Hydraulic holders are high-precision tools widely used in the CNC machining and manufacturing industry. They utilize hydraulic oil pressure to achieve tool clamping. By employing a unique clamping method, hydraulic holders evenly tighten the tool onto the holder through the pressure of the hydraulic oil, thereby achieving high-precision cutting operations. Hydraulic holders have advantages such as quick tool installation, vibration reduction, maintenance-free, strong contamination resistance, ease of use, and safety.
The working principle of hydraulic holders involves the use of two concentric cylindrical sleeves to form a cylindrical cavity, filling one of the cylinders with hydraulic oil and applying a certain pressure to the oil. This pressure is uniformly transmitted to every part of the oil cavity, causing the outer cylinder wall (the thinner part) to expand outward, thereby achieving tight clamping of the inner bore and the outer diameter. Because the thin wall uniformly withstands the oil pressure, the clamping accuracy is very high.
The performance parameters of hydraulic holders mainly include tool runout and clamping torque. Among them, tool runout is one of the key indicators for measuring the clamping accuracy of the tool holder, and hydraulic holders can generally control this indicator within a very small range (e.g., 0.003mm). Clamping torque reflects the tool holder's capability to clamp the tool, and the range of clamping torque for hydraulic holders is broad, capable of meeting different machining needs.
