The turning insert market of steel auto parts has been firmly occupied by Japanese and Korean products for a long time. After years of continuous optimization and improvement, HUARUI has finally developed a new WS8135 grade with strong universality, which can not only meet the needs of high-speed turning of auto parts, but also meet the needs of interrupted turning of many parts in order to save steel material and spaces, matching our new GF, GT, GM GR type chip breaker, covers most of the steel turning application range. In the mold and die industry and general machinery industry, in order to meet the efficient and economic needs, give full play to our technical advantages, HUARUI develop double-sided multi edge milling inserts and meet the needs of high-end precision manufacturing of large and medium-sized parts, specially developed the AOKT shoulder milling series with high precision and high surface quality for Europe and America market, taking a new step in the high-end user market cutting tools are widely used in precision machining of pumps, valves, pipe joints, fasteners, pipe fittings and other parts in general machinery. In order to meet the efficient and economic needs of users and give full play to the advantages of HUARUI forming technology, we have developed double-sided multi edge milling inserts: LNGX、ZNMU、SNMX、PNMU、HNMX、XNGX, etc., to meet the needs of high-end precision manufacturing of large and medium-sized parts.
