tool to avoid accidents caused by overload of the machine tool.
7. When cutting, the cutter should be withdrawn when stopping. The center frame must be used for machining long axis of mechanical parts to prevent the workpiece from bending and deforming to hurt people; the length of the bar extending into the head of the bed shall not exceed the vertical axis of the head of the bed, and it shall be processed slowly, and attention shall be paid to protection when extending.
8. When cutting at high speed, there should be a protective cover. The workpiece and tools should be fixed firmly. When the iron chips splash seriously, a baffle should be installed around the machine tool to isolate it from the operation area.
9. When the machine tool is running, the operator can’t leave the machine tool. If the machine tool doesn’t work properly, stop the machine immediately and ask the repairman to check and repair it. In case of sudden power failure, shut down the machine immediately and exit the tool from the working position.
10. When working, you must stand sideways in the operating position, and it is forbidden to face the rotating workpiece.
11. At the end of the work, cut off the power supply of the machine tool or the main power supply, withdraw the cutting tool and workpiece from the working position, clean and place the tools, clamps and measuring tools used, and clean the machine tool. Now because the automatic lathe processing market is not perfect and sound, small stamping parts market is very mature in some areas.

From the current situation, there are some problems in the automatic lathe processing market, some production capacity is oversupplied, and some stamping plants in the main engine factory can’t put it or hold it.
