Application Of Advanced Cutting Tools To Textile Machinery Engineers

I work in a large state-owned enterprise. Spin Machinery manufacturing enterprises have been established 60th anniversary years ago. Since the beginning of the plant, our company has been developing and producing various kinds of machinery and equipment, especially spinning frame products, which has been sold at home and abroad for a long time. It is necessary to use advanced tools to improve production efficiency and product accuracy, and provide a good foundation for the increasingly diversified processing. This is an important issue facing our enterprises.

Our annual cost of cutting tools is up to about 2000000 yuan. Considering the cost performance and applicability of the tools, we chose Sweden's Sandvik, NIKKEN, Kenna, Zhuzhou and MITSUBISHI. In addition, in the actual production application, according to the accuracy of parts, processing technology and equipment, we also applied other brand cutting tools, such as Austria PLANSEE aluminum cutting tools, the Japanese card cutter, the Japanese OSG drill bit, the Swedish hill high milling cutter and the domestic industrial taps, etc.

The consensus reached in the industry, and after the cutting economic analysis and processing practice, is confirmed by two points: the cost of cutting tools only accounts for 3% to 5% of the manufacturing cost of parts. Therefore, even if the purchase price of tools is reduced by 30%, the cost of manufacturing parts can only be 1%. However, if cutting ability can be improved by selecting excellent tools, and the machining efficiency can be increased by 20% (for example, adopting new tool material grades), the cost of manufacturing parts saved by enterprises can reach 15%. Because the improvement of cutting tool efficiency means reducing the cost of workshop, electricity cost, time cost and labor cost of a single product effectively, thus reducing the average production cost of a single product.

How can we improve the application level of advanced cutters in enterprises? Next, let's talk about the application of advanced cutting tools with the actual situation of our company's cutting tools.

Selection of advanced tool structure

The proportion of indexable tools and coated tools can be increased and the whole cemented carbide tools should be applied. Since our first CNC machining center was introduced from Italy in 1980s, we have been exploring and advancing on the road of using indexable tools and coated tools. Up to now, the ratio of indexable tools and coated tools has accounted for 80% of the metal cutting process in our company. Indexable cutting tools have the characteristics of high efficiency, high speed and high precision. The coated tools have the characteristics of high surface hardness, good wear resistance, stable chemical properties, heat resistance and oxidation resistance. The effective application of these advanced tools laid the foundation for the success of our company's excellent textile machinery equipment.

Our company began to use carbide bits in production very early. In the past, it has been thought that drilling must be carried out at lower feed rate and cutting speed. This view was once correct under the condition of using ordinary drill bits. With the advent of cemented carbide bits, the concept of drilling has also changed. In fact, by selecting the right carbide bit properly, drilling productivity can be greatly increased and the processing cost per hole can be reduced.

According to different processing conditions, our company has three basic types of cemented carbide bits: solid carbide bits, carbide indexable inserts, and welded carbide bits. Each drill bit has its advantages for specific machining conditions.

The application of the whole cemented carbide bit not only improves the production efficiency, reduces the occupation time of the CNC machine tool, but also saves the manufacturing cost of parts in many ways, and because the whole carbide tool has good wear resistance and long life, and also reduces the cost of cutting tools effectively. In the past two years, our company has achieved good results in the application of the whole carbide milling cutter.

　 Adopt new tool material grade

The new tool material brand is adopted to better adapt to the workpiece material and cutting conditions. Adopt new brand of cutting tool material as far as possible, so as to better adapt to workpieces and cutting conditions. The modern manufacturing industry is covered by a wide range of processed materials, including iron and steel, non-ferrous metals and heat resistant alloys, synthetic materials, etc. these materials not only differ greatly in their machinability, but also differ in machinability among different materials, such as ferrite stainless steel and austenitic stainless steel, although they belong to stainless steel, but their machinability is also different. Therefore, if we choose the brand of cutting tool material, we can receive the effect of "prescribe the right medicine". Not only that, users in the face of turning, milling, drilling and other different processing technology and high-speed machining, low speed rough machining and other cutting conditions, we must select the corresponding brand, in order to achieve the desired processing effect.

Usually, the development of a new brand can increase the cutting efficiency by more than 20%. The timely discovery and application of new brands to replace existing brands should be a regular job for our enterprises in improving cutting efficiency.

Strengthen cooperation with cutting tool manufacturers

With the help of cutting tool manufacturers, the application level and processing efficiency of tools in enterprises will be improved. At this stage, enterprises should rely more on the help of tool manufacturers to improve the application of cutting tools. Modern cutting tool manufacturers have mastered a lot of cutting technology resources and information, and have established the business purpose of improving cutting efficiency for users. They are a professional team of cutting technology socialization. Their strong scientific research force, huge development funds, modern technological equipment and advanced management concepts have promoted the progress of modern cutting technology. With the help of cutting tool manufacturers, we should help enterprises to improve the application level and processing efficiency of cutting tools and shorten the delivery cycle. This is the secret of gaining competitive advantages for foreign cutting tool users, and we should imitate it.

China's cutlery manufacturers should further accelerate the transformation of business philosophy, give full play to their advantages in cutting tool materials, coatings, tool design, and actively provide users with technical support and after-sales service of cutters, and become reliable partners of users.

At present, the pace of development of the domestic machinery manufacturing industry is speeding up. It is the severe period that challenges and opportunities coexist. Therefore, we need to renew our concepts and understand advanced cutting tools in order to optimize processing procedures, improve product accuracy, increase labor productivity, reduce costs, shorten delivery time and speed up the development of new products. In addition to increasing investment in CNC production equipment, we need to increase input and application of advanced cutters and realize the rapid development of enterprises.
