The regionality of temperature, the regionality of food, and the regionality of clothing are not uncommon, but the knives are still regional. The regional characteristics of the tool industry including alloy milling cutters and alloy drills including non-standard tools are particularly obvious.

 

The tool industry has been developing in Wenling for more than 30 years. Since the reform and opening up, this pillar industry has not only achieved sustainable development, but has also been extended in all aspects. Compared with the simple products such as drill bits and taps, the current products produced by Wenling City's measuring and cutting tool enterprises almost cover cutting tools. All categories: tools for processing various external surfaces, including turning tools, milling cutters and files, etc.; hole processing tools, including drills, reamers, reamers, and internal and external surface broaches, etc.; gear processing tools, including hobs, Gear shaper, bevel gear processing tools, etc.; thread processing workload, including taps, automatic opening and closing thread cutting heads, thread turning tools and thread milling cutters; cutting tools, including toothed circular saw blades, cutting turning tools and saw blade milling Knives, etc.; in addition, there are combined knives.

 

The development of tool materials plays a decisive role in the advancement of cutting technology. This article introduces the properties and scope of application of diamond, polycrystalline cubic boron nitride, ceramics, cemented carbide, high-speed steel and other tool materials used in cutting. The mechanism of tool damage is the theoretical basis for the reasonable selection of tool materials. The reasonable performance matching of tool materials and workpiece materials is the key basis for the selection of cutting tool materials. The tool materials must be selected according to the mechanical, physical and chemical properties of the tool materials and workpiece materials. Good cutting effect. The selection of cutting tool materials for the piston during cutting is explained.

 

Economy is one of the important indicators of tool materials. Although high-quality tool materials have a high cost per tool, because of their long service life, the cost allocated to each part is not necessarily high. Therefore, the economic effect should be considered comprehensively when selecting end mill materials.

Although the regional characteristics of knives are relatively obvious, the development status is not slack, and each has its own characteristics.
