How to ensure the quality requirements of CNC machining parts?
The CNC machining center is often used for parts and parts.If you control it well,the processing cost will not disappoint you,but you may be disappointed when you are in the process of operation.How to go What are the quality requirements for CNC machining center?
1 Reasonable knife.The optical knife for processing steel and copper shall be strictly distinguished.The remaining amount of the optical knife should be reasonable,so that the smoothness of the workpiece and the service life of the tool will be better.
2 Before processing,use the calibration meter to check whether the tool is swinging within the allowable tolerance range.The cutter head and the lock nozzle should be blown clean with a wind gun before machining,or wiped with a cloth to install the knife.The accuracy of the workpiece is too dirty.Quality has a certain impact.
3 When clamping,pay attention to see if the name and model of the workpiece and the program are the same,whether the material size matches,whether the clamping height is high enough,and the number of calipers.
4 The program list should be consistent with the direction of the reference angle indicated by the mold,and then check whether the upper 3D picture is correct,especially the workpiece that has been transported with water.It must be seen whether the 3D picture is consistent with the water conveyed by the workpiece.If you are unclear,you should promptly feedback the programmer or find the fitter's master on the 2D drawing to see if the 2D and 3D reference angles are consistent.
5 program orders should be normalized,including model number,name,program name,machining content,tool size,feed amount,especially tool holder safety length,reserved margin for each program,light knife,to be clearly stated The R surface and the plane should be connected smoothly.It should be marked on the program list.The operator should increase the processing by 0.02~0.05MM during processing.If you take a few knives,stop and see if it is connected smoothly.Whether it is a level,if not,then lower it.
6 There must be a 2D or 3D picture on the program list,and the“X length,Y width,Z height”six-sided data should be marked.If there is a plane,the“Z”value should be marked,and the operator can easily detect whether the data is correct after processing.Tolerance data should be noted for tolerances.
7 machine tool processing speed operator must be strictly controlled,F speed and S spindle speed should be properly adjusted to each other,F speed is faster than S spindle,speed adjustment in different areas have to be adjusted.After processing,check the quality without any problem,then you can get off the machine and do a perfect machining.
The above is the point that the Jiexiang CNC Machining Center gives you a summary of the quality requirements for CNC machining parts.These details must not be overlooked if the quality of the workpiece is qualified and meets the requirements.
