Machining In Casting - An Overview
Casting can be used to create an exact form, in simpler terms casting is molten metal poured into a mold to create desired shape and pattern. Machining institutes a broad term, used to define how certain parts are cut away or altered into patterns and shapes that cannot be achieved through casting. Foundries in India have found tremendous benefit through machine casting, as machining as a process is predetermined in the design stage as a way to assimilate small tolerances that cannot be permitted through casting. Machining permits there to be more of an exact shape, size, pattern and detail.
Ductile Iron, also called spheroidal graphite cast iron or nodular cast iron is a form of cast iron known for its impact, elongation and fatigue resistance. Ductile Iron foundries in India, use machine casting on ductile iron as it yields better results in comparison to steel predominantly due to Greater depth to diameter drilling ratios, faster feed rates, higher spindle speeds and extended tool life. Casting provides the lowest cost of production supported by cast to a near end shape, though it might not provide the accuracy of machining.
Machinability is not an intrinsic property of the metal rather occurs as a result of the complex interactions and overlays of the workpiece and various devices used on it under different conditions. The heightened use of disposable inserts has reduced the costs and placed more emphasis on quality, bringing into consideration the use of grey iron. Grey iron has impressive compressive strength supported by wear resistance and good fatigue resistance this ultimately aids in working well under machine applications. Cast iron foundries in India have increasingly opted for both ductile and grey iron due to their specific properties that support machining in casting.
Iron foundries in India have found immense benefit in machine casting, as it has resulted in high speed production, allows for dimensional accuracy and permits multiple finishing techniques.
