The cutting blade is an important part of the cutting machine.The main is to cut the large coil according to the process requirements into different specifications of small ring.Improper cutting machine blade selection, do not choose according to the mechanical configuration, will not meet the requirements of cutting index products, cutting materials will produce burr and produce a large number of cutting powder chips.Not only will reduce the cutting precision and speed, the consumption of raw materials.It is easy to reduce the service life of cutting blade and increase the production cost.
1. There are mainly two ways of cutting circular knives: cutting up and down disc knives and squeezing circular knives.Circular cutting is the main way of cutting thick film, composite thick film, paper and other materials.Cutting material film thickness of more than 100um is recommended to use a circular knife cutting.
2. The upper and lower disk cutting blade methods are widely used, mainly including tangential cutting and non-tangent cutting.Tangential cutting is the material is cut from the tangential direction of the upper and lower disc cutter, this kind of cutting is more convenient to the knife, the upper disc cutter and the lower disc cutter can be according to the requirements of the cutting width, easy to adjust the position.Its disadvantage is that the material is easy to drift in the cutting place, so the accuracy is not high, now generally not.Non-tangential cutting is the material and the lower disc cutter has a certain Angle of package, the lower disc cutter falls, the material will be cut.This cutting method can make the material not easy to drift, high cutting precision.But it is not convenient to adjust the knife, the disc knife installation, must be removed from the whole shaft.The circular cutter is suitable for cutting thick composite film and paper.
3. the circular knife extrusion cutting in the industry is not common in the application of the field, it is mainly composed of material speed and material speed synchronization and a certain Angle, the bottom roll and easy to adjust pneumatic cutting tool.This cutting method can be divided into thin plastic film, but also can be divided into thick paper, non-woven cloth.It is a more convenient cutting way, but also a development direction of cutting machine.
4. in the selection of cutting machine blade must be suitable for the machine blade, some users are always one-sided and objective pursuit of imported blades, but ignore the blade should be matched with their own model.In no distinction between the application of the blade and their own use, it is considered that only imported blade is a good, durable blade.In fact, whether imported or domestic, only conducive to the application of products, is the right blade.
5. the advantages and disadvantages of the cutting machine blade is relative, the cutting effect of the blade is the key to the application.For example, the improper application of imported blades will not have a good result, while the domestic blades will have a good effect if the application is reasonable.
