With the rapid development of modern industry, CNC machine tools are widely used in various fields.
Quite a lot of users think machining accuracy is guaranteed when buying a CNC machine tool, but they do not know the high accuracy of CNC machine tools is ultimately guaranteed by the accuracy of the machine tool itself.
The machine accuracy can be divided into geometric accuracy, positioning accuracy and cutting process accuracy.
After adjustment, geometric accuracy changes little if there is no relocation or large collision accident.
Cutting processing accuracy is essentially a comprehensive reflection of processing geometric precision and positioning accuracy under cutting conditions.
Thus, the CNC machine tool periodic accuracy testing is mainly positioning accuracy testing and error compensation.
Experience shows that 80% machine tools that have been put into production after a period of time will in the working state with abnormal performance, or even beyond its latency affordability.
Usually, new machine tools need to be tested after six months, after which can be tested once a year.
Therefore, regular periodic precision measurement and error compensation for CNC machine tools are critical to reasonably reduce production costs for enterprises, improve the quality of parts processing, reduce waste product, improve the utilization rate of CNC machine tools and extend their service life.
Types of machine tool detection
They include metal cutting machine tools such as CNC lathe, CNC boring machine, CNC milling machine, CNC drilling machine, CNC grinding machine, CNC broaching machine, CNC inserting machine, CNC planer, CNC sawing machine, gear processing machine, screwing and threading machine, machining center etc. and all kinds of special machine tools, ball screws, etc.
Testing projects of machine tool
Positioning accuracy of linear and rotating shaft are reverse error, positioning accuracy, repeatability and position deviation etc.
Geometric accuracy of machine tools is straightness, angle, perpendicularity, flatness and parallelism etc.
