Oil-electric hybrid CNC bending machine in bending size control method: to avoid cumulative error,
each processing a fold to measure the expansion size; Must be bending machine has bent edge of the product,
the front bending Angle should be slightly less than 90 degrees before the formal addition of the first inspection,
inspection in the process of processing: avoid the choice of different heart of the tool,
before adding a confirm that a die tip in the same line: the folding machine is accurate, there are abnormities need immediate detection.
To avoid the bending machine has been bent edge position, avoid a large Angle position;
Determine the accuracy of measuring tools before processing Oil-electric hybrid CNC bending machine?;
Bending machine according to the precision requirements of processed products,
select the right machine; Choose good processing method and good process arrangement method, simplify the processing difficulty.
Check whether the deflection of compensation cylinder of CNC bending machine is large and can not be completely restored to zero.
Check nc bending machine each bending dead point is not changed. CNC bending machine plate itself changes (thickness, material, stress).
CNC bending machine positioning accuracy is not accurate: proportional valve zero bias value is appropriate,
positioning can not be to the bottom dead point so that can not return.
