Nowadays, plastic is used in an extremely versatile way. Plastic is one of the most frequently used and most popular materials worldwide. In addition to companies such as K&B Kunststoffdreherei, plastic processing also takes place in areas of application such as model making, deep drawing or sign engraving, to name just a few. In addition to the milling and machining of plastics, we also use other common methods for processing plastics. Appropriate tools and many years of experience also allow us to work by drilling, cutting, turning, gluing, welding and the like. Certain types of plastic such as rubber are not suitable for contact with a CNC milling cutter, for example, and can therefore only be machined by a cutting process. Compared to alternative machining methods, the milling of plastic has basically neither advantages nor disadvantages with regard to the quality of the end product. Depending on the material composition and the intended use, we choose between plastic processing by milling, punching, turning, cutting and so on. In this article, however, we would like to concentrate on the milling of plastics.
