AI Technical Summary
Technical Problem
Existing power turrets suffer from vibration issues when installing the tool head, leading to excessive deviations in machining accuracy and affecting product quality.
Method used
The installation method using heat-shrink tool holders utilizes the principle of thermal expansion and contraction. The tool head is installed into the heat-shrink tool holder while it is heated, and after cooling, it tightly holds the tool head, reducing vibration transmission. The heat-shrink tool holder automatically compensates for manufacturing and assembly errors, ensuring coaxiality and clamping force.
Benefits of technology
It significantly reduces the impact of vibration, improves machining accuracy and stability, extends tool life, and enhances surface quality and yield.
