This machine is applicable for bending bevel and suitable for double-way simultaneous process and single side process. The bending double-way beveling machine enjoys the advantages such as compact design configuration, beautiful outline, easy operation, high efficient processing, fine quality, with its products reaching the required criteria for bevel. This machine is in possession of machine processing cutter with novel structure, workpiece clamp with accurate positioning and locking apparatus with reliable performance. The cutting feed adopts hydraulic stepless timing loop with steady and superior performance and it can adjust cutting feed speed at random according to different calibers and wall thickness as well as rapid feed with empty space entering, slow cutting, rapid return, etc.. Its cutter holder can assemble three cutters at the same time, rational division of work and simultaneous cutting, which effectively improves production efficiency and product quality.
