ISO Tool Holders Accessories ISO7388 Retention Knob Pull Stud,One end of the CNC pull stud is connected with the bayonet of the machine tool, one end is connected with the tool holder and the dpart is inserted in accordance with the degree of the machine bayonet. The g part is screwed and the handle is tightened. The axial force transmitted through the pull rod and the pull rod joint and the pull stud To achieve the tension of the handle. When the tool is changed, it is required to release the tool holder. When the pull stud is installed on the spindle of the ordinary machine tool or numerical control machine tool, the circular arc joint of the rod body is connected with the front end of the pull rod structure, and the screw joint of the pull stud is extended into the spindle shaft hole. Retention Stud,Nt Retention Knob Pull Stud ,Pull Stud For Nt, The screw holes in the shank of the shank are cooperatively connected to realize the use of the shank on an ordinary machine tool and a numerical control machine tool, so that the shank can be applied to a machining center as well as an ordinary machine tool and a numerical control machine tool, and the shank is improved. The versatility reduces production costs.

The puller of the holder is tightened. When the tool is changed, it is required to release the holder. The automatic clamping mechanism of the main tool inside the spindle is a unique mechanism of the CNC machining center. The picture shows the spindle structure of the machining center. The tool can be automatically loaded and unloaded on the spindle and automatically clamped. The working principle is as follows: When the tool 2 is installed in the spindle hole, the pull screw 3 at the rear of the tool holder is sent to the spindle. The front end of the spindle rod is tensioned by elastic claws under the action of a disc spring.
