EROWA fixture

  Aluminum shells  are produced and cast under high temperature conditions. The production speed of aluminum shells is faster and the cooling strength is greater. As a result, some elements in the alloy cannot be transformed into required elements within a specified time. Because of the presence of needle-like structures in this material, its hardness is higher and its plasticity is poor. In addition, the tensile strength of this manufacturing process is very low, and not only will there be no yellow rust in the high temperature state, but also cracks will appear. The aluminum shell produced in this way will have the presence of granular burrs. If the burrs are not cleaned up, they will have a poor hand feeling. Such particles are often accompanied by tadpole-like tails, which will be observed under a microscope. Moreover, the color of this impurity is gray and contains a lot of iron. How to maintain the aluminum shell: 1. When there are burrs on the surface of the workpiece, the burrs

  The production of   erowa fixtures   is a comprehensive science. We need to clarify the design tasks, analyze the drawings of the parts, master the machining process regulations of the workpieces, understand the functions, shapes, structural characteristics, materials and technical requirements of the workpieces; the processed surfaces, requirements, Data on margins, positioning datums, clamping surfaces, etc. Practice has proved that only by constantly summing up experience, carefully collecting design information, mastering design criteria, rationally drawing out the structure plan of the fixture, correctly arranging the manufacturing process and assembly process, it is possible to produce a reasonable structure even on the basis of limited conditions. Reliable positioning, economical and practical fixture. In addition, the design and application of the fixture greatly facilitate the processing of circular or shaft parts, with simple structure and convenient operation, which can re
