What are the skills in the selection of the storage capacity of the CNC machining center? What should be paid attention to when testing the tool of the CNC machining center?

CNC machining center manufacturers for the same specifications of machine tools, usually set 2-3 different capacity of tool, such as horizontal machining center tool capacity of 30, 60, 80, vertical machining center has 16, 24, 32 capacity of the tool.

Users in the selection, can be processed according to the results of the process analysis of the workpiece to determine the number of required, usually to the need for a part in a clamping tool number to determine the capacity of the tool library, because for another part processing, the need to rearrange the tool, otherwise the tool management is complex and prone to error.

From the statistical data, vertical machining center to choose about 20 knife knife library, horizontal machining center to choose about 40 knife knife library is appropriate. Of course, according to the actual need to determine. For the machining center machine tool of flexible manufacturing unit (FMC) or flexible manufacturing system (FMS), the tool store capacity should be large capacity tool store, or even configured with exchangable tool store.

CNC machining center knife storage capacity selection is very important, but the test knife is also a process of workpiece processing, in this process to pay attention to what?

1, machining center when the tool moves to the surface of the workpiece 30-50mm, must confirm the residual axis axis and X, Y axis coordinate values in keeping with the feed while consistent with the mode.

2. For some tools that require testing tools, use the "progressive" approach. For example, you can test the length of the borehole. After passing the test, the full length can be reached. Tool data using the tool radius compensation function can be modified from large to small.

3, in the process of machining center trial cutting and processing, after the replacement of the tool, be sure to re measure the tool length and modify the tool compensation value and tool compensation number.

4, the program search should pay attention to the cursor pointing to the position is reasonable, is accurate, and observe the tool coordinates and machining center movement direction is correct.

5, modify the machining center program, must carefully calculate and carefully check the modified parts.

6, the execution of manual feed and manual continuous feed operation, need to check whether the switch selected position is correct, find positive and negative direction, and then press the button before the operation of the machining center.
