          Q:

          Slow silk processing accuracy and factors that affect processing accuracy

          1. The precision of slow wire walking is related to the model of the machine tool and the level of the operator. At present, the precision of the processing industry can reach 0.005mm. 2. Slow wire walking is a kind of numerical control machining tool that uses continuously moving thin metal wires as electrodes to conduct pulse spark discharge on the workpiece, generating a high temperature of more than 6000 degrees, eroding metal and cutting into workpiece. 3. The surface roughness of workpiece processed by slow wire cutting machine can generally reach Ra=0.8 μ M and above, the roundness error, straightness error and size error of slow wire cutting machine are less than those of fast wire cutting machine, so it is widely used....
