What are the properties of high-speed toolholder??

March 30, 2022

Facing the challenge of flexible and efficient production in modern manufacturing industry, 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, high-speed cutting has high spindle speed, high cutting feed speed and small cutting volume, but the amount of material removal per unit time has increased by 3-6 times. High speed tool holder is characterized by high efficiency, high precision and high surface quality. It has been more and more widely used in automobile industry, aerospace, mold manufacturing, electronic industry, instrumentation and other industries. It is an important part of contemporary advanced manufacturing technology.

High speed machining technology can effectively shorten the production cycle and reduce the machining cost, but in the actual machining, sometimes its machining effect does not achieve the expected goal. Of course, there are many reasons, but the failure to correctly select the tool handle matched with the high-speed spindle is one of the key factors. If the high-speed operation of the machine tool spindle is not matched with a suitable tool handle, it will not only fail to achieve the expected performance, but also 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 cutting, you have to choose the corresponding tool handle, which often fails to attract people's attention. However, in fact, as a tool handle that plays an important role in connecting the machine tool spindle and cutting tools, whether the manufactured parts meet the requirements of relevant standards or become defective products, whether the cutting tools used will wear rapidly and whether they can be used for a long time It plays a decisive role in whether the cutting tools used can achieve the expected high efficiency and prolong the effective processing time of machine tools and tools.

The main factors affecting the above effect are the accuracy, dynamic balance, rigidity and clamping force of the tool handle. In high-speed machining, the tool handle should be selected correctly in a variety of high-speed cutting systems. When considering the tool handle standard, concentricity and radial runout should be given priority. The purpose of ensuring concentricity is to make the tool and spindle rotate correctly around the same axis, which is independent of the form of spindle.

For different spindle standards, bt-ger high-speed tool handle, bt-gsk high-speed tool handle, hsk-ger high-speed tool handle and hsk-gsk high-speed tool handle. These two different types of tool holder systems can well meet the requirements of high-speed machining, and have been applied to electronics, mold and auto parts industries, and achieved good machining results.
