Parallel kinematics machine
WebParallel kinematics machines, PKMs, are known to be characterized by many advantages like a lightweight construction and a high stiffness but also present some drawbacks, like the limited workspace, the great number of joints of the mechanical structure, and the complex kinematics, especially for 6-dof machines [ 1 ]. WebParallel Kinematics Machining (PKM) is considered the biggest breakthrough in machining technology since the invention of CNC machine tool. With PKM’s unique freedom of axis movements and 360 degree rotating cutting head, you can mill, drill tap, rough, and finish all sides (left, right, top, down, front, rear) of part in 1 setup. The dream ...
