The application of mirror spark machine mould manufacturing

As the mold precision and smooth finish demand is higher and higher, mold manufacturing process for improving the application of mirror spark machine, processing requirements of & plusmn; 2 - 3 microns, the bottom corner R value demand less than 0. 3 mm, low to Ra0 processing surface roughness requirements. 3 microns, and even for mirror processing. Mould mirror spark machining precision, fully benefit from the increase of precision CNC edm machine. Because of using ordinary edm machine tool for processing, precision processing precision is not better than, mirror spark machine. General electric discharge machine is difficult to competent for complete precision mirror spark machining, choose good discharge is the prerequisite of the machining accuracy of the machine. Machine tool rigidity, short C shape design to ensure the accuracy of discharge gap; Shaddick pulse power supply can realize small gap under the condition of stable processing; X, Y, Z dc motor driver to ensure the high precision positioning, high-performance servo control system can control the depth of processing error in a minimum of achieve high precision processing; Rich translation methods used for accurate compensation type surface contour; Finishing of electrode loss is small, finishing module meets the demand of mirror finishing, can work out high quality surface; CNC automatic processing and machining accuracy is greatly reduced dependence on human. The improvement of machining efficiency. Modern mould requirements mirror spark machining on the premise of guarantee accuracy increase efficiency of the rough and finish machining. Such as mobile phone shell mold, household appliances plastic mold, optical mirror die mold, medical equipment, electronic instruments, etc, will require large workpiece greatly shorten the discharge time, at the same time, to reduce the roughness. Some mould require no longer manually polishing treatment after discharge, it not only shorten the processing time and dispense post-processing of trouble, while increasing the quality of the mould. The requirement of the efficiency of nc edm machine put forward higher requirements, the performance of automatic programming system to strengthen the processing conditions of retrieval functions, can be more than the switching period of processing conditions, by using the multistage process conditions of the switch, can carry out the conditions of the optimum machining allowance, can shorten the processing time, improve the machining accuracy. The high efficiency of nc edm machine mould enterprises to expand the market space, improve market competitiveness of the capital, the development of new products, new technologies are increasingly popular. The improvement of automation degree. The current advanced CNC edm machine tool automation with improving performance. Some large enterprises of high-tech products has achieved the whole mirror spark machining as long as the electrode loaded before processing knife library, good processing program, can automatically run, using benchmark ball and measuring head positioning, processing of automatic measurement and correction of the electrode and workpiece position, monitoring and processing, no need manual operation, broke the traditional processing tedious operation mode, so automation performance reduces the labor intensity of operators, improve the production efficiency, but also improved the precision of mould processing. New CNC edm machine is mostly used intelligent control technology. As the requirement of market to the mirror spark machining, intelligent technology is also in constant upgrade. Automatic programming system adopts the man-machine dialogue mode, the process of programming, as long as the steps to create the relative zero under the orders of the system, create a location, create a discharge machining can be achieved automatically generated, without any code memory. During processing by the computer monitoring to determine the status of mirror spark machining gap, changing with the depth of processing to achieve adaptive carried knives, realize intelligent control of machining process. Intelligent degree of upgrading make it easier for machine tool operation, lower technical level requirements for operators. With the development of numerical control technology, numerical control mirror spark machining technology has made breakthrough progress. Under the influence of the developed technology, mirror spark machining machine tool performance obtained the comprehensive improvement. In the face of the market now, edm edm machine manufacturers should continuously improve production technology, improve the processing quality and efficiency of nc edm machine, in this way can edm technology is more developed, nc edm machine occupies a lot of market share in the market.
