JCR CNC Models, is a focus on CNC precision machining enterprises, today to talk about the common problems of CNC precision machining points, how should we avoid and prevent it?
The following are the common problems of CNC precision machining:
CNC precision machining common problem point- - - -overcutting
A, overcutting caused by the cutting problem is due to the flexibility of long tool or other reasons, overcutting in the processing process; B, processing parameters unreasonable equipment, equipment rotation too fast or too large, which is also one of the causes of overcutting
C. Incorrect clamping method is also one of the reasons for CNC precision machining
CNC precision machining common problem point- - - -burr
A, cross hole burr is one of the most troublesome problems of CNC precision processing, the burr of the rear processing hole will certainly turn over the front processed hole, resulting in the residue of the burr, B, the root burr is also a dead corner burr is difficult to solve the problem of CNC precision processing, generally speaking, as far as possible to choose A small tool for Angle;
C, the burr produced by the Angle, there are a lot of parts drawings do not allow the sharp Angle inverted bell, which directly leads to the burr produced by the processed Angle to rely on manual removal, and the risk is very high.
CNC precision machining common problem point- - - -point is not allowed
A, the processed burr will affect the accuracy of the division, resulting in the division, resulting in the scrap of parts;
B. The tolerance of the datum is too large, resulting in inaccurate scores;
C. Operators' error will also cause inaccuracy or incorrect data compensation.
4. CNC precision machining common problem point- - - -deformation
A. The release of material stress will lead to deformation of parts, resulting in poor size and scrap of parts;
B. The clamping method is wrong, resulting in the deformation of the parts and the size changes after the loose clip:
C. the cutting amount is too large, resulting in deformation of parts.
The above problems are the common problems of CNC precision machining. Generally speaking, as long as the technical personnel engaged in CNC precision machining must have encountered these problems, if we are solved
