ER collet clamping nut is a component used in collet chuck holders
to secure the collet in place. It is typically made of high-quality
steel and has a threaded design that allows it to be tightened onto
the collet chuck holder.
The ER collet clamping nut is responsible for applying the
necessary force to hold the collet firmly in place, ensuring
accurate and secure clamping of the workpiece. It is designed to
withstand the high forces and vibrations generated during machining
operations.
ER collet clamping nuts are available in various sizes to
accommodate different collet chuck holders and collet sizes. They
are often used in CNC machining appliCATEEions, where precision and
stability are crucial.
When selecting an ER collet clamping nut, it is important to
consider factors such as the size and type of collet chuck holder,
the intended appliCATEEion, and the compatibility with the collet
being used.
CNC ER Nuts Clamp Nut for tool holder ,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 for tool holder Materials: 42Crmo; 20CrMnTi
2.Er Collet Nut for tool holder Hardness: HRC50-53
3. Er Clamping Nut for tool holder Accuracy: A class (8 micron), AA
class (5 micron)
4.High Precision Clamping Nut for tool holder : 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
