Machine tool castings quality in all respects

Quality of the machine tool castings including appearance quality, internal quality and service quality. The appearance quality of machine tool castings refers to the set of machine tool castings surface roughness, surface defect, dimensions, shape, weight deviation deviation; the inner quality of casting machine casting machine mainly refers to the chemical composition, physical properties, mechanical properties, microstructure and exist in machine tool casting internal hole, crack, segregation, inclusion etc.; the use of machine tool castings quality refers to the working endurance ability, machine tool castings under different conditions, including wear resistance, corrosion resistance, spalling resistance, fatigue, shock absorbing properties and machinability, weldability process performance. The quality of the casting machine has a great influence on the mechanical properties of the product. For example, wear resistance and dimensional stability of machine tool castings, directly affects the precision of the machine tool maintenance.
