Linear Saw, Machining Method Using Same and Numerical Control Machining Device

Abstract

The present invention provides a linear saw, and a machining method and a numerical control machining device that use the linear saw. The linear saw includes a machining part, used for cutting a workpiece in a linear extension direction of the linear saw and forming a machined slot in the workpiece. The linear saw further includes a space-keeping part, which is disposed so that the entire linear saw does not contact the machined slot or is not subjected to an acting force from the machined slot when the space-keeping part passes through the machined slot. Because the linear saw has a space-keeping structure, the linear saw has time and space to recover from deformation produced after cutting a workpiece, thereby efficiently preventing an accumulated error and greatly improving position precision of a machined gap.
