Conventional lathe is one of the widely used lathes, accounting for about 65% of the total number of lathes, and it is called horizontal lathe because its spindle is placed horizontally. The main components of conventional lathe are spindle box, feed box, skid box, tool holder, tailstock, light bar, screw and bed. The main features are large low frequency torque, smooth output, high performance vector control, fast dynamic response of torque, high accuracy of speed stabilization, fast deceleration and stopping speed, and strong anti-interference ability.
The normal use of conventional lathe 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, and the relative humidity is less than 80%.
1、Environmental requirements for the location of machine tools
The location of the machine tool should be far from the vibration source, should avoid the influence of direct sunlight and thermal radiation, avoid the influence of humidity and airflow. If the machine tool near the vibration source, the machine should be set up around the anti-vibration groove. Otherwise, it will directly affect the processing accuracy and stability of the machine, will make poor contact with electronic components, failure, affecting the reliability of the machine.
2、Power supply requirements
Generally, conventional lathes are installed in machining workshops, which not only have large ambient temperature changes and poor usage conditions, but also have many kinds of electromechanical equipment, resulting in large fluctuations of power grid. Therefore, the location of installing conventional lathe requires strict control of power supply voltage. The fluctuation of power supply voltage must be within the allowed range and remain relatively stable. Otherwise, it will affect the normal work of CNC system.
3、Temperature conditions
The ambient temperature of the conventional lathe is lower than 30 registers, and the relative temperature is less than 80%. Generally speaking, the internal CNC electric control box is equipped with exhaust fan or cooler to keep the electronic components, especially the central processor, working at a constant temperature or with little change in temperature difference. Excessive temperature and humidity will lead to lower life of the control system components and lead to more failures. The increase in temperature and humidity, the increase in dust will produce bonding in the integrated circuit board and lead to short circuit.
4, according to the provisions of the manual to use the machine
Users are not allowed to change the parameters set by the manufacturer within the control system when using the machine tool. The setting of these parameters is directly related to the dynamic characteristics of the machine components. Only the value of the gap compensation parameters can be adjusted according to the actual situation.
Users are not free to replace machine accessories, such as the use of hydraulic chucks beyond the provisions of the manual. The manufacturer in setting accessories, fully consider the matching of the link parameters. Blindly replace the link parameters caused by the mismatch, or even cause an accident that was not estimated. The use of hydraulic chucks, hydraulic tool holders, hydraulic tailstock, hydraulic cylinder pressure, should be within the allowable stress range, do not allow arbitrary increase.
