ZM705Z型硬质合金刀片研磨机是我厂精加工硬质合金刀片的关键设备,但常出故障,平均每季更换一次下主轴下端的蜗杆、蜗轮及两个角接触球轴承,维修费用达3000多元。 故障主要原因是研磨混合液浸入,造成零件磨损。如图1所示,研磨混合液从机床上方研盘流到箱体裙边1上,再由橡胶刷2将其扫入箱体回流 ZM705Z type carbide blade grinding machine is the key equipment of our factory finishing carbide blade, but often fails, the average quarterly replacement of the lower spindle under the worm, worm and two angular contact ball bearings, maintenance costs up to 3000 Multiple. The main reason is the failure of grinding mixture immersed, resulting in wear parts. As shown in Fig. 1, the grinding liquid flows from the grinding machine on the top of the machine to the skirt 1 of the box body, and then is swept back into the box body by the rubber brush 2
