我们在Y7520W螺丝磨床上磨制程序控制立式铣床的滚珠丝杠(图1)时,由于该机床砂轮修整器不能修整磨制滚珠丝杠的双圆弧砂轮。我们按机床情况和生产要求,设计了一种偏心轴插销定位的双圆弧砂轮修整器(图2)。生产使用证明,达到了技术要求(见图1)。工具的结构简单;使用和装卸方便。 When we grind the ball screw of the program-controlled vertical milling machine on the Y7520W screw grinder (Fig. 1), the machine can not be used to grind the double-curved grinding wheel that grinds the ball screw. According to machine conditions and production requirements, we design a double-arc eccentric wheel shank positioning arbor wheel dresser (Figure 2). Production and use of proof, reached the technical requirements (see Figure 1). The structure of the tool is simple; easy to use and easy to load and unload.
