In CNC turning and precision machining, workpieces with deep recesses, flanges, or irregular profiles can present significant clamping challenges. Conventional clamping methods may be limited by insufficient jaw stroke or potential interference, affecting machining stability and operational efficiency.
The CHANDOX EL / ELT Crank Type Long Jaw Stroke Hollow Power Chuck is specifically designed for workpieces with complex geometries. Its extended jaw stroke and greater clamping flexibility provide more freedom in machine setup and workpiece positioning.

The EL / ELT Series features a crank-type mechanism with a through-hole design and extra-long jaw stroke, allowing the jaws to effectively clear flanges and deep-recessed areas and reach suitable clamping positions with greater ease.
For specially contoured workpieces that are difficult to secure with conventional chucks, the EL / ELT Series offers a more versatile clamping solution for a wide range of workpieces and specialized machining applications.

2- & 3-Jaw Configurations for Greater Application Flexibility
The series is available in two configurations: the 3-jaw EL and the 2-jaw ELT, allowing users to select the appropriate model according to workpiece geometry, clamping requirements, and machining conditions.
The 3-jaw configuration is ideal for round or symmetrical workpieces, while the 2-jaw configuration is suited for certain irregularly shaped workpieces or applications requiring opposing clamping. This flexibility helps manufacturers accommodate diverse workpiece requirements while maintaining a stable and efficient clamping process.

Hydraulic Actuation for Stable, Reliable Operation
As power chucks, the EL / ELT Series is designed to operate with a hydraulic rotary cylinder and center draw tube, enabling stable and reliable clamping and unclamping.
Hydraulic actuation provides consistent and efficient clamping performance, making the EL / ELT Series well suited for CNC lathes, automated machining systems, and high-volume production environments requiring reliable, repeatable clamping.

Designed for Complex Workpieces
From deep-recessed and flanged workpieces to irregularly shaped components, the CHANDOX EL / ELT Series delivers the extended stroke, greater flexibility, and reliable clamping support required for complex machining applications—helping enhance machining stability and process efficiency.
