Troubleshooting method of auxiliary device of CNC machine tool
CNC lathes in production, need to use supporting devices. Regular inspection and maintenance are required to ensure the normal operation of the machine.We have introduced several ways to check whether these auxiliary devices are faulty.
The classification of CNC lathes
The shape of CNC lathe is similar to that of ordinary lathe, that is, it is composed of bed, headstock, tool rest, feed system, pressure system, cooling and lubrication system, etc. The feed system of CNC lathes is qualitarily different from that of ordinary lathes. The traditional ordinary lathes have feed box and exchange gear frame, while the CNC lathes directly use servo motor to drive the slide plate and the tool rest through the ball screw to achieve feed movement, so the structure of the feed system is greatly simplified. Generally, it can automatically complete the processing of cylindrical surface, conical surface, spherical surface and thread, but also can process some complex rotary surface, such as hyperboloid.
Positioning accuracy and repeated positioning accuracy of small CNC lathe
The precision index of small CNC lathe can be divided into: positioning accuracy and repeated positioning accuracy; Resolution and pulse equivalent; Index accuracy. Positioning accuracy refers to the continuous level of the actual moving position and the command position of the moving parts of the workbench of the small CNC lathe, and the difference is the positioning error. The factors causing positioning errors include servo system, detection system, feed drive and guide rail errors.
CNC lathes commonly used tool material classification
CNC lathe tool material is divided into many kinds, the need to process the material is not the same, the requirements of the tool is not the same, the higher the hardness of the material will need a stronger hardness of the tool, in order to achieve the required processing effect
