Hydraulic tool holder supplier

BT series hydraulic tool holderThe clamping method is different from the traditional tool holder system. Tightening only requires a pressure bolt. When the bolt is tightened, it will push the sealing block of the piston to generate a hydraulic oil pressure inside the tool holder. This pressure is evenly transmitted from the circumferential direction to the steel expansion sleeve, and the expansion wall then clamps the tool.

In addition, this type of tool holder not only has maintenance free function and anti fouling ability, but also is easy to use and securely clamps the tool. Because when tightening the tool, the clamping pressure can guide any oil or impurities on the tool holder into the small groove in the expansion sleeve (processing), which can clean the surface area for clamping and keep it dry, eliminate slipping, and ensure that the torque of the spindle can be well transmitted to the tool. By using this tool clamping system, the radial runout error accuracy and repeat positioning accuracy of the system can be controlled below 3 μ m. Due to the presence of high-pressure oil pressure inside the tool holder, when the tool is clamped, the internal oil chamber structure and the presence of high-pressure oil greatly increase the structural damping, effectively preventing vibration of the tool and machine spindle. Practical applications have shown that using this clamping system can not only improve machining accuracy and quality, but also double the service life of cutting tools in cutting processes.The clamping method is different from the traditional tool holder system.

What are the characteristics of hydraulic tool holders?(1) The hydraulic tool holder has a clamping rotation accuracy of * (≤ 0.003mm). In drilling and reaming processes, it can greatly improve the dimensional accuracy of the hole and effectively prevent tool breakage; In milling, the multi blade cutting tool can uniformly cut into the workpiece, thereby improving the cutting state and reducing tool wear. (2) The oil in the oil chamber of the hydraulic tool holder also increases the structural damping, thereby improving the dynamic characteristics of the tool holder clamping and making it have excellent damping and vibration reduction performance. It can reduce the vibration generated during cutting and improve the surface quality of the workpiece. (3) Hydraulic tool holders are very convenient for loading and unloading cutting tools, as long as a hexagonal wrench is used, the tools can be easily loaded and unloaded without any auxiliary devices.
