What is Shrink Fit Chuck Tool Holder?

Creater heat-shrink tool holder utilizes the technical principle of thermal expansion and contraction, heating the tool using the induction technology of a heat shrink machine. Also known as sintered tools or thermal expansion tools, heat-shrink tool holders can achieve full-scale, ultra-high precision machining. The 360° complete circumferential clamping precision and rigidity are significantly enhanced.

The Principle of Shrink Fit  Tool Holders

The principle of heat-shrink tool holders is to use the difference in the thermal expansion coefficients of the tools to tightly clamp the tool's thermal installation system. This system uses a heat shrink machine for heating and clamping, making tool installation and removal simple and convenient. The tool installation part does not require the nuts and components needed for collet chucks. The simple and efficient, slender shape of the tool head allows for more practical tool extension length settings, highlighting the advantage of heat-shrink tool holders in deep cavity machining. During high-speed machining, the clamping is stable, and the high concentricity maintains higher machining precision.

Compared to tools made with other materials, the high thermal expansion coefficient allows for low-temperature thermal clamping and thermal removal. Regardless of the number of thermal clamping and removal operations performed, the material does not change, and the tool precision does not deteriorate. 

The high rigidity tool is short protruding, and the tool does not require the nuts and collets typically used for clamping, making it a lightweight and slender, one-piece type that avoids interference with the workpiece as much as possible. It can perform high rigidity, powerful, and stable cutting without chatter, achieving a high-quality machined surface. The high precision during runout effectively extends the tool life. It can accurately and precisely install tools without needing to adjust the clamping degree, thereby consistently achieving high precision installation and clamping, extending tool life thanks to durable machining. Multiple machining verifications show that the same tool can undergo thousands of thermal clamping and removal operations without precision changes, ensuring stable and reliable performance.

Advantages of Creater Shrink Fit Tool Holders

Quick Tool Installation and Removal

With the use of a heat shrink machine for heating, high power can complete tool installation and clamping within seconds. It only takes a few dozen seconds for cooling. The unique water cooling device can prevent deterioration of tool precision.

High Precision and Low Runout

The heat-shrink tool holder installation part does not have the nuts and collets required for collet chucks, making it simple and effective. The cold shrink clamping is powerful and stable, with tool runout ≤3μ, reducing heat-shrink tool holder wear and ensuring high precision during high-speed machining.

Slender Tool Head with Wide Application

The ultra-thin tip part and the diversity in tool shapes can be widely used in high-speed and high-precision machining, as well as deep hole machining.

Simple, Efficient, and Long-lasting

The thermal clamping and removal operations maintain precision even after thousands of uses of the same heat-shrink tool holder, ensuring stable and reliable performance, and a long usable life.
