When using, first put the chuck into the pressure cap, gently turn the circlip, until the eccentric part of the pressure cap is recessed into the circlip groove, push the circlip evenly in the direction of the arrow, and the cone can be broken. The ER chuck only needs to move the sliding sleeve to quickly replace the drilling and tapping sleeves. When drilling, the Morse sleeve automatically locks; when tapping, the torque overload can slide smoothly to avoid tap breakage. In addition, when changing the tool, use a wrench to loosen the pressure cap and take out the chuck and tool, remove the tool, push the circlip in the direction of the arrow to make it withdraw, and then replace it with a circlip of another hole diameter as needed.
When operating the ER chuck, the wrench reaches into the window and pulls the pull-push screw to easily clamp and loosen the tool. Since the outer diameter of the chuck adopts Morse taper, the repeatability error is small, and the clamp uses pull-push screws to make the head Reduced size for easier viewing and cooling.
The quality of the ER chuck itself includes the material, process flow, post-surface treatment, and final cleaning and packaging. If there is dirt and debris in the inner holes and gaps of the chuck, chipping will also affect the accuracy of the chuck. These factors are inevitable in production, and manufacturers need to strictly control all aspects of production. A little carelessness will affect the accuracy of the chuck.
