• Do you know the application and product characteristics of high speed toolholder

  2020 / 09 / 17

  Facing the challenge of flexible and efficient production in modern manufacturing industry, the increasingly fierce market competition and the pressure of reducing manufacturing cost, high-speed machining has become the key point to enhance the competitiveness of manufacturing industry. High speed machining is different from traditional machining. In contrast, the high-speed machining spindle speed is high, the cutting feed speed is high, and the cutting amount is small, but the material removal amount per unit time is increased by 3-6 times. With high efficiency, high precision and high surface quality as its basic characteristics, it has been more and more widely used in automobile industry, aerospace, mold manufacturing, electronic industry and instrument industry, and is an important part of modern advanced manufacturing technology. High speed cutting technology can effectively shorten the production cycle and reduce the processing cost. However, in the actual processing, sometimes its processing effect does not reach the expected goal. Of course, there are many reasons, but one of the key factors is that the tool holder matching with the high-speed spindle is not correctly selected. If the high-speed operation of the machine tool spindle does not have the appropriate tool holder, not only can not achieve the expected performance, but also may damage the precision bearing of the machine tool spindle and reduce the service life of the machine tool. If you want to ensure satisfactory machining accuracy in high-speed machining, you have to choose the appropriate tool holder, which often fails to attract people's attention. However, as an important tool holder connecting the machine tool spindle and cutting tool, whether the manufactured parts meet the requirements of relevant standards or become defective products, whether the cutting tools used wil

• Matters needing attention in use of telescopic torque tapping tool holder

  1. Telescopic mechanism of tapping toolholder The tapping tool handle has its own telescopic mechanism. This is to prevent double screw and tap pitch and mechanical feed can be smooth synchronous. It must be used within the range of expansion and contraction. ① . excessive elongation When the elongation limit is exceeded, the black mark will come out. Please speed up the feed rate of the machine tool ② . over compression Machine tool feed faster than tap feed, compression mechanism action, please reduce the machine feed, not close. 2. When the bottom hole is small (when processing difficult cutting materials, the phenomenon of insufficient bottom hole hole is more), the torque protection mechanism makes the tap idle. In this case, do not adjust the torque (zk tapping sleeve), please enlarge the bottom hole. 3. During blind hole tapping, when the z-axis command of the program is too deep, when the spindle rotation stops, the hole bottom cannot be extended due to touching the bottom under the action of rotary force. When reverse, the original length which cannot be recovered at the exit is easy to touch the blind orifice. In this case, deepen the bottom hole or reduce the instruction value. 4. In the case of Z-type tapping toolholder, when the machine is fed in a fixed way, z-point reverses to start z-rise. The tapping toolholder is in the shortened state, and the z-axis rises, and the orifice is ea

  When selecting products 1. Check the size and shape of spindle hole and toolholder. 2. Select the cutting tool with suitable size and shape and matching with the tool holder. 3. Select suitable cutting conditions. When handling products 1. When transporting the product and taking it out of the box, pay attention to avoid product ejection or falling. 2. Special care must be taken when handling multiple packaged products or heavy tool handles at the same time. 3. Do not attempt to refit or disassemble the toolholder. 4. Pay attention to no scratch, scratch, debris or rust on the tool holder and tool holder. 5. Do not connect the part contacting the thread. When installing cutting tools 1. When installing cutting tools in the tool holder, please wear protective equipment. 2. When installing the cutting tool in the toolholder, make sure it is absolutely fixed. When installed on the machine tool 1. When installing the tool holder, make sure that there is no dust on the machine spindle hole, tool handle or tool holder. Scratches, or rust.
