CNC lathe machining dimensions of the reasons for instability and solution measures
The so-called dimensional accuracy mainly refers to the degree of conformity between the dimensions of the workpiece and the dimensional requirements of the drawings after the completion of machining parts, so, in order to improve the dimensional accuracy of the parts in the operation of CNC machine tools, it is necessary to pay attention to the operating techniques in the operation of CNC machine tools, the dimensional accuracy of the parts of the commonly used methods of controlling the dimensional accuracy of the parts, such as the accurate tool setting, the adjustment of the tool wear compensation and the modification of the dimensional control accuracy in the program. Control accuracy, so that the size of the workpiece produced to be accurate.
1, CNC lathes produce crawling situation
The main reason for the crawling situation of the equipment is that the drag plate guide rail wear is more serious, screw ball wear or loosening. Solution: daily attention to the maintenance of CNC lathe operations, after the completion of the work should pay attention to cleaning wire, and timely filling of lubricants to reduce friction.
2, CNC lathe resonance, placed on the unstable situation
Need to choose the ground smooth position to place the CNC lathe, pay attention to adjust the angle, fixed must be smooth.
3、Processing technology is not good
Select the coolant suitable for workpiece processing, and in the case of processing requirements can be achieved in other processes, or as far as possible to choose a higher spindle speed, so that the parts processed will be particularly clean.
4, the tip of the tool is damaged, or the tool is not sharp
If the tool is not sharp after wear or damage, you need to re-grind the knife or choose a better tool to re-sharpen the knife.
5、Quick positioning speed is faster, the motor and drive can not react, resulting in unstable processing size
If the rapid positioning speed is faster, then you need to properly adjust the speed, cutting back to the speed and time, so that the drive and motor in the rated operating frequency of normal action.
6, the drag plate for a long time to maintain high-speed dynamic behavior, resulting in the wear of the screw and bearing conditions
You can use the percentage meter against the bottom of the tool holder, and at the same time through the system to edit a certain fixed cycle program, in order to check the CNC lathe equipment drag plate repeat positioning accuracy, adjust the gap between the screw, replace the bearings.
According to the Measures for the Evaluation of Science and Technology-based Small and Medium-sized Enterprises (Guo Ke Fa Zheng  No. 115), the Circular of the Ministry of Science and Technology and the State Administration of Taxation on Matters Concerning the Evaluation of Science and Technology-based Small and Medium-sized Enterprises (Guo Ke Fa Huo  No. 11), and the Guidelines for Evaluation Services of Science and Technology-based Small and Medium-sized Enterprises (Guo Ke Huo Zi  No. 67), the province was decided to carry out the 2023 evaluation of national science and technology-based small and medium-sized enterprises. It is decided to carry out the evaluation of national science and technology-based small and medium-sized enterprises in the province (except Ningbo, the same hereinafter) in 2023. The relevant matters are hereby notified as follows.
Five-axis milling and boring machining center process characteristics are determined by the production of the power head, mainly for drilling, tapping, boring, chamfering, milling, grinding and other types of processing to meet the processing needs of most customers. The power head is highly applicable and can be easily adjusted for different sized tools of the same type according to the type of tool used. Power head spindle with high rotary accuracy, good rigidity, no mechanical wear and vibration absorption, etc., suitable for cast iron, steel, non-ferrous metal materials, high machining accuracy can be combined with the stroke of the slide table to control the movement process of the power head, to meet the workpiece of a variety of modeling process characteristics. The guide rail and bed of the hard rail are integrated casting parts, and then the guide rail is processed on that basis, and then processed through quenching, grinding and then processed into the guide rail.
