With the rise of CNC machining, everyone can always encounter such
and such problems in the CNC machining process. Then, the analysis of
the reasons for the inaccurate surface accuracy encountered in CNC
machining?
1. The cutting parameters are not reasonable
enough, and the surface roughness of the part will lead to the problem
of inaccurate surface accuracy;
2. The cutting edge of the tool is
relatively blunt and not sharp, which will also lead to the problem of
inaccurate surface accuracy;
3. The main reason is that the tool
clamping is too long, and the clearance of the blade is too long. These
two problems will also lead to the problem of inaccurate surface
accuracy;
4. The main reason is that the chip removal, air blowing
and oil flushing are not good enough. This phenomenon will also lead to
the problem of inaccurate surface accuracy;
5. There is a problem
with the original programming method, and this problem will also cause
the phenomenon of inaccurate surface accuracy;
6. Mainly due to
the burr on the surface of the part, the uneven surface of the part and
the burr will also cause the problem of inaccurate surface accuracy.
In response to the above problems, what are the main ways to improve, to tell you:
1. First of all, the setting of cutting parameters should be reasonable, such as tolerance, allowance, speed follow-up, etc.;
2.
Then the tool operator should check from time to time and replace the
tool regularly to avoid the phenomenon of the tool becoming dull;
3.
When clamping the tool, the operator is required to clamp as short as
possible, and the blade should not be too long to avoid the air;
4. The operator must do a good job of air blowing and oil flushing during the operation;
5. For the lower cutting of flat knife, R knife and round nose knife, the speed and feed setting should be reasonable;
6.
The burrs on the surface of the parts have a lot to do with our
equipment, tools and the way of cutting. All, we need to know enough
about the performance of the CNC machining center to make up for the
edges with burrs.
