The factors affecting the efficiency of brass wire EDM machine
There are many factors that affect the cutting power of the Brass wire EDM machine. If there is a low power situation during processing, you can consider the two elements described below.
(1) The brass wire cutting EDM machine cannot be effectively flushed with high-pressure water due to the limitation of the part structure and clamping
At this time, it depends on whether the parts cut by the machine tool can be improved from the clamping. Some parts are affected by the support fixture and the bottom surface is raised, some parts are affected by the pressure plate and the position of the clamping screw, and the nozzle has to be raised, and the operator is afraid of touching the nozzle and not dropping the upper nozzle to the lowest point. . The condition of the lower surface being raised depends on whether you can choose a fixture with the fixture support surface on the same plane as the work surface, or clamp the workpiece directly on the work surface.
Affected by the screw pressure plate and the parts to see whether the jaw clamp can be used for clamping; if the operator is worried that the upper nozzle is not dropped to the lowest point, a 0.1mm feeler gauge can be prepared as required. If it is true that due to structural limitations, the parts that cannot be effectively flushed with high-pressure water can only reduce the cutting energy, then there must be a correct parameter for the cutting power.
(2) Wire transport system related (related to protection and maintenance)
1) Check whether the cooling water of the conductive block of the wire EDM machine is normal. In particular, whether there is cooling water for the lower conductive block, because copper powder will be dropped during the cutting process, after long-term use of the machine tool, the cooling water for the lower conductive block and even the flushing water for the lower nozzle processing may be blocked, and it should be cleaned and dredged;
2) The rolling of the lower guide wheel on the lower arm is sensitive. Check and clean;
3) Whether the take-up wheel is normal;
4) Check the tension and speed of the silk, and re-condition if necessary;
5) Check and clean the wire guide nozzle and conductive block of the machine tool.
