[0002] A V-shaped opening is cut on a plate or profile so that two oblique edges are provided on the plate, thereby meeting the requirements of making the plate or profile into a finished product. For example, when making a long strip of profile into a photo frame, a V-opening needs to be cut on the profile but not cut, and then the profile is bent at the V-opening so that the two sides of the V-opening are butted together to form a corner of the photo frame, and the cut opening that is finally butted is set on a straight edge of the photo frame, so that the two ends of the cut opening are bonded or fixed in other ways to form a complete photo frame. However, in the prior art, due to insufficient cutting accuracy, the size of the straight edge of the cut opening after the cut opening is butted does not meet the requirements, resulting in low quality of the finished product.
