Powerful NT Tool Holder NT50 Multi Lock Milling Collet Chuck

NT Power Milling Chuck Multi-Lock Collet Chuck, Powerful Tool Holder

NT Power Milling Chuck Multi-Lock Collet Chuck,Powerful tool holder, suitable for rough machining and semi rough machining of molds and products, and other processes with large cutting volume. The groove design and internal 208 needle roller ratchet rotation design of the product can hold the milling cutter more effectively, so as to ensure that the milling cutter will not slide and vibrate during rough cutting.

ISO tool holder Product features:
1. The clamping part is thickened to improve rigidity and prevent vibration.
2. The unique R-angle crevice structure can make the clamping part deform evenly. With unique and strong clamping force and stable runout and precision, the clamping force is strong, and it will not loosen during cutting, with small vibration runout and high precision.
3. The clamping force is strong, which is suitable for heavy cutting, and also takes into account semi precision machining. The structural design and technology of the powerful knife handle are advanced. In the protective ring of the knife handle, more needle rollers than other similar products are placed. The needle rollers are made of special steel and will never deform. Because the needle rollers are closely arranged, the needle rollers will not hurt the transmission surface under heavy load.
4. Three layers of dust-proof design, each layer has an O-ring to ensure that no water, oil and powder enter, and the service life of the knife handle is increased by 5%.

Products advantages

1. higher system accuracy

System accuracy, including positioning system folder to precision and cutter positioning repeatability. The former refers to the connection precision tool and CNC knife handle, handle with spindle of machine tool; the latter refers to every time after changing a knife tool system accuracy of consistency. The tool system has higher precision and can guarantee the static and dynamic stability of the tool system under high speed machining.
2. higher system stiffness
The static and dynamic stiffness of the tool system is an important factor affecting the machining precision and cutting performance. The stiffness of the tool system will lead to the vibration of the cutting tool system, thereby reducing the machining accuracy, and increasing the tool wear, reducing the service life of the cutter.
3. better dynamic balance
Under the condition of high speed machining, the unbalance of the fine quality will cause huge centrifugal force. Therefore, the dynamic balancing of high-speed tool system is very importan
