双金属螺母广泛用于大中型机床上。在设备使用过程中,经常遇到双金属螺母严重磨损,无法更新的问题(因离心浇铸困难,一般厂家不能自制)。五年前,我厂B220重型龙门刨床上的双金属螺母损坏了,为了解决这一困难,我们采用钢体与铜套压配,再用螺钉加粘结剂固定的工艺方法,成功的自制了该机的双金属螺母。经五年多使用证明:效果良好,机床 Bimetal nuts are widely used in large and medium-sized machine tools. In the process of using the equipment, often encountered bimetallic nut serious wear and tear, can not be updated (due to centrifugal casting difficult, manufacturers generally can not be made). Five years ago, the bimetallic nut on the B220 heavy duty planer planer was damaged. To solve this problem, we adopted the method of fixing the steel body and the copper sleeve, fixing the technique with the screw and the adhesive, and succeeded in self-made The machine’s bimetal nut. After more than five years to prove that: the effect is good, machine tools
