Er Collet For Collet Chuck

ER collet is the most widely used clamping system in the world used for a variety of machining applications including boring, milling, reaming, tapping and grinding.

The advantages of ER Type Collets are:
High polished finish for extra accuracy and long life, especially when clamped in ER chucks
Superior clamping strength
Fits all brands of ER holders

The benefits of ER Type Collets are:
Quality: Product consistency and worldwide acceptance
Material: Durability and increased collet life
Wide Clamping Range: Less collet inventory necessary
Broad Product Range: Versatility for a variety of applications
Clamping Length: Higher clamping power and improved T. I. R.
Matched Tooling System for Best Fit: Compatibility of the whole system results in maximum precision, balance and tool life
Precision: Increased tool life and part quality.

Collet chuck
Operation to Be Performed:
A collet chuck applies clamping force all around the circumference of the part instead of just at select contact areas. The result is tight concentricity. This can be particularly significant for second-operation work where accuracy relative to the first operation is a concern. Even when a jaw chuck is used for the first operation, a collet chuck may be used for the second operation because of its precision clamping. A jaw chuck with bored soft jaws repeats within 0.0006 to 0.0012 inch TIR. A collet chuck typically provides repeatability of 0.0005 inch TIR or better. The collet chuck can also be adjusted for concentricity during installation to further improve secondary operation.

Work piece Dimensions:
Collet chucks are best suited to work pieces smaller than 2 inches in diameter.
A collet chuck may also impose a limitation on the work piece length. Specifically, a collet chuck limits the machine's range of axial (Z-axis) travel, because its length is longer than that of a jaw chuck. When the machining length of a work piece is so long that just about all of the available travel of the machine is needed to cut it, then this requirement will probably dictate the use of a jaw chuck.


Lot Size:
Very large and very small lot sizes both help make the case for a collet chuck.
Where there are small lot sizes and lots of them, the collet chuck's advantage relates to change over time. Swapping jaws takes around 15 to 20 minutes for a standard jaw chuck or 1 minute on a jaw chuck specially designed for quick change, but the collet in a quick-change collet chuck can be changed in 15 to 20 seconds. The time savings add up where changeovers are frequent.
Similar time savings related to clamping add up where lot sizes are large. A collet chuck takes less time to open and close than a jaw chuck, shaving cycle time by reducing the non-cutting time from one piece to the next.
