China has become the world’s manufacturing center and the largest market for cutting tools. During the 11th Five-Year Plan, domestic tools accounted for over 65% of the market share, but these products primarily fall in the mid to low-end categories, necessitating significant imports of high-grade tools. In 2010, China\u2019s tool consumption was about 33 billion yuan, with approximately 11 billion yuan spent on imported high-grade tools, while domestically developed high-grade tools accounted for only about 1 billion yuan in sales. This situation results in a significant consumption of tungsten resources with low added value.<\/p>\n
Developing high-grade carbide\u00a0tools is crucial for reducing tungsten resource consumption and promoting sustainable development. For example, indexable CNC blades not only inherit the features of high-end solid carbide\u00a0tools but also showcase integration in design and manufacturing, excellent chip-breaking designs, and diverse coating options. Compared to solid carbides, indexable blades significantly increase material utilization; for instance, Seco’s DOUBLE OCTOMILL\u2122 has 16 cutting edges, while Iscar’s H400 olive-shaped blade can be used over 10 times.<\/p>\n
Cutting tools often show minimal wear when they reach normal wear standards; directly classifying these tools as waste leads to significant tungsten resource wastage. Advanced regrinding and recoating technologies can remanufacture such tools, allowing them to maintain cutting performance multiple times and thus improving the utilization of carbide\u00a0tool materials.<\/p>\n
Regrinding of carbide\u00a0tools involves classifying regrindable tools based on the extent of edge damage, determining suitable regrinding plans, and completing the process through rough grinding, fine grinding, and edge reinforcement. After rough and fine grinding, the cutting edge may have defects like micro-chipping and micro-cracking. Appropriate edge reinforcement methods can eliminate these defects, increasing edge strength and tool lifespan. Regrinded tools can also be coated again as needed.<\/p>\n
Due to the standardized and modular nature of indexable blades, the regrinding process can also be standardized. Table 1 outlines the main regrinding processes and characteristics for indexable blades. After proper regrinding and recoating, the cutting performance of carbide\u00a0tools during rough machining is about 50% to 80% of new tools, while during finishing, it is about 85% to 90%. Through advanced regrinding and recoating technologies, carbide\u00a0tools can repeatedly demonstrate their cutting performance, thus enhancing material utilization and reducing tungsten resource consumption.<\/p>\n
