ER20-A for Collet Nut Tool Holder ER Nuts for clamping ER Collet

 

ER nut is a type of nut used to clamp an ER collet in place. ER collets are commonly used in milling machines, lathes, and other machining tools to hold cutting tools or workpieces securely.

The ER nut is threaded onto the collet and tightened to securely hold the tool or workpiece. It typically has a hexagonal shape, allowing it to be easily tightened or loosened with a wrench or spanner.

ER nuts are available in various sizes to match the corresponding ER collet size. They are made from high-quality materials such as steel or stainless steel to ensure durability and stability during machining operations.

When using an ER nut, it is important to ensure that it is tightened properly to prevent any slippage or movement of the collet. This will help maintain accuracy and precision in the machining process.

Overall, an ER nut is an essential component in clamping an ER collet, providing a secure and reliable grip for cutting tools or workpieces during machining operations.

 

ER Nut

ER20A Hex Nut ER clamping Nut ,The self-locking function of the barrel clamp ensures that the barrel clamp will not fall off during installation. Specially designed for high-speed machinery, good balance. The special anti-corrosion treatment reduces the friction between the clamp and the nut, greatly improves the clamping force, and has the ability to block pollutants.
1. ER Nut Materials: 42Crmo; 20CrMnTi
2.ER Collet Nut Hardness: HRC50-53
3. ER20A Nut for CNC Tool Holder Accuracy: A class (8 micron), AA class (5 micron)
4.ER Clamping Nut Model: A, M, UM/RD, KM/RD
5. Cryogenic treatment and thermal aging treatment are used in the process to improve the accuracy and dimensional stability.
6. Thread and 30 degree inclined surface are processed once. The tolerance grade of thread is 4H, and the accuracy is gradually tested.
7. Preset dynamic balance G2.50000/25000/30000 RPM;
8. Surface coating treatment, improve surface hardness, wear resistance, improve cleanliness, better rust and corrosion resistance, more stable accuracy, smoother surface, more comfortable feel, more beautiful appearance
