Hydraulic knife handle

There are significant differences between hydraulic tool holders and ordinary tool holders in multiple aspects, mainly reflected in their working principles, performance characteristics, applicable scenarios, and ease of operation.

1、 Working principle

Hydraulic knife handle: Based on the principle of hydraulic transmission, the blade is fixed by pressure transmitted through hydraulic oil. Specifically, the hydraulic tool holder is designed with an oil chamber inside. When hydraulic oil is filled and a certain pressure is applied, the wall of the oil chamber will deform, thereby achieving the expansion and clamping of the tool. This clamping method ensures the stability of the tool during high-speed rotation and high cutting forces.

Ordinary handle: The blade is usually fixed by a combination of mechanical structures such as a tool holder and a tool holder. The tool holder is responsible for clamping the blade, while the tool holder serves as the part that supports and transmits cutting force. This fixing method is relatively simple, but when facing high cutting forces and high-speed rotation, there may be looseness or unstable transmission of cutting forces.

2、 Performance characteristics

Hydraulic knife handle:

It has extremely high clamping rotation accuracy (≤ 0.003mm), which can effectively prevent tool breakage, improve cutting conditions, and reduce tool wear.

The oil in the oil chamber increases the structural damping, improves the dynamic characteristics of the tool holder clamping, and has excellent damping and vibration reduction performance, which can reduce the vibration during cutting and improve the surface quality of the workpiece.

Easy to operate, only simple tools such as hex wrenches are needed to load and unload cutting tools, without the need for complex auxiliary devices.

Suitable for efficient and high-speed cutting on large machine tools, capable of withstanding higher cutting forces and speeds.
