What should be paid attention to when clamping workpieces using CNC milling machines

1. The equal-height iron used for clamping must be ground by a grinder to make it smooth and flat.

2. The code iron and nut must be strong and can reliably clamp the workpiece. For some small workpieces that are difficult to clamp, they can be clamped directly on the tiger;

2. The machine tool workbench should be clean and free of iron filings, dust and oil;

4. The shims are generally placed at the four corners of the workpiece. For workpieces with too large a span, equal-height shims must be placed in the middle.

5. According to the size of the drawing, use a ruler to check whether the length, width and height of the workpiece are qualified.

6. When clamping the workpiece, according to the clamping and placement method of the programming work instruction, consider avoiding the processing area and the situation where the tool head may hit the fixture during processing.
