Information
The main problems existing in the use of the HSK tool system at present are:
(1) The use conditions of the clamping system and clamping force are not scientifically formulated
Relevant institutions have conducted investigation and statistics on the actual tightening force of machining centers (machine tools) in production, and found that due to improper selection of the clamping system or improper use of the clamping system (such as the relaxation of the clamping spring), most of the machine tools The actual clamping force used is only about 70% of the specified clamping force, and the lowest is only 30%. This is very dangerous for high-speed machining or even normal machining.
(2) The existing manufacturing standards are unreasonable. The processing requirements of the HSK tool system are harsh and the products are expensive. Due to the demanding requirements of 2hi, the product
It is difficult to fully meet the current set standards. A Swiss company has tested the HSK tool holders produced by 15 well-known foreign companies, and only one company's products fully meet the DIN standard. At present, a large number of HSK tool systems that do not fully meet the specified manufacturing standards are still in normal use, which shows that the existing HSK
There is an unreasonable side to the manufacturing standards of tool systems.
(3) The conventional strength check cannot guarantee the reliability of the HSK taper surface fit. The HSK tool system and the spindle are clamped by the taper surface and the end surface at the same time. When the rotation speed is zero, due to the interference of the taper surface, the taper surface will The surface will be deformed, and once it is in a high-speed rotation state, this stress deformation will be more serious, thereby reducing the reliability of the tool system. The conventional strength check cannot guarantee the reliability requirements of the tool holder under discrete conditions of various parameters.
