How to choose a powerful chuck tool holder

The powerful chuck shank is a tool shank CNC Tool Holder commonly used in cutting processing. It is used for the clamping of straight shank tools such as milling cutters and reamers. The clamping spring has small clamping deformation. The clamping tool shank diameter tolerance is h6, and its clamping The force is greater and the tightening accuracy is better. You can replace different collets to clamp milling cutters and reamers with different shank diameters.

However, during the processing process, the diameter of the front end of the powerful shank is larger than that of the spring chuck. Easy to interfere. The powerful chuck shank is suitable for clamping milling cutters, the clamping force is more uniform in the clamping length, and can withstand larger radial forces. For end milling, high-quality side locking chucks or ER spring chucks may be the best choice. For powerful tool holders, it is suitable for traditional milling machines, used for heavy cutting and precision cutting.


Types of CNC shank taper shank: it depends on the way the shank is connected to the machine tool. The choice of the connection method between the tool holder and the machine tool spindle mainly considers whether the tool change method is automatic or manual, the size of the clamping force, the size of the taper, the source of the clamping force, and the rotation speed. There are two most commonly used, namely the steep taper shank hollow cone shank HSK. The steep taper shank is abbreviated type or type or general type.


The taper of this tool holder is relatively large and it is the most commonly used tool holder. It can withstand higher rotation speed and higher torque, and is mostly used for automatic tool change machine tools. The taper shank is directly installed in the taper hole of the main shaft of the machine tool, and there are connecting bolt pull studs on the top of the tool holder. At the same time, it is mainly clamped by the friction between the tool holder and the main shaft wall of the machine tool.
