上海第三机床厂生产的M9017光学工具曲线磨床,由于采用干磨工艺,故尘屑飞扬严重,不仅影响工人健康,而且还会加剧导轨等的磨损,失去机床精度,为减少尘屑,该厂给此机床配备了一种吸尘器。此吸尘器如图1所示,采用螺旋离心粘附的办法来吸尘。其工作原理是:鼓风机的进风管伸至产尘区,形成负气压,于是加工时不断产生的尘屑和空气吸入鼓风机,经叶轮4压向圆 M9017 Optical Tool Curve Grinder produced by Shanghai No.3 Machine Tool Plant can not only affect the health of workers, but also aggravate the wear of guide rails and other machines due to the use of dry grinding process, resulting in the loss of precision of the machine tools. In order to reduce the dust, This machine is equipped with a vacuum cleaner. The vacuum cleaner shown in Figure 1, the use of spiral centrifugal adhesion method to vacuum. Its working principle is: Blower into the air duct extends to the dust zone, the formation of negative pressure, so constantly processing dust and air inhaled blower, the impeller 4 pressure round
