ER Clamping Nuts Series ER20A Collet Nut er collet nut clamping nuts
ER Clamping Nuts Series ER20A Collet 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
ER collet nut clamping nuts are used in machine tool appliCATEEions to secure ER collets in place. ER collets are commonly used in milling, drilling, and turning operations to hold workpieces or cutting tools in place.
The clamping nuts are typically threaded and designed to fit onto the collet holder. They have slots or holes on their outer surface to allow for tightening or loosening using a wrench or spanner. The clamping nuts apply pressure to the collet, which in turn grips the workpiece or cutting tool.
ER collet nut clamping nuts are available in various sizes to accommodate different ER collet sizes. They are usually made from high-quality steel or other durable materials to ensure a secure and reliable grip.
When using ER collets and clamping nuts, it is important to follow the manufacturer's instructions to ensure proper installation and tightening. Over-tightening or under-tightening can lead to poor clamping and potential safety hazards.

ER20A collet nut is a component used in CNC milling machines and other machining appliCATEEions. It is designed to hold the collet securely in place, allowing for precise and accurate machining operations. The ER20A collet nut is typically made of high-quality steel and features a threaded design that allows it to be easily tightened and loosened. It is compatible with ER20A collets, which are available in various sizes to accommodate different tool diameters. The collet nut is an essential part of the toolholding system and plays a crucial role in maintaining tool stability and minimizing runout during machining operations.
