线切割锥度加工实例（Example of taper machining in WEDM） The method of CNC low speed WEDM machining taper and skills of NC information network in September 1, 2010 China source: skxox reading: 610 CNC low speed WEDM machine widely used in mold manufacturing industry and all kinds of hard alloy and precision parts machining. High precision taper machining is one of the most important performances of this kind of machine tools. In order to ensure the taper and size of cutting parts meet the processing requirements, technicians must master the method and skills of machining taper. This article takes Beijing Archie Chamfer CA20 CNC low speed wire EDM machine As an example, the cutting steps of taper parts, the correction of taper machining errors and the skills of taper cutting are introduced in detail, which is of guiding significance to actual production. 1 cutting process of taper parts Processing, as shown in Figure 1 (omitted) shown in the die parts, the workpiece thickness of 50 mm, processing taper requirements of 3 degrees. The process of machining the taper parts is divided into 5 parts: the preparation before processing, the programming of taper processing, the beginning of machining, the process of processing and the end of processing. 1.1 prepare before processing (1) starting the power supply of the machine tool and executing the switch on. After starting the machine, you must first perform the operation of each axis to the machine origin. (2) check whether the remaining yarn is enough; if not enough, replace the new silk. (3) according to the precision requirement and process data of the machined parts, the material of the electrode wire and the diameter of the wire should be considered. (4) threading, using the alignment device to complete the alignment of the electrode wire. (5) fastening and looking for the workpiece, although the CNC low-speed wire EDM machining force is small, not like mechanical cutting machine tools to bear a lot of cutting force, but because
