不少单位,根据132=12×11=42π+0.053的特殊关系,在丝杠螺距S_丝=12毫米的车床上,加工M6多头蜗杆,成功地采用大、小拖板位移综合分头法。实践证明,对单件或小批量生产简便易行,准确可靠。车削一般的多头蜗杆,均可采用此法进行分头。现以在S_丝=12毫米车床上,车削M6多头蜗杆为例,介绍分头步骤、原理、判别方法和综合分头的数据。一、分头步骤分头时,停车后提起对合螺母,手摇大拖板向回移动(简称“空移”)L=
Many units, according to the special relationship of 132 = 12 × 11 = 42π + 0.053, machined M6 long worm on the lathe with screw pitch S_share = 12 mm, and succeeded in adopting the comprehensive split method of displacement of big and small carriage. Practice has proved that a single or small batch production is simple, accurate and reliable. Turning the general long worm, can be used this method separately. Now in the S_ wire = 12 mm lathe, turning M6 long worm, for example, introduced the separate steps, principles, methods of identification and integrated data. First, step by step separate, filed after the stop on the nut, hand the big board back to move (referred to as “empty shift”) L =
