COLLET CHUCKS

Collet chucks are used for clamping parts on a lathe during internal boring or facing operations. They are used where standard 3 or 4 jaw chucks would distort or mark the OD of the part being held.

Collets are made of high quality steels, hardened and ground to precision limits. A wide range of sizes can be produced and accuracies of 0.005mm T.I.R achieved at nominal size.

The slots are fully sealed to prevent ingress of swarf and coolant oil into the mechanism. Loading is simple, direct and repeatable. Positive release is incorporated to eliminate the need for self releasing tapers.

Collet Chucks are ideal for large, medium or small production runs, and can be used in conjunction with robot loading and drawbar actuation.

Actuation methods:

Drawbar actuated : This method allows automatic, in-cycle clamping of the part. This is particularly useful when combined with robotic loading and un-loading. Operation is by the drawbar through the spindle to a rotating cylinder and the back of the machine. This allows accurate control of the clamping force.

Thread actuated : This manually operated method is suitable where drawbar actuation is not available. The sleeve is energised using a threaded nut on the front of the collet. Mounting options:

Spindle nose mounted : This mounting method is simple, yet accurate and efficient. The chuck mounts onto the spindle of the machine replacing the standard machine chuck.

Face plate mounted : When direct spindle nose mounting is inappropriate, mounting to a faceplate or the face of the chuck is possible.
