![]() A smooth diamond coating with very high abrasion resistance is especially suitable for materials such as graphite, hard metal and ceramic green bodies. The HSC compression cutters are available with various diamond coatings to provide an optimum solution for the customer's particular working process. HSC compression milling cutters are designed in particular for machining epoxy resin or polyester-based plastics with carbon or glass fibers and make it possible to produce surfaces in finishing quality (ra < 2 µm). In addition, the milling cutters are equipped with chip breakers so that rapid chip removal is guaranteed and the process temperature remains low. This allows delamination problems to be mastered much better. The milling cutters are available in three lengths so that compression can take place in the middle of the workpiece to achieve optimum results. ![]() ![]() You will find the appropriate machine deburring solutions with our multifunctional tools.Īt these milling cutters, the spiralization changes from left to right, which results in the axial cutting forces converging in the middle at one point, i.e. These must be removed before further use to avoid injury or damage. When processing plastic parts, sharp edges often occur. If a coolant is not permitted or possible, heat can be removed from the machining process with compressed air or cooled compressed air. If coolant is permitted, the plastic can be cooled during machining to reduce heat generation. Whether coolant can be used often depends on the production specifications of the end user and the plastic used. The material is quickly cut and transported away, it takes the heat with it and there is no thermal damage. Therefore, when machining plastics, high feed rates must be observed in comparison to the (relatively low) speed. Milling or drilling generates temperatures that melt the plastic or heat it to such an extent that its structure is damaged. This prevents the still hot chips from compacting again and sticking to the tool. Polished flutes on the drill or milling cutter facilitate the fast and clean removal of the plastic chips. Machining very soft plastics in particular is only possible with extremely sharp tools. Tools for plastics processing should have a large cutting angle and be extremely sharp. In some cases, the workpieces are quite large, so that vacuum clamping is necessary. ![]() The plastic should be as stress-free as possible during clamping in order to obtain finished parts that are as stress-free as possible. ![]()
