The processing of steel and copper knives
should be strictly differentiated. The remaining amount of the optical knives
should be reasonable, so that the smoothness of the workpiece and the length of
use of the knives will be better.

2. Before cnc processing, use the
calibration meter to check (check and test) 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 cleaning, or wiped with a cloth to install
the knife. Too dirty is a certain influence on the accuracy and quality of the
workpiece.
3. When clamping, pay attention to see if
the name and model of the cnc machining workpiece and the program list are the
same, whether the material size matches, whether the clamping height is high
enough, and the number of calipers is used.

4. The CNC machining program list should be
consistent with the reference angle indicated by the mold, and then check
whether the upper 3D drawing is correct. Especially for the workpiece that has
been transported with water, it is necessary to see the 3D drawing and the
workpiece water conveyed. Is it consistent? If there is any unclear, please
promptly feedback the programmer or find the fitter master to view the 2D
drawings and see if the 2D and 3D reference angles are consistent. To change
the shape and size of the part, you only need to modify the part processing
program, which is suitable for new product development and modification.

5. The program list of the CNC machining
file should be normalized, including the model number, name, program name,
machining content, tool size, feed amount, especially the tool clamp safety
length, the reserved margin for each program, and the light knife. It should be
clearly stated that the R surface and the plane should be connected smoothly. It
should be indicated on the program list. The operation controller should
increase the processing by 0.02-0.05MM during processing. If it is a few
knives, stop it and see if it is connected. , touch the hand to see if it is
up, if not, then lower it.

6, before processing, you must understand
the contents of the CNC machining program, the program must have 2D or 3D map,
and must be marked; X length, Y width, Z height; six sides of data. If there is
a flat surface to be marked, the operator can easily detect (check and test)
the data after processing, and the tolerance data should be indicated.
7. The machine tool processing speed
operation controller should be strictly controlled. The F speed and the S
spindle speed should be properly adjusted with each other. When the F speed is
fast, the S spindle should be accelerated. The feed speed must be adjusted in
different areas.

No matter the precision and precision of
the cnc machining center, there may be problems with the quality of the
machined workpiece. In this case, don't panic. Only find the real reason to
make a solution.
