With the continuous development of industrial technology, the requirements for high-precision machining and high-speed machining are getting higher and higher. In this context, shrink-fit tool holders emerged as the times required. As a representative of high-precision tool holders, its working principle and advantages have gradually been widely recognized and applied.
The shrink-fit tool holders offer unique advantages over traditional collet tool holders. The the shrink-fit tool holder adopts a one-piece design, which does not require additional pressure nut and collets to assist in clamping the tool. This simplified structure makes the tool holder high accuracy and more stable in dynamic balance.
So, how does the shrink-fit tool holder clamp and remove the tool?
Its core is to use the difference in thermal expansion coefficient between the tool holder (heat-shrinkable die steel/special heat-shrinkable stainless steel) and the tool (tungsten carbide) to forcefully clamp and remove the tool.
Clamping: By using a special heat shrinking machine for heating, the inner hole of the tool holder will expand thermally under the action of heat, so that the tool can be smoothly put into the inner hole of the tool holder. When clamping, a large friction force is generated to ensure the transmission of large torque.
Disassembly: Use a special heat shrinking machine for heating, and the tool holder will expand thermally under the action of heat, while the expansion degree of the tool is relatively small. So that the tool can be easily removed from the inner hole of the chuck.
Due to its unique working principle, high precision, high stability and high efficiency, the shrink-fit tool holder has become the first choice in many industrial fields. With the further development of machining technology, it is believed that heat-shrink tool holders will have a broader application prospect and bring more convenience and benefits to industrial production.
