Small Collets, Large Function -- ER Collets and Aerospace

In highly precision and demanding aerospace manufacturing, ER collets plays an irreplaceable role with its excellent clamping force, wide clamping range and excellent accuracy.

Today's aerospace processing industry is facing several tool-holder challenges: Machining materials is difficult, metal removal rates are not up to demand, and cumbersome components require long, unwieldy prop overhangs. In these cases, the tool holder must perform perfectly and provide strong gripping force, high precision and vibration control.

Aerospace factories have gone through many tests and found that the key to failure is the tool pulling out, vibration or pulsation. We can imagine that an aerospace factory will convert a week of machining time into an aircraft wing SPAR, and when the machining is finished, the milling cutter exits the tool holder, and the aircraft wing SPAR has only changed by such an insignificant amount as 0.060".

When expensive materials such as titanium alloy are processed, the impact of tool pulling is even greater. In order to prevent the impact of tool pulling out, aviation factories often use a specific locking system, using a special ER collets.

In this way, this additional solid part will have a convex joint or pin that can be embedded in the groove of the cutting tool because the tool will be turned to the back of the fixture. The position of the end of the locking system groove is very reliable.

With its excellent performance and wide applicability, ER collets plays a vital role in aerospace manufacturing. With the continuous progress of technology and the in-depth expansion of applications, ER collets will play a more important role in the aerospace field.
