The material removal during wire cutting processing occurs due to the influence of sparks on the surface of the workpiece. These sparks are not continuous currents, but brief currents that occur millions of times per second.
2.What is the accuracy of wire cutting processing?
Due to the fact that wire cutting is a very precise machining method, its machining accuracy depends on multiple factors, including process parameters, electrode and workpiece materials, current, pulse interval, distance between electrode and workpiece, etc.
Finer cutting lines and more precise control systems can achieve higher machining accuracy
Generally speaking, wire cutting can achieve an accuracy range of tens to hundreds of micrometers. The machining accuracy of high-precision wire cutting can reach the level of ± 2.5um, even about ± 1um, and the roughness can also reach 0.15-0.2uRa.
It should be noted that machining accuracy and surface quality are often affected by machining speed. Higher processing speeds may lead to a decrease in processing accuracy and a deterioration in surface quality. Therefore, when selecting processing parameters, it is necessary to balance the relationship between processing speed, processing accuracy, and surface quality.
