In the face of the challenge of flexible and efficient production in modern manufacturing, in the face of increasingly fierce market competition and pressure to continuously reduce manufacturing costs, high-speed machining has become a key point to enhance the competitiveness of the manufacturing industry. High-speed machining is different from traditional machining methods. In contrast, the high-speed machining spindle speed is high, the cutting feed rate is high, and the cutting amount is small, but the material removal per unit time is increased by 3-6 times. It is characterized by high efficiency, high precision and high surface quality. It has been widely used in the automotive industry, aerospace, mold manufacturing, electronics industry, instrumentation and other industries, and is an important component of contemporary advanced manufacturing technology. part.

High-speed machining technology can effectively shorten the production cycle and reduce the processing cost, but in 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 the failure to correctly select the tool holder that matches the high-speed spindle. If the high-speed operation of the machine tool spindle is not matched with a suitable tool holder, it will not only fail to achieve the expected performance, but also may damage the precision bearings of the machine tool spindle and reduce the life of the machine tool. If you want to ensure satisfactory machining accuracy in high-speed cutting, you have to choose the corresponding tool holder, which often fails to attract people's attention, but in fact, as a tool holder that connects the machine tool spindle and the cutting tool, it plays an important role. Whether the manufactured parts meet the requirements of relevant standards or become waste products, whether the used cutting tools will wear quickly and whether they can be used for a long time, whether the used cutting tools can achieve the expected high efficiency, and whether they can be extended. The effective machining time of the machine tool and the tool plays a decisive role.

The main factors affecting the above effect are the accuracy, dynamic balance, rigidity and clamping force of the tool holder. Therefore, when determining the use of high-speed cutting, it should be able to correctly select the tool holder system suitable for high-speed cutting among a wide variety of tool holder systems. When considering the tool holder standard, the concentricity and radial runout should be given priority. The purpose of ensuring the concentricity is to make the tool and the spindle rotate correctly around the same axis, which has nothing to do with the form of the spindle. For different spindle standards, HIPPSC has launched the BT-GER high-speed tool holder, BT-GSK high-speed tool holder, HSK-GER high-speed tool holder and HSK-GSK high-speed tool holder with technical patents independently developed. These two different types of tool holder systems can well meet the requirements of high-speed cutting and have been used in electronics, mold and auto parts industries, and have achieved good processing results.
