What should be paid attention to when choosing hydraulic tool chuck for deep hole machine tool? In view of this knowledge, we should know that the most important performance requirements for tool chucks are the clamping force, radial jump accuracy and balance mass that can reduce vibration when rotating at high speed. The accuracy of tool chuck runout must be less than 0.003mm. In order to support the high power of linear drive of machine tool, reducing the weight of the system composed of spindle, chuck and cutter is very beneficial to obtain good cutting results. The hydraulic tool holder not only can avoid maintenance and prevent dirt from entering, but also is easy to use, and can provide high clamping safety for the tool.
In order to obtain good machining results, the user's requirements for tool chucks have been clearly defined, and there are various kinds of chucks on the market to meet these requirements. Because different tool clamping systems have different technical characteristics and processing advantages, it is possible to find the most ideal tool chuck according to the specific processing purposes of users.
Hydraulic tool holder is a tool holding system suitable for most cutting applications. The hydraulic tool collet adopts a different tool clamping method from the conventional collet. The force is introduced by a screw mechanism (composed of thread, piston and seal). By manipulating (rotating) the screw mechanism, uniform hydraulic pressure can be generated inside the collet. This pressure is transmitted to an expansion steel sleeve for clamping the tool.
The hydraulic tool clamping system can achieve the best radial jump accuracy and repeatability less than 0.003mm. When the tool is clamped by the hydraulic chuck, the hydraulic oil in the handle can provide a high clamping force. Due to avoiding a small amount of protruding workpiece materials caused by tool vibration, users can obtain higher workpiece surface machining quality and longer working time of chuck.
