Problems solved by technology

At present, most of the CNC blades used in CNC machining centers are imported blades. Although the performance is superior, the cost is very high, and there may be problems such as long delivery cycle or unstable supply, and lagging after-sales service.
[0003] For a long time, because of its complex production process and high requirements on production equipment, CNC inserts have high added value. At present, only a few large cemented carbide manufacturers at home and abroad can produce products with stable performance, and other small factories are either because of the threshold. Abandoning production if it is too high, or because the quality of the products produced by the workshop is not stable, it may affect the quality and pass rate of the customer's processed products because of the quality of the blade, or even damage the high-precision machining center
