颤震是金属切削加工中常见,而又难以解决的加工问题,其原因较为复杂,多出现于细长工件的加工。在磨削细长的小销轴时,若用轴类支承架,是难以解决磨削时所产生的颤震。如图所示是一个可以无级调节支承力的支承架。当磨削小销轴产生颤震时,松开抗重6紧固螺钉,向外侧或向里移动抗重,直至颤震消除,再将抗重6紧固。 Tremor is common in metal cutting, but difficult to solve the processing problems, the reason is more complicated, mostly in the processing of elongated workpieces. When sharpening a small pin, it is difficult to solve the chatter generated during the grinding with the shaft support. As shown in the figure is a stepless support for the adjustment of support. When sharpening the small pin shank, loosen the anti-gravity 6 fastening screw and move the anti-weight to the outside or inside until the chatter is eliminated, then tighten the anti-heavy 6.
