Vertical machining center 1580 often has various problems in actual processing and production. In order to better improve the processing efficiency and ensure the processing quality, we have summarized the common problems of the vertical machining center and provided effective improvement methods to facilitate more accurate adjustment of the cutting speed, feed, and depth of cut.
Common problem one: over-cutting of the workpiece
The external reasons for the overcutting of the workpiece are often insufficient tool strength or improper size, while the internal reasons may be irregular operators, improper cutting parameter settings, uneven cutting allowance settings, which lead to too large tolerances, and ultimately cause the workpiece Over-cutting has produced machining errors.
To solve this problem, the margin should be kept as uniform as possible when adding the corner cleaning program, the tool should be used as large as possible, and the SF function micro-scheduling of the vertical machining center can be used to gradually achieve the best cutting effect.
Common problem 2: Inaccurate score
Centering is the step of the machining center to determine the origin. It can be said that the centering step is inseparable for any operation using the machining center. In addition to inaccurate manual operation by the operator, burrs around the mold, non-vertical sides, and magnetism on the centering rod will cause inaccurate centering.
The machining center must first demagnetize the centering bar before centering the mold; manual operations for centering must be repeatedly checked, and the centering should be kept at the same point and height as much as possible; calibration is often carried out to check whether the four sides of the mold are vertical.
Common problem three: collision
There is a saying in the machining center workshop: Good technology is caused by machine collision. Although machine collision is now inevitable, a qualified operator of a machining center should have the ability to control avoidable machine collision factors within the range of avoidance. There are various phenomena that cause collisions, and avoidable factors must be controlled in advance.
Avoidable collision factors include insufficient safety height settings; errors in the tool length and actual machining depth on the cnc program sheet, errors in the depth Z-axis access and actual Z-axis access; errors in the coordinate settings during programming.
Therefore, the height of the workpiece must be accurately measured to ensure that the safety height of the vertical machining center is above the workpiece; the tool on the CNC program list must be consistent with the actual program tool, try to use pictures to derive the program list; the actual processing on the workpiece Measure the depth of the tool carefully, and write clearly the length of the tool and the length of the blade on the program sheet. The actual Z-axis reading must be clearly written on the program sheet. This operation is manual operation and must be repeatedly checked to confirm that it is correct.
The emergence of the vertical machining center has brought the CNC machining efficiency of the machining workshop to a new stage. The use of the vertical machining center requires us to further actively study and be diligent in exploring.
