Jingrui measuring machine tool casting process parameters introduced: Extensive use of the latest casting technology achievements, improve the level of casting technology to reduce casting defects, especially casting surface defects. The appearance quality of machine tool castings refers to the surface roughness of machine tool castings, surface defects, dimensional deviation, shape deviation, weight deviation. The choice of process parameters Process parameters on the casting dimensional accuracy and the outline of a greater impact. After several process tests, each process parameters are carefully selected. The inherent quality of machine tools castings mainly refers to the chemical composition, physical properties, mechanical properties, metallographic structure and the existence of holes, cracks, inclusions, segregation inside the machine tool castings; machine tool castings quality refers to the casting of machine tools under different conditions Under the durability of the work, including wear-resistant, corrosion-resistant, heat shock-resistant fatigue, shock absorption and other performance and machinability, weldability and other process performance. That is based on the casting structure, weight and size, casting alloy properties and production conditions, select the appropriate parting surface and shape, core method, reasonable set of casting tendons, chilled iron, riser and pouring system.
