Correct clamping method of CNC gantry machine tool workpiece
When machining parts on CNC gantry machine tools, due to the concentration of processes, the entire process is often completed in one installation. Therefore, attention should be paid to the following aspects of the positioning and clamping of parts.
1) Combination fixtures should be used as much as possible. When the batch size of the workpiece is large and the precision of the workpiece is high, a special fixture can be designed.
2) Positioning and clamping of parts should be considered so as not to hinder the processing of various parts, change of tools and measurement of important parts
In particular, be careful not to collide with the workpiece, the tool and the fixture.
3) The clamping force should be close to the main support point or in the triangle formed by the support points, and it should be close to the cutting part and in a place with good rigidity. Try not to be above the processed hole to reduce part deformation.
