High speed machining has been widely regarded as the processing technology to increase production and reduce manufacturing cost. The concept of dry machining or micro lubrication is now the main goal of the industry to reduce environmental and production costs. Productivity is the most important factor for tool manufacturers and suppliers. Cutting performance (cutting speed, unit time cutting) increased by 20%, manufacturing costs will be reduced by 15%. More stringent machining requirements require further development of cemented carbide cutting tool materials and coatings to improve machining conditions and improve tool design.

From the current situation, domestic cemented carbide indexable tool market share is lower than the import tool, the reason mainly has the following several points: 1 the quality of the products do not have a strong sense of some domestic tool producers lack of adequate quality consciousness. The quality of the indexable inserts in China is poor, the varieties are few and the specifications are incomplete. From the appearance quality of the product, the appearance, color and texture of the imported tools are superior to the domestic ones. In the performance of the products, compared with the domestic tool, machining tool imports of high precision and good stability, high durability, high removal rate, tool and accessories have good interchangeability, the general assembly can achieve the precision. 2 pre-sale customer service service is not perfect in many foreign companies have tools for users including tool selection, supply, adjustable, timely replacement and thoughtful service, and many domestic tool manufacturers in this regard is not doing enough, simple and extensive service. 3 small workshop production still accounts for a large proportion due to economic reasons, some domestic tool manufacturing plant small workshop production still accounts for a large proportion, low level of processing technology, simple equipment, to ensure product quality. It is difficult to eliminate the quality problems of the tool products by the machining quality and assembly quality.

Recent data concludes that he tool material has entered the era of development with hard alloy represented, compared with high-speed steel, cemented carbide has better performance and higher cutting efficiency, and super hard materials, is an important guarantee for the efficient processing of modern cutting technology. There is no good tool material, any tool innovation and cutting processes are the lack of the necessary material basis. To solve this problem fundamentally, will involve the industry structure adjustment, speed up with hard alloy material and tool research and development capabilities of the production base of the construction process, the rapid increase of cemented carbide cutting tools account for the proportion of all cutting tools.

Matters needing attention

1, the proportion of cemented carbide material, therefore, the size and quantity of large, need special attention, should be treated as heavy objects.

2, carbide cutting tools in the grinding process will produce higher cutting temperature and dust, aerosol. When the dust, mist contact with eyes or skin, as well as by the human body will be harmful.

3, cemented carbide cutting tools for grinding, it is recommended that you use a local dust collector, with masks, eyes and gloves and other protective measures. If the hands are stained with dust, wash thoroughly with soap and water.

4, do not work in the dining room, the meal should be washed clean. Application of vacuum cleaner or washing method to remove the dust on the clothes, do not hand beat dust.

5, repeated or long-term exposure to dust will affect the skin, respiratory tubes and heart.
