The planing motion of the planer is mainly relative to the periodic round-trip linear movement of the workpiece, and its applicable planing parts features are mostly plane, inclined and concave-convex surface processing, and can also be planed for various surfaces, but because of the limitations of its own processing characteristics, the speed of processing planing is not too high, and the planer returning to the stroke does not participate in the processing and cutting of parts, so it causes the loss of empty stroke, so the processing efficiency is relatively low.
At the same time, with the great technical improvement of numerical control and automation of other processing equipment, planing processing methods have been on the verge of gradually being replaced, from the perspective of many equipment upgrades, this type of processing machine tool has not received a great upgrade and innovation, to a large extent or stay in the original structure and layout, especially the vigorous development of vertical machining centers and gantry machining centers, as well as the continuous innovation of processing tools, but also in the processing range greatly replaced the processing advantages of planers, This relatively inefficient processing equipment is in a very awkward position.
