Operation of 4SR20 High Clamping Force Collets

The 4SR20 high clamping force collets are precision tools designed for applications that require high clamping force to ensure a secure and stable grip on tools or workpieces. Their robustness and reliability make them ideal for high-precision and high-speed operations, where tool security and stability are paramount.

Construction Features

The collets are made with 4 slots and have an average concentricity error of 0.005mm. The shank of the tool to be clamped in the collet must be manufactured within h6 tolerance. They have a mechanical seal for coolant passage with a maximum pressure of 120 bar.

High Clamping Force Features

The 4SR20 collets are considered high clamping force for several reasons:

- High-Quality Materials: They are made of high-quality steel, offering excellent mechanical properties, including high resistance to deformation and wear. This material ensures that the collet maintains its clamping capacity even under heavy loads.

- Contact Surface Design: The contact surfaces of the collets are designed with specific geometry to maximize the contact area with the tool. This increases friction and clamping force, minimizing the risk of slippage.

- Clamping Mechanism: The internal mechanism of the 4SR20 collets is designed to effectively convert the closing force applied to the chuck into concentrated clamping force on the tool. This mechanism optimizes force distribution, ensuring uniform and powerful clamping.
