A novel biglide parallel grinder

A kinematics analysis and mechanism description of a novel biglide parallel grinder with six-controlled degree of freedom is presented in this paper. In comparison with hexapod machines, the mechanical structure and motion of this biglide parallel grinder is simple. Therefore, it's easy for this biglide parallel grinder to accomplish real-time control. Its workspace-to-volume ratio even is larger than conventional machine tools, and there is no singularity configuration as well. Because of using the parallel fixed length links, thermal deformation effects on accuracy of this grinder will be diminished. In addition to grinding, this grinder can be used for welding, painting, assembling, material handling and so on.
