Computer gong processing process and matters needing attention in computer gong processing

In order to improve the efficiency of the company, ensure the delivery of parts, and unify and standardize the operating methods, the computer gong processing manufacturers have formulated some relevant regulations, that is, the computer gong processing process and the computer gong processing precautions to be shared with you today, so that everyone can enter faster Working status, improve work efficiency. The first is to determine the processing route, pay attention to the daily cleaning and maintenance of the machine tool, and operate the computer gong machine correctly. 1. Clamping method and tool usage standard before processing: 1. Bead, vise, magnetic table, fixture, choose the best clamping method according to the applicability of the workpiece. 2. Bead: Pay attention to the cleaning of burrs and iron filings on the plane of the machine and the adjustment of the height of the bead to prevent the knife arm from colliding with the bead. 3. Vise: Pay attention to the cleaning and clamping force of the fixed surface and movable surface of the vise. 4. Magnetic table: When using a magnetic table, you must consider whether the bottom of the workpiece is flat, and the suction surface should be large enough to block the edge of the workpiece by the processing pad. To ensure that it will not loosen during processing. 2. Inspection standards before processing: 1. Centering and copying. After each centering is completed, copy the working coordinate number first, and then recheck whether the distance from the center to the two sides is the same after clearing to ensure the centering and copying. The number is correct. 2. Select the knife, install the knife, set the knife, and copy the Z-axis coordinate number. Select the appropriate tool according to the programming list. Before installing the tool, clean the tool head and nozzle thoroughly. After installing the tool, use a calibration table to check whether the tool has deflection. After the knife is copied, check it again to avoid the wrong knife, which will cause major losses to the company. 3. Transmit the program and start processing: use single block execution before cutting, adjust the transmission speed and feed speed to the slowest, lower the knife at a slow speed, watch the machine display the Z axis margin, check if there is any abnormality, if there is any abnormality Press the pause button immediately, find the cause and solve the abnormality, confirm that everything is normal, and adjust to the appropriate speed to start processing. 4. During the machining process, always pay attention to observe whether there is any abnormality in the machining, the knife is not worn, and the sharpening of the tool should be suspended to ensure normal machining. 3. Mold core processing standards 1. After getting the drawing and the workpiece, first check whether the drawing is consistent with the mold number of the workpiece. 2. Measuring the actual size of the workpiece with a measuring tool. 3. Check whether the direction of water transport and reference angle on the 2D diagram is consistent with the direction on the programming list. 4. Use 400# oilstone to clean the bottom and surrounding burrs of the workpiece, and wipe the workpiece clean with a piece of cloth. 5. Place the workpiece on the clamping tool of the machine, flatten the workpiece plane and perpendicularity and parallelism, and the perpendicularity tolerance is within ±0.015, then fix the workpiece firmly and start the centering, according to the position marked on the programming list The size of the middle and Z-axis hits. (Pay attention to whether the edge finder collides with the workpiece when dividing the center) Input the data of the mechanical coordinates X, Y, and Z into the corresponding coordinates. 6. Transfer all the programs into the computer according to the programming list, simulate with the tool path simulation software, observe the processing area, the highest and lowest depth of processing, and determine the clamping direction of the workpiece, the reserved position for clamping and the length of the tool. 7. Install the corresponding tool according to the programming list, and automatically enter the tool parameters in the automatic tool setting method. 8. Transfer the program to the machine for processing. Fourth, copper processing standards 1. After getting the program sheet, compare the mold number on the program sheet and the size and quantity of the copper material to find the appropriate copper material. 2. According to the requirements on the programming list, process rough and young men. (Avoid using the wrong material for thick and young. The copper material is marked with a code, 'A' means 'youngThe program is simulated with tool path simulation software to observe the processing area and the maximum and minimum processing depths to determine the clamping direction of the copper male, the reserved position and the length of the tool. 4. The program is transferred to the machine for processing. The workpiece is being processed Be sure to prepare the next work piece to be put on the machine in order to reduce the time for the above preparation work. 5. Template processing standard 6. After the work piece is processed, visually check whether the shape of the work piece is consistent with the shape of the 3D drawing before getting off the machine, and then check the work piece Whether there is missing processing, over-cutting, and smooth position of the junction. 7. Compare the data marked on the programming list, use a calibration meter or depth meter to measure the accuracy, and measure some matching positions and positioning points with a needle gauge or a plug gauge 8. Test the parting surface: According to the drawings or the data provided by the programmer, detect the coordinates of several points (X, Y, Z) on the parting surface, and check whether the parting surface has been processed to the number. 9. Measure all Whether the horizontal depth is up to the number, for some positions that need to be connected, you need to improve the processing first, paint the color on the connected position, and then slowly connect. 10. Check all other position data that requires CNC machining accuracy, and confirm OK. Get off the machine. 5. Precautions for computer gong processing: 1. Take extra care when removing the tool from the tool holder to avoid scratching your fingers. 2. When using an untested CNC program, do not allow the machine to run fully automatically. 3. When the rotating shaft is still rotating, you need to be very careful to adjust the coolant flow direction. 4. In case of emergency, press the red emergency switch on the controller. The computer gong processing flow and the computer gong processing precautions are specifically shared above. Hope to share with you Help, for those skilled in computer gong processing, it can also be used as a reference.
