High Accuracy ER Sealed Collet install
1. Install the groove of the spring collet into the eccentric circle of the nut, push the spring collet in the direction indiCATEEed by the arrow until you hear a click, which means the spring collet has been installed in place.
2. Then install the spring collet onto the prop and make sure the tool is installed in place
3. Install the nut onto the handle and lock it with a wrench. (It is recommended to use a torque wrench to tighten the nut)


After screwing the nut off the toolholder, pull out the toolholder, push it inward from the front of the spring collet and press it downward against the bottom of the eccentric circle at the same time, and push the spring collet diagonally until the spring collet and nut are disassembled



ER Sealed Collet


ER sealing collet is a type of collet used in machining operations to securely hold a workpiece or tool in place. It is designed with a sealing feature that helps prevent coolant or other fluids from entering the collet and affecting the machining process.

The sealing mechanism of an ER sealing collet typically consists of rubber or elastomeric seals that are integrated into the collet design. These seals create a barrier between the collet and the outside environment, preventing the ingress of fluids.

ER sealing collets are commonly used in industries such as automotive, aerospace, and medical, where precision machining and coolant control are critical. They provide a reliable solution for maintaining a clean and controlled machining environment, reducing the risk of contamination and improving overall machining accuracy and efficiency.

In addition to the sealing feature, ER sealing collets also offer the benefits of high gripping force, quick tool change capability, and compatibility with a wide range of tool sizes. They are available in various sizes and configurations to suit different machining requirements.
