45 60 90 Degree BT Pull Stud,The cnc pull stud of the tool holder is tightened. When changing the tool, the tool holder should be loosened. The automatic clamping mechanism of the tool inside the spindle is the special mechanism of the CNC machine tool processing center. The drawing shows the structure of the spindle of the machining center. The cutter can be loaded and unloaded automatically on the spindle and clamped automatically. The working principle is as follows: when the cutter 2 is loaded into the spindle hole, the pull pin 3 at the back of the handle is sent to the front of the spindle pull rod. Under the action of the disc spring, the cutter is tightened by the elastic claw.


BT Pull stud 45 Degree pull studs : one end of the cnc pull stud is connected with the machine tool chuck, the other end is connected with the tool holder, the d part is clipped in according to the degree of the machine tool chuck, and the G part has threads and knife handle tightening. Through the axial force transmitted by the cnc pull rod, the pull rod joint and the cnc pull stud, the tool holder is tightened. When changing the tool, it is required to loosen the tool holder. When the cnc pull stud is installed on the spindle of the common machine tool or the numerical control machine tool, the arc joint of the rod body is connected with the front end of the pull rod structure. The screw joint of the cnc pull stud is connected with the inner screw hole of the tool holder extending into the spindle hole, thus realizing the use of the tool holder on the common machine tool and the numerical control machine tool. The tool holder can be used not only in machining centers, but also in common machine tools and CNC machine tools, which improves the universality of the tool holder and reduces the production cost.

BT50 pull stud is a type of tool holder used in CNC (Computer Numerical Control) machine tools. It is designed to securely hold the cutting tool in place during machining operations.

The BT50 pull stud is specifically designed to fit into a BT50 spindle taper, which is a popular type of spindle used in many CNC machine tools. The pull stud is inserted into the spindle taper, and a retention knob is used to secure it in place.

The pull stud has a threaded end that allows the cutting tool to be attached. The thread size and pitch are standardized to ensure compatibility with various types of cutting tools.

The BT50 pull stud is known for its high clamping force, which helps to prevent tool slippage during heavy machining operations. It is commonly used in appliCATEEions that require high cutting forces, such as milling, drilling, and tapping.

Overall, the BT50 pull stud is an essential component in CNC machine tools, as it ensures the stability and accuracy of the cutting tool during machining operations.
