How to achieve six-jaw clamping with a three-jaw chuck

　　The most direct way to upgrade processing capabilities is to upgrade equipment, but it still requires cooperation between various parts of the processing. For example, it already has a 5-axis DMG machine tool, which has the ability to process parts with a diameter of 840mm, a length of 500mm, and a maximum weight of 600kg. It can produce a variety of parts including circular, rectangular, and irregular geometric shapes. The traditional three-jaw chuck cannot meet the demand, and a safe, fast and flexible clamping method needs to be found to ensure the efficient operation of the new machine.

　　Floating clamping solution

　　The clamping methods of the following group of products are worthy of reference. For easily deformed parts and diversified combination clamping workpieces, through the combination of claws and components, the floating centering clamping patent can solve the centering processing problems of rectangular and geometrically irregular parts.

　　▲Clamping square, round, and asymmetric parts

　　Processing of easily deformable thin-walled parts:

　　One of the solutions to the problem of clamping deformation of thin-walled parts is to increase the number of clamping points. What if there was a simple way to double the number of clamping points on a chuck without replacing the chuck? Is it possible? After being combined with the floating jaws, the traditional three-jaw chuck can easily achieve six-jaw clamping, and the clamping diameter can be quickly adjusted within a wide range of sizes, which not only reduces the deformation of the workpiece, but also saves the time of clamping the workpiece.

　　Six-claw and eight-claw clamping:

　　The floating jaw system is suitable for parts with non-perfect round appearance or parts that have been deformed after heat treatment. After use, the traditional three-claw chuck can realize the function of a six-claw chuck. The mechanical floating mechanism of the integral slide realizes reliable six-point floating clamping, effectively reducing the deformation of the workpiece. The clamping diameter range can also be adjusted within a wide range to adapt to the clamping of workpieces of different sizes. Using floating jaws on a four-jaw floating centering chuck can achieve eight-point clamping of thin-walled workpieces. At this time, the clamping deformation of the workpiece can be reduced to a few tenths of that during three-point clamping.

　　Deformation comparison:

　　Stress analysis of working conditions simulated by engineering software: When clamped with three claws, the internal roundness of the workpiece after deformation is 0.365mm: When clamped with six claws, the internal roundness of the workpiece after deformation is 0.020mm: When clamped with four claws, the internal roundness of the workpiece after deformation is 0.105mm: When clamped with eight claws, the internal roundness of the workpiece after deformation is 0.0 10mm: It can be seen from this that the more the number of clamping points, the more effective the deformation of thin-walled parts is controlled. This combination of floating chuck + claw is different from the single clamping performance of the three (four) claw chuck. Through the combination, different ways of clamping traditional square, round, special-shaped parts and easily deformable thin-walled parts are realized.
