Material
 In actual use, the paper cutter to cut the face of the object is varied, in addition to paper, cardboard, there are leather, plastic, cork flooring and PS version and so on. Due to the cutting of a wide range of materials, so it should for different materials, corresponding to different pressure feeder pressure, cutting edge angle of the mouth should also change, which guarantees high quality cutting products.
 Cutting edge angle of the mouth
 Cutting edge angle of the mouth of choice, is cutting the work is very important part. In other words, a good cutter, it is necessary with a good cutting blades and grinding processes. However, we found that during the cutter service, cutter users often are overlooked a lot of this, the results, often because the cutting blade sharpening means, methods, wrong angle, causing the impact to increase crop , the insurance screws loose, and even break, eventually leading to mechanical damage. Need to use the paper cutter cutting an increasingly wide range of materials, like aluminum foil hat standard beer, carbonless paper, honeycomb, magnetic cards, photographic film, these materials in the cutting process will encounter various practical problems. Such as NCR in the cutting prone to indentation, and magnetic cards, photographic film, pressure will appear in the paper cutting device fixed live, leading to cutting out waste and so on. These problems can be pressure by adjusting the pressure feeder, improved cutting blade and transmission can be resolved smoothly. However, these technical, as far as I know, currently only some paper cutter manufacturers can all be resolved.
