III. Tungsten carbide cutting tool innovation

The cutting tool innovation is the most important factor for promoting cutting technology and improving cutting efficiency. Modern innovation is this area lies in three aspects as follows:

 

(1) Material grade innovation

It accounts for a large proportion among the cutting tool innovations nowadays. Some large enterprises abroad with the capability to develop and produce tungsten carbide and other super-hard materials will provide many new cutting tool material grades every year to attraction attentions on their new products. They are developed according to the characteristics and requirements in some specific areas and are given the related advantages to improve machining efficiency by over 20%.

 

(2) Tungsten carbide cutting tool coating innovation

Coating technology innovation not only contributes to the cutting efficiency improvement of the cutting tools, but also to the better and faster innovation of the cutting tool coating grades. However, China up to now still lacks the capability to do its own development towards coating equipment and technology. Therefore, to strive to develop cutting tool coating technology is of utmost urgency.

 

(3) Tungsten carbide cutting tool structure innovation

The innovation towards cutting tool structure not only improves the cutting tool property, but also has great effect on the development of cutting tool varieties sometimes.  For example, the milling cutter structure that can do slope milling significantly expands the functions of milling cutters and reduces the blade replacing times. Also, its structure characteristics have been applied in milling cutters of different kinds, which promote the development of milling processing and milling cutters. The emergence of every type of new cutting tool can attract great attention from the whole industry and help the rapid application among it, which is good for the richness of cutting tool varieties and the improvement of cutting tool properties. A large number of tungsten carbide cutting tool enterprises in China only produce cutting tools without putting a bit of efforts on cutting tool materials development and production, thus much more importance should be attached to cutting tool structure innovation in the future.
