For example, for the finishing of the front wall baffle stamping die, the quality of the profile should be guaranteed. In general, large-area finishing requires that the milling or cutting edge is not changed during the milling process, and the milling of the entire profile is completed at one time, which requires a high degree of precision and durability for the milling cutter. Using the technical characteristics of high-speed cutting, the high-cutting speed, micro-feeding and multi-cut finishing process can be used to precisely meet the requirements of the free-form surface processing of the cover mold. In order to ensure easy feeding during the stamping process, the processing blade should be aligned with the feeding direction of the stamping material, so it is advisable to adopt a jet cutter. In order to ensure the surface processing quality, the cutting depth is set to 0.2mm, the cutting feed rate is 0.2mm/r, the cutting speed is 200m/min, the initial tool radius is 20mm ball end milling cutter, and the tool radius is 8mm ball head during clearing and milling. Milling cutter. Such a process that can only be finished by manual (advanced fitter) can now be completed by high-speed cutting, and the overall processing efficiency of the mold is significantly improved.
High speed cutting machine
Increasing the cutting line speed with the tool diameter determined will undoubtedly require a higher spindle speed; high feed rates and accelerations are also necessary in order to achieve an appropriate feed rate for each tooth of the tool by high speed. All of this requires the application of new machine tool manufacturing technologies, such as high-speed electric spindles, high-pitch large-pitch ball screws. At the same time, in order to remove the heat generating chips as quickly as possible and to better lubricate the front and rear flank, the application of the oil mist lubrication cooling device is also particularly important. Obviously, in order to meet the requirements of high-speed cutting technology, first of all, the machine itself has very high requirements: high-speed cutting machine tools must have high enough spindle speed, high dynamic performance, and high stiffness and vibration absorption performance.
For example, the HSMU series of 5-axis linkage high-speed machining machine developed by Swiss Mikron has adopted a new type of artificial marble bed material, and the integrally formed closed O-shaped structure has laid a good foundation for the vibration absorption and rigidity of the machine tool. The large pitch ball screw is driven by a water-cooled servo motor to ensure the stability of the machine at high feed rates. The standard on-board laser tool setting instrument ensures the measurement accuracy of the tool size at high speeds, thus ensuring machining accuracy. China's Zhejiang Wanxiang Group, Yantai Huofu Automobile Lock Co., Ltd. and Changchun FAW Fuao and other automobile manufacturing and auto parts manufacturing companies have introduced Mikron's high-speed machining center and high-speed 5-axis linkage machining center.
In the past ten years, the rapid development of the automobile industry in Shanghai and East China has provided a huge market demand for high-speed machining. The SAIC Group's Volkswagen, General Motors, Huizhong, Shangchai, Tone, and Sugawara are setting up high-speed cutting flexible production lines or high-speed milling, boring and drilling units for the machining of automotive interior and exterior cover molds and automotive engines. The commonly used cutting parameters are: spindle speed 8000 ~ 12000r / min, feed speed 40 ~ 80m / min, cutting depth 0.01 ~ 0.05mm: blank material is cast steel, forged, gray cast iron or aluminum alloy; There are mainly high speed tool steel, carbide, CBN, PCD, titanium coated tools or ceramic tools. Therefore, the machine tool and tool materials within the above parameters have a large market demand.

Tool belt is a piece of equipment used to hold and organize tools for easy access during work. Tool belts are commonly used by construction workers, carpenters, electricians, and other tradespeople who need quick access to their tools while working.
A typical tool belt consists of a belt made of leather or nylon with pockets or pouches attached to it. The pockets or pouches are designed to hold different types of tools, such as hammers, screwdrivers, pliers, and measuring tapes.
There are different types of tool belts available, including leather tool belts, nylon tool belts, and electrician tool belts. Some tool belts also have suspenders or shoulder straps to help distribute the weight of the tools more evenly and reduce strain on the back.
When choosing a tool belt, it is important to consider the type of work you will be doing and the types of tools you will need to carry. You should also consider the size and fit of the tool belt to ensure it is comfortable and does not interfere with your movements while working.
