The problem of workpiece deformation in machining is a difficult problem to solve. First, we must analyze the causes of the deformation and then take measures to deal with it. Our common reasons are: shaft parts in turning are easy to produce ellipse or edge circle, taper, bending, especially the pr

H2. 1. Holding time.The length of holding time depends on the investment casting material and wall thickness. For castings with high melting point, high crystallization temperature range and thick wall, the holding time is longer. For the casting of small and thin wall of crystallization temperature
