Causes of errors in CNC engraving and milling machine

Troubleshooting of CNC engraving and milling machine error

(1) . use environment

CNC engraving and milling machine is a high-tech mechatronics equipment, which has certain requirements for the working environment.

  1. The voltage should be stable to avoid large fluctuation. It is better to use voltage regulator.
  2. The machine should not work in strong acid and alkali environment for a long time.
  3. Avoid the equipment that seriously affects the signal transmission of engraving and milling machine, such as strong electricity and strong magnetism. Such as welding machine, transmitting tower, etc.
  4. Use three core power supply to ensure good grounding of engraving and milling machine and reduce interference.

(2) 2. Processing problems

  1. Operators

The proficiency and responsibility of operators also have a great impact on the machining accuracy.

  1. Wear and tear of the machine

CNC engraving and milling machine wear is inevitable in the process of use, machine parts processing with the passage of time, machine wear will reduce the accuracy of the machine.

  1. Rationality of processing technology

In addition to the CNC engraving and milling machine to ensure the machining accuracy, reasonable processing technology is also very important. In order to ensure the accuracy of processing, please pay attention to the rationality of processing technology.

  1. Tool use

The machining accuracy is affected by the manufacturing process and accuracy of the tool itself. Therefore, when machining, please select the suitable tool.

(3) . maintenance and maintenance

CNC engraving and milling machine is mostly used in processing business, which produces more powder and dust. Pay attention to keep the screw rod, polished rod and other parts clean and lubricated in use, clean the dust and oil the transmission parts in time; the operator shall clean and oil in time, and it is strictly prohibited to plug and pull with electricity.

(4) . software usage

CNC engraving and milling machine has many engraving and milling software for use. In order to meet your carving and milling requirements, please choose the correct operation software.

  1. The continuous operation time is less than 10 hours per day to ensure the cleaning of the cooling water and the normal operation of the water pump. The water spindle motor must not be short of water. The cooling water should be replaced regularly to prevent the water temperature from being too high. If the working environment temperature is too low in winter, the water in the water tank can be changed into antifreeze.
  2. Every time the machine is used, pay attention to cleaning, be sure to clean up the dust on the platform and transmission system, and lubricate the transmission system (x, y, z axes) regularly (weekly). (Note: the X, y, Z three-axis polished rod shall be maintained with engine oil; the screw rod part shall be added with high-speed grease; if the working environment temperature is too low in winter, the screw rod and polished rod (square guide rail or circular guide rail) part shall be washed and cleaned with gasoline first, and then the CNC machine tool shall be used for processing, and then the engine oil shall be added, otherwise the resistance of the machine transmission part will be too large, resulting in the machine dislocation.)
  3. When the electrical appliances are maintained and checked, the power supply must be cut off. It can only be carried out after the monitor has no display and the main circuit power indicator is off.
  4. After about three months of use, the fasteners should be inspected, and the connecting screws on both sides of the gantry, the fastening screws of the lead screw nuts, and the fastening screws of the motors on both sides should be tightened.
