CBN materials can be used for high-speed cutting or grinding, regardless of the tool or the grinding tool, to achieve significant results such as improved product quality, improved machining efficiency, shorter cycle times and lower processing costs. Therefore, in the processing, the promotion of CBN knives (grinding) is a powerful measure to improve manufacturing technology. However, if it is widely used, there are still many problems.

In order to better promote the use of CBN knives (grinding) in production, the following aspects should be done:

1. Play the leading role of CBN knife (grinding) research institute
At present, there are many domestic CBN material manufacturers, and the output is also quite a lot, but the quality is not much, and the CBN knife (grinding) has fewer stable users. The main reason is that the mechanical processing department lacks the knowledge of the selection and use of expensive CBN knives. The purchased CBN tools are not effective, and under the conditions of economic contraction, they are not easy to invest in process testing. In order to solve this problem, only the CBN Knives Institute will take the initiative to go deep into the production unit of mechanical manufacturing, select the weak link of production efficiency and quality, and have the point of having or easy to create CBN processing conditions, and negotiate with the user. Signed a joint development CBN application contract. The tool development unit is responsible for providing the CBN knife (grinding) for testing free of charge. The user is responsible for providing the tissue production test under the conditions required for the test. This has exerted a lot of enthusiasm. From CBN quality selection to tool manufacturing, it will be carried out at the optimal and fastest speed. From the preparation of test conditions to the use of the user, the user can see the achievement of the target value of the contract and solve it without spending the test fee. Production problems are easy to promote. The tool institutes can also gradually recover profits in future supply. As long as the two sides maintain mutual benefit and mutual benefit, the cooperation relationship will be further consolidated. Our factory has developed many new technologies with many research institutes (schools) in this way.

2. Realize the joint development of three points and one line, that is, CBN--tool manufacturing--user or CBN and tool manufacturing--machine tool--users jointly develop CBN application
The reasons are manifold, such as CBN quality, content, brand specifications and bonding agents are suitable for the processing of boron cast iron. As for the grinding effect of the CBN abrasives, there are more factors. In addition to the quality, proportion and abrasive manufacturing technology of the raw materials, there are conditions and techniques for use. Such as grinding speed (application of high-speed grinding speed), good rigidity of the grinding machine, no vibration, automatic fine feed and dressing compensation mechanism, appropriate grinding parameters and coolant, etc. These are all important factors that complement each other. Working together to improve the quality of their own products and promote each other, CBN tools and special equipment can be successfully used in production.

3. Actively carry out research on manufacturing and using technology of CBN knife (grinding)
Users want to use effective CBN tools. To this end, tool manufacturing units are required. In addition to improving the manufacturing technology of CBN tools as soon as possible, they should also establish clear identification standards and methods for product quality, and distribute certain performance parameters, such as tool CBN. Content and brand, hardness of abrasive tools and CBN precision, concentration, etc., on the basis of production and use tests, in order to give full play to the user's production experience, compare the different cutting parameters and the processing results obtained by the coolant, so that CBN tools have been improved in quality. The scope of CBN tools, the conditions of use and the technical support of the application (such as equipment and coolant), users can choose and use CBN tools correctly.

4. Users need to improve product quality awareness and courage to improve manufacturing technology
The 21st century is a high-tech era. Products must have high performance and high quality to have a market, and enterprises can have vitality. To this end, the level of manufacturing technology should be improved as soon as possible, and the promotion of the use of CBN tools to improve manufacturing technology is a powerful measure, which not only requires strong funding and support from relevant authorities, but also systematically and systematically promotes the technical support of CBN tools. Use, but also requires users to accept new materials, new technologies, change the old obsolete production concepts and management methods, that is, the knife (grinding) has a low cost index, which can only account for about 1/100 of the cost of the product, instead of In order to improve production efficiency and ensure product quality, this will limit the use of high-quality and efficient knife (grinding) tools and advanced equipment production capacity. Practice has proved that the effectiveness of CBN knives can not only improve the processing quality of products, but also improve economic efficiency.
