When it comes to high-precision and stable tool holders, high-precision hydraulic tool holders are the first.

Hydraulic tool holder can be easily locked with only 1 T-wrench. With high precision, convenient operability, and diverse choices, hydraulic tool holders are used in more and more occasions. Taking our company's products as an example, here is a brief introduction to the hydraulic tool holder.

①Super slim type

This kind of tool holder is suitable for processing and mold processing of five-axis machining center, compound processing machine, etc. The outer diameter of the port is very small, which can well avoid interference with the workpiece. Taking into account high-speed machining, the high dynamic balance hydraulic structure adopted by BIG enables the maximum speed of the tool holder of BBT30 to reach a maximum of 35,000 rpm, and that of BBT40 and HSK-A63 can also reach a maximum of 30,000 rpm. Therefore, in the field of high-speed machining, hydraulic tool holders have also become a good choice.

② End face oil supply type

This tool holder can spray coolant from the front end of the tool holder on a machine tool with internal cooling.

Due to the hydraulic cavity and other mechanisms inside the hydraulic tool holder, it is very difficult to make an inner coolant hole in the limited space inside the tool holder. After unremitting research and development, BIG is the first company in the world to successfully manufacture an integrated hydraulic tool holder with end face oil supply. The front end of the handle has a water outlet, which can supply coolant or oil mist near the tip of the tool, thereby increasing the life of the cutting tool.

③Straight handle type

This type of tool holder can be used on hydraulic tool holders to achieve longer extension lengths, and can also be used on other tool holders to achieve the convenient operability of hydraulic tool holders. It not only improves the versatility of high-precision hydraulic tool holders, but also is the best choice for preventing interference.

④Hydraulic tool holder for fine machining
The HSK-E32 and HSK-E40 series dedicated to fine machining meet the requirements of using high-precision and stable repeatability hydraulic toolholders for high-speed rotation and fine machining. Tool shank diameters of Φ3mm and Φ4mm, which are commonly used in fine machining, can be used with confidence even with h6 tolerances. Taking HSK-E32 as an example, the inner diameter is Φ4mm, the extension length of the shank is controlled at 52mm, the weight is only 190g, the unbalance is less than 1g.mm, and the processing can be realized at a maximum speed of 45,000 rpm.
