What are the operating conditions of ordinary lathes?
The normal use of ordinary lathes must meet the following conditions: the power supply voltage fluctuation at the location of the machine tool is small, the ambient temperature is less than 30 degrees Celsius, and the relative humidity is less than 80%.
1. Environmental requirements for machine location
The location of the machine tool should be far away from the source of vibration, direct sunlight and thermal radiation, and humidity and airflow should be avoided. If there is a vibration source near the machine tool, an anti-vibration trench should be set around the machine tool. Otherwise, it will directly affect the machining accuracy and stability of the machine tool, and cause poor contact of electronic components, failures, and affect the reliability of the machine tool.
2. Power requirements
Generally, ordinary lathes are installed in the machining workshop. Not only the environmental temperature changes greatly, the use conditions are poor, but also there are many kinds of electromechanical equipment, resulting in large fluctuations in the power grid. Therefore, the place where the ordinary lathe is installed requires strict control of the power supply voltage. The power supply voltage fluctuation must be within the allowable range and remain relatively stable. Otherwise it will affect the normal operation of the CNC system.
3. Temperature conditions
The ambient temperature of an ordinary lathe is less than 30 degrees Celsius, and the relative temperature is less than 80%. Generally speaking, an exhaust fan or air cooler is arranged inside the numerical control electric control box to keep the electronic components, especially the central processing unit's working temperature constant or the temperature difference changes little. Excessive temperature and humidity will reduce the life of the control system components and cause more failures. The increase in temperature and humidity and the increase in dust will cause adhesion on the integrated circuit board and cause short circuits.
4. Use the machine tool according to the instructions
When using the machine tool, the user is not allowed to change the parameters set by the manufacturer in the control system at will. The setting of these parameters is directly related to the dynamic characteristics of each part of the machine tool. Only the value of the gap compensation parameter can be adjusted according to the actual situation.
The user cannot change the machine tool accessories at will, such as using a hydraulic chuck beyond the specification. When setting up accessories, the manufacturer fully considers the matching of various link parameters. Blind replacement causes mismatch of various link parameters and even unexpected accidents. The pressure of the hydraulic chuck, hydraulic tool rest, hydraulic tailstock, and hydraulic cylinder should be within the allowable stress range and any increase is not allowed.
