Operation of CNC machine


As a operator, it is necessary to operate the machine tool to finish the machining job after understanding the requirements of the machining parts, the process route and the characteristics of the machine tools. Therefore, a few key points of operation are arranged for reference.

In order to simplify positioning and installation, each positioning surface of the fixture should have precise coordinate dimensions relative to the machining origin of the machining center.

In order to ensure the installation position of the parts and the consistency of the work piece coordinate system and the machine tool coordinate system in the programming, fixture and parts should be installed in a directional way.

It can be disassembled for a short time to make it suitable for new work piece. Because of the auxiliary time of the machining center are very short, the loading and unloading of the supporting fixture can not take too much time.

The fixture should be opened possible. The space position of the clamping parts can be lower, and the fixture can not interfere with the tool path.

Ensure that the machining program of the work piece are completed finished in the range of spindle working.

For a machining center with an interactive table, because of the movement of the worktable, the up, the down and the turn,the fixture design must prevent space interference between the fixture and the machine tool

Try to finish all the machining programs in once clip. When replacing clamping tight points, special attention must be paid not to damage the positioning accuracy by replacing clamping tight points, and to explain in process documents.

The fixture and the worktable must be within 0.01-0.02MM, and the surface roughness should not be much than Ra3.2um.
