Hardware CNC lathe processing and knife
Whether in the external force or have the internal force,
precision metal processing performance characteristics are not available in the traditional process technology.
In the CNC lathe processing programming point selection should consider the following points: so that programming is not simple. Resulting in the smallest processing error. Easy to check during processing. Knife point in the
CNC machine tool easy to find. Should be easy to calculate the coordinates of the knife point. Try to make the process of infeed or retreat the shortest route, and easy tool change. Try to fit the design reference or positioning datum of the part. Hardware CNC lathe processing
Material in the external force (load) under the action of resistance to deformation and fracture capacity. The unit area of the material is stressed by the load. Hardness: refers to the material resistance to other harder pressure on the surface of its ability, commonly used hardness according to its range of determination of the hardness (HBS, HBW) and Rockwell hardness (HKA, HKB, HRC). Elongation: The percentage of the total elongation and the length of the original gauge after the tensile fracture. Sectional shrinkage of the material in the tensile fracture, the maximum cross-section area and the original area percentage. Impact toughness: The ability of the material to withstand impact loads in Joules / cm 2 (J / cm2). Yield point: the yield strength, refers to the material in the stretch process, the material subjected to stress to a certain critical value, the load is no longer increase the deformation is to continue to increase or produce 0.2% L. Tensile strength: also called the strength limit refers to the material in the pull before the maximum stress value.
Precision metal processing to implement fully automated production methods, due to the unique performance, not only can reduce labor costs can control the production of bad products
