从适应生产不断发展的需要出发,为消除因无法取出断在工件中的丝锥或钻头而报废的现象,特设计和试制出 SD—Ⅰ型手提式电火花穿孔机,该机就是专门用来蚀除断在工件中的丝锥或钻头的,加工中,不会损伤工件中原有的螺纹或钻孔,而且工件无需经过退火处理,所以工件仍然保持原有的尺寸精度,丝锥或钻头无论断在哪种金属的工件里,采用本机都能顺利取出。一、装置简介SD—Ⅰ型手提式电火花穿孔机,是一种手提的小型的电火花加工机,由自动进给机构和电气二部份组成。
In order to meet the needs of the continuous development of production, in order to eliminate the phenomenon of discarding the taps or bits broken in the workpieces, SD-Ⅰ portable electric spark perforator is specially designed and manufactured. This machine is specially designed for etching In addition to the broken tap or drill in the workpiece, the processing will not damage the original thread or hole in the workpiece, and the workpiece without annealing, so the workpiece still maintain the original dimensional accuracy, tap or drill no matter where broken Metal parts, the use of this machine can be successfully removed. First, the device profile SD-Ⅰ portable electric spark perforation machine, is a portable small EDM machine, automatic feeding mechanism and the electrical two parts.
