HSK series
Structural principle of HSK tool holder
The HSK tool holder adopts double-sided positioning on the tapered surface (radial) and the flange end surface (axial), and the machine tool realizes a rigid connection with the spindle.
When the tool holder is installed on the spindle of the machine tool, the hollow short taper shank is in full contact with the taper hole of the spindle to play a centering role. At this time, there is a gap of about 0.1mm between the HSK tool holder flange and the spindle end surface.
Under the action of the tensioning mechanism, the backward movement of the pull rod causes the tapered surface of the front end to expand the elastic clamping jaw radially, and at the same time, the outer cone of the clamping jaw acts on the 30° cone surface of the inner hole of the hollow short tapered shank. Above, the hollow short taper shank produces elastic deformation, so that the end face of the tool is close to the end face of the spindle, and the function of positioning and clamping the tool holder, the taper face of the spindle and the end face of the spindle at the same time is realized.
Introduction to Knife Handle
High-speed cutting processing has become an important part of machining manufacturing technology. The processing performance of the traditional BT tool system has been difficult to meet the requirements of high-speed cutting.
The tool system can perform cutting at high speed, and it should meet the following basic conditions:
1. Higher system accuracy
System accuracy includes system positioning and clamping accuracy and tool repeat positioning accuracy. The former refers to the connection accuracy between the tool and the tool holder, and the tool holder and the machine spindle; the latter refers to the consistency of the tool system accuracy after each tool change. The tool system has high system accuracy to ensure the static and dynamic stability of the tool system under high-speed machining conditions.
2. Higher system stiffness
The static and dynamic stiffness of the tool system is an important factor that affects the machining accuracy and cutting performance. Insufficient rigidity of the tool system will cause the tool system to vibrate, thereby reducing the machining accuracy, and aggravating the wear of the tool, reducing the service life of the tool.
3. Better dynamic balance
Under the conditions of high-speed cutting, the unbalance of the tiny mass will cause huge centrifugal force, which will cause the machine tool to vibrate sharply during the machining process. Therefore, the dynamic balance of the high-speed tool system is very important.
