            ZCCCT Tools Application in Auto Balance Bridge Machining

            Date:2020/04/15

            With the ever-increasing requirements of customers for heavy vehicle performance and applicability, automotive enterprises have accelerated product upgrading pace and product components structure becomes more complex. Balance support is one of such parts, with complex bracket shape structure, and certain difficulty in machining.


            The material of the auto balance bridge in this paper is ZG270-500 (HB180-260), with  complex appearance, high machining difficulty. The following introduces the cutting tools and related recommended cutting data applied in product processing. Different parts of the same type operation are not repeated.
