Power Chuck & Clamping Forces

In the field of mechanical engineering, the power chuck is a special type of power clamping device, which is used to clamp work pieces with radial symmetry, especially cylindrical objects.

About Power Chuck

In the field of mechanical engineering, the power chuck is a special type of power clamping device, which is used to clamp work pieces with radial symmetry, especially cylindrical objects.


Application in the drilling and milling tasks

Power chucks can also be used to hold rotating tools, such as rotating drills and milling cutters. In drilling applications, an additional chuck may be installed on the non-rotating tailstock case.

Jaw may be arranged on power chucks in a symmetrical pattern. The jaws are tightened to hold the tool or work piece. Generally, the jaws can be tightened or loosened with a power chuck key, which is a wrench-like tool designed for this purpose. Some jaw power chucks are keyless, and their tightening and loosening can only be done manually. The keyless design provides a faster and easier clamping and loosening mechanism, but this design has a lower clamping force.


Application in the turning tasks

In lathe machinery, the power chuck is usually installed on the rotating spindle in the headstock. Work piece spinning machines and tool spinning machines have some similar functions and outstanding processing characteristics. For example, in a lathe, the power chuck and cylinder system work together to execute the clamping mechanism, and the assembly of the two determines the output precision of the machine.

Compared with other machine tools, turning machines (lathes) is one of the oldest machine tools with thousands of years of history. Lathes can be divided into two main types according to the way of clamping the work piece.

The two types are vertical lathe and horizontal lathe. In a vertical lathe, the work piece is clamped vertically, and the cutting tool is installed in the same direction, so that the machining is performed vertically. Compared with horizontal lathes, the vertical clamping mechanism is more stable. Therefore, vertical lathes are often developed for high precision machining, such as automotive parts, aerospace parts, sports facilities, or some large work piece processing tasks.


Power chuck clamping in the vertical arrangement

In the vertical clamping mechanism, the lathe spindle is located behind the chuck. The spindle may be driven by belt or other drive mechanism. Like milling machines and machining centers, lathes can also be equipped with powered tools and tool magazines to improve their functionality and versatility and provide users with a wider range of machining possibilities.

Power turret is a modern standard accessory for CNC lathes, and one of the most important accessories for CNC lathe users. Taiwanese manufacturers have developed many high performance power turrets and power tools to support the needs of lathe users worldwide. Many power turrets are driven by a single servo motor, which can ensure the best processing effect and save the best energy consumption. At the same time, they can also provide great rigidity to the work piece, thereby providing ideal cutting performance. In addition to power turrets, tool magazines and automatic tool changers (ATC) are also the best selling products of Taiwan machine tool accessories suppliers.

Taiwan's tool magazine and ATC system can provide customers with the best tool change time according to their cycle time engineering to help customers meet their order needs. Compared with global competitors, Taiwanese manufacturers know better how to provide the best solutions and provide comprehensive services based on local conditions. Equipping these accessories actually makes the machine more modern and meets the ever-changing manufacturing requirements. Spindle, chuck and hydraulic cylinder manufacturing are also very developed in Taiwan. Along with the CNC lathes, there are a series of lathe accessories widely used in industrial fields around the world.
