ER16 ER20 ER25 ER32 ER40 ER Collet for CNC Tool Holder Lathe er collet
ER collet, also known as an emergency collet, is a type of collet used in machining operations. It is a precision tool holding device that is used to hold round workpieces securely in place during machining operations such as drilling, milling, and turning.
ER collets are commonly used in CNC machines and other high-precision machining equipment. They are designed to provide a high level of accuracy and repeatability, ensuring that workpieces are held securely and accurately during machining.
ER collets consist of a cylindrical body with a tapered inner surface. The collet is inserted into a collet chuck, which applies pressure to the collet, causing it to contract and grip the workpiece. The collet is typically tightened using a collet nut, which applies additional pressure to ensure a secure grip.
ER collets are available in various sizes, with different collet sizes corresponding to different workpiece diameters. They are known for their versatility, as they can hold a wide range of workpiece sizes within a given collet size range.
Overall, ER collets are a popular choice in the machining industry due to their precision, versatility, and ease of use. They provide a reliable and efficient method for securely holding workpieces during machining operations.

High precision ER collet with high elasticity and hardness meets your different needs, with an accuracy of 0.005mm, 0.008mm, and 0.015mm. Select a suitable machining accuracy that is compatible with BT30/BT40/BT50. Made of 65Mn spring steel, it has good elasticity and is more wear-resistant, maintaining high stability during high-speed operation. Widely used in milling, drilling, and tapping operations, suitable for various CNC, engraving machines, and other equipment.
ER collet:
1. The heat treatment method of martensite structure effectively avoids deformation and cracking
2. Clear and clear specifiCATEEions and markings Carbon black phosphating for corrosion protection and long-term non corrosion resistance
3. Grinding treatment process Surface grinding polishing treatment Abrasion resistant and heat resistant
4. The opening of the international opening standard chuck is fastened without slipping
5. Strong clamping force, good concentricity, high concentricity, no jitter during processing
6. All types of ER collet conform to the DIN 6499B Standard
