我厂加工的涨圈研磨隔板(如附图)大而薄,要求平直度高(两面的弯曲不大于 0.2公厘),过去是在机械加工前和机械加工后进行手工校直,但往往达不到要求。后来改用低温时效处理,便解决了这种工件弯曲的问题。加工过程是:在下料后由钳工粗校直,使弯曲保持在3公厘以内,再机械加工 My factory processing ring lap grinding partition (pictured) large and thin, requiring high flatness (both sides of the bend is not greater than 0.2 mm), the past is before mechanical processing and mechanical straightening, but Often fail to meet the requirements. Later switched to low-temperature aging treatment, it solves the problem of bending the workpiece. Processing is: roughing straightening by the fitter after the material is cut, keep the bend within 3 mm, and then machined
