CNC BT tool shank Power Straight Milling Collet Chuck Set tool holder material 20CrMnTi


The powerful chuck tool holders is commonly used in the cutting process. It is used for the clamping of milling cutter, reamer and other straight shank tools. The clamping deformation of the clamping spring is small, and the diameter tolerance of the clamping tool handle is H6. The clamping force is relatively large, and the tightening accuracy is relatively good. Different collets can be replaced to clamp the milling cutter and reamer with different shank diameters. However, in the process of processing, the front diameter of the powerful chuck is smaller than that of the straight shank The handle of spring chuck is large and easy to interfere. The powerful chuck handle is suitable for clamping milling cutter. The clamping force is more uniform in the clamping length and can bear larger radial force. For end milling, high quality sidelock chuck or er spring chuck may be the best choice. For powerful toolholder, it is suitable for traditional milling machine for heavy cutting and precision cutting.


1. BT C Milling Collet Chuck The taper accuracy of tool shank 7:24 is less than AT3 and part of the standard sizes have been inspected in the last time by standard checking fixtures manufactured in Germany.

2. The inner hole of the tool handle is divided into six grooves to prevent the tool from turning and increase the clamping force.
3. Ball bearing cage made of special material prolongs service life and enhances clamping force.
4. BT C Milling Collet Chuck It has large clamping force and high centering accuracy, especially for strong cutting.
5. Dynamic balance: G6.3 8000/12 000 RPM can be made according to demand.
6. BT Powerful Tool Holder Material: 20CrMnTi.
7. BT C Milling Collet Chuck Hardness: HRC58-62.
8. Carburizing depth: > 0.8.
9. - 185C cryogenic treatment, 20 hours thermal aging.
10. BT C Milling Collet Chuck Electroless nickel plating for appearance finishing improves corrosion resistance, abrasion resistance and corrosion resistance, and achieves better anti-rust effect.

BT C milling collet chuck
1. BT C milling collet chuck Working Principle: The tool holder can be clamped by compressing the tool holder body by nuts.
2. Scope of appliCATEEion: heavy cutting of end milling cutter.
3. Features: High rigidity; strong clamping force, is the largest clamping force of all clamping handle. The anti-interference property is not good; the runout accuracy is generally below 0.02 mm, but it also achieves 5-10 um.
4. BT C milling collet chuck Points: Whether the elastic deformation is uniform or not, and whether the shrinkage is enough. (The chuck thickening design can increase rigidity and withstand heavy cutting of end milling cutter.)

BT C Milling Collet Chuck is made of high quality material. After heat treatment, it has better elasticity and wear resistance, high precision and stable performance. Mainly used for drilling, milling, reaming, tapping and grinding tool holder use.The structure design technology of powerful BT tool holder is advanced. In the protection ring of BT Tool holder, more needles are put into it than other similar products. The needle is made of special steel and will never be deformed. Because the needle is arranged tightly, the needle will not hurt the conveyor surface under heavy load. There are 15 types commonly used for BT C Milling Collet Chuck: 2 types of BT 30, 5 types of BT 40 and 8 types of BT 50. Refer to the size table of BT powerful tool holder for specific dimensions.
