Keyless Drill Chuck

Product Description

The Keyless Drill Chuck  is a tool holding device specifically designed for high-precision machining, combining the functions of a drill chuck and a tool shank. It features a monolithic structure design, offering high rigidity, high coaxiality, and high precision, which ensures exceptional stability and repeatability during 

high-speed rotation and precision machining. The APU integrated drill chuck arbor is commonly used in CNC machines and machining centers, particularly suited for applications requiring high-precision drilling, milling, and tapping. Its compact design and superior performance make it widely used in industries such as aerospace, automotive manufacturing, and mold processing.

Product System

High Rigidity and Stability: The monolithic design reduces connections between components, enhancing overall rigidity and effectively minimizing vibrations during high-speed machining, ensuring process stability.

High Coaxiality: The integrated structure ensures extremely high coaxiality between the arbor and the chuck, guaranteeing precision during drilling or cutting, making it particularly suitable for high-precision machining requirements.

Product Advantages

High Repeatability: The integrated design eliminates assembly errors that may occur in traditional split structures, ensuring high repeatability each time the tool is changed.

Compact Design: The compact structure reduces the overall tool length, making it suitable for use in space-constrained machining environments while also improving the dynamic performance of the machine tool.

Product 3D diagram

The 3D diagram of the Keyless Drill Chuck  showcases its precise structural design and functional features. The 3D diagram clearly presents the monolithic structure of the arbor, including the chuck section, the shank connection, and the internal clamping mechanism. Through the 3D perspective, the compact design, high-precision clamping surface, and optimized force transmission path can be intuitively observed. The overall design reflects characteristics such as high rigidity, high coaxiality, and high repeatability, making it suitable for high-precision machining scenarios.

Accuracy

The precision testing of the Keyless Drill Chuck follows a rigorous "three-bar, three-test" standard to ensure its high-precision performance with tools of different diameters. Taking a 13mm chuck as an example, the testing process involves using three test bars of 13mm, 8mm, and 4mm to measure the precision of a workpiece with a diameter four times that of the test bar. The required precision must be within 0.05mm, ensuring that the chuck maintains extremely high coaxiality and stability when clamping tools of various diameters. This testing method not only verifies the chuck's precision at its maximum clamping range but also comprehensively evaluates its performance under different working conditions through multi-diameter testing, thereby meeting the demands of high-precision machining.
