1. Basic knowledge:
1) Pay attention to measuring the size of the clamping tool to prevent collision with the machine tool. The safety distance must be kept between 15MM and 20MM
2) Clean and maintain the machine once every two weeks
3) Establish procedures and use procedures in accordance with "CNC Procedure Management and Use Regulations"
4) When the tool is installed in the collet, ensure that the surface of the tool and the inner wall of the collet are clean and free of foreign matter, the collet is suitable and does not scratch the inner wall of the collet. If there is a collet with a scratch on the inner wall, it should be reported in time
5) Before starting the machine, the oil filter must be turned on, especially when going to work after a weekend break and after a power failure
6) Follow the shutdown procedure to shut down step by step. Shut down step by step is strictly prohibited. Shutdown steps: save the program, turn off the program, turn off the computer, turn off the computer power, turn off the CNC power supply, turn off the regulator switch, turn off the exhaust fan switch, turn off the oil filter switch and Its air-conditioning switch, turn off the main power switch
2. Skills:
1) About shaking knife
A. Choose the right grinding wheel
B. Choose the correct grinding direction of the grinding wheel, and it cannot be reversed, that is, the cutting edge of the tool cannot be cut with the grinding wheel, otherwise it will be easy to shake the knife
C. Choose a proper feed margin, too much feed margin will cause tool vibration
D. Select the appropriate grinding wheel speed
2) One-time clamping
A. The entire production process of completing the tool in one clamping can greatly reduce the production time of a single tool and improve efficiency
B. In the case of not grinding the chuck, try to clamp as many tool holders as possible
C. If the chisel edge is asymmetrical, consider whether the chuck is OK
D. The tool is too long, consider using support
3) Save machine downtime
A. Use CNC grinding time to rest the grinding wheel/measure the grinding wheel and reduce CNC downtime
B. When the machine tool is running (the time period of the last tool), adjust the program of the next order to reduce the time of CNC shutdown. However, after installing the tool and before running the program, confirm whether the program is used incorrectly. To ensure that the wrong program is not used
4) Select before grinding, the same type of tool is grinding according to the same procedure.
A. According to the original knife manufacturer, choose different grinding methods according to different manufacturers
B. Choose according to the size of the collapse and the position of the collapse: 1, the margin is greater than 1mm, the choice is manual grinding the margin first, or the first line cutting, 2, the 0.5-1mm choice is more for the machine margin to complete, in short, one clamping carry out
5) If it can be processed by hand or reworked, it is unnecessary to rework with CNC
A. If the internal cooling hole is not ground during grinding, CNC grinding is not necessary, and the diversion hole can be manually ground
B. Small R, such as R less than 0.5mm, which is not easy to process on the machine or time-consuming, you can use manual frustration.
