Causes solutions for deviations in vertical machining centers
The reason why the vertical machining center will be biased in the actual operation is that there are guide rail errors, fixture errors and table errors in the machining center itself, so there is inevitably a deviation in precision, and in the process, the processing technology and quality The requirements are different, so how should we solve the vertical machining center deviation phenomenon?
1. Optimize the processing technology of vertical machining center
The vertical machining center's process has a direct impact on efficiency and machining accuracy. It ensures the accuracy under the premise of accuracy, so that the process gathers, the road is the shortest, the idle travel and the auxiliary time are the least, which also reduces the error of the burst distance and ensures Azimuth accuracy.
2. Strengthen inspection and maintenance of vertical machining centers and training of operators
The planners select the reasonable processing roads, tools and application sequences according to the type of parts, the differentiation factors, the control processing steps, the order of the work steps, determine the cutting parameters and process parameters, and finally formulate reasonable quality processing procedures; It is necessary to pass the professional training and education, check and pass the qualifications to get a job, to have advanced training and quality understanding, to lengthen the experience and to clean up the simple shortcomings.
3. Optimize the programming procedure of the vertical machining center
When processing a plurality of workpieces of different shapes, it is required to complete a plurality of different sequence actions, and it is possible to complete a plurality of machining operations with only one program, simplifying the programming and improving the power; and using the dry running function to verify the correctness of the walking track, After inputting the program into the machining center, install the tool or workpiece to drive the air running. At this time, the spindle does not rotate, and the worktable is actively operated. This way, it is possible to check whether the visiting tool will collide with the workpiece or the fixture; it must be in the machining center. Set the reference point, and the homework coordinate system and programming should be consistent, and the tool length should be set correctly, otherwise the shortcomings of the bump will occur.
