Installation of collet

July 27, 2021

Collet is a locking device for clamping tools or workpieces. It is usually used in drilling and milling machines and machining centers. After selecting the quality, pull the collet to identify the titanium Hao. The pull back collet is to pull the clamping part backward after the object is placed to clamp the collet. The forward push type moves the workpiece forward so that the collet clamps the object. At present, the collet material used in the industrial market is 65Mn. Collets are called elastic collets or collets. It is a cylindrical fixture used to confine the drill bit or milling cutter on the milling machine. It is also a fixing device for fixing and strengthening parts that need to be modified.

Installation procedure of collet collet

1. Check that the thread of the connecting nut can be locked into the connecting pipe.

2. Lock the connecting nut to the sleeve.

3. Reduce the oil pressure to the minimum state and actuate the oil cylinder to stop the piston at the front end. Turn the collet to lock the connecting nut into the thread of the connecting pipe. When locking, the taper hole of the collet must be concentric with the taper of the main shaft, and the positioning hole of the collet must be aligned with the positioning button at the nose end of the main shaft.

4. Operate the hydraulic cylinder to make the piston backward, combine the collet with the taper of the main shaft, and confirm that the positioning button has been assembled into the collet.

5. Lock the screw to fix the collet with the main shaft, gradually increase the oil pressure, and repeatedly actuate the collet to the maximum allowable thrust.

Installation procedure of collet

1. Remove the stop cover

2. Install the collet on the stop cover, and then install the collet into the sleeve.

3. Install the stop cover back into the body and lock the screws to check whether the clamping stroke of the collet is correct.

The clamping accuracy of the collet is between 0.001-0.008mm. With the use of tool handle and nut, different clamping accuracy is applied to different workpiece processing processes. The higher the accuracy requirements for the tool connection part, the higher the accuracy of collet shall be selected, which will directly affect the overall runout accuracy after clamping the tool. For high-precision processing, the high-Precision Collet shall be selected.
