Precision machining of steel casting
Precision machining of steel casting is different from machining of steel profile. Precision casting has already achieve quite exact shape of what is desired, thus it saves lots of machining compared with machining from steel profile directly. Also because of this reason, we usually have to consider machining surface and proper machining allowance before casting. Our regular procure is to work out raw casting drawing along with machining drawing to specify machining area and machining allowance on the drawing.

CNC machining is the kind of precision machining by CNC machines such as advanced machining centers which have top end 5 axis machining center, 4 axis double platform machining center, or CNC turning lathes which can also be developed to CNC turning center having capability of changing more than 15 cutters within one holding shift; CNC milling machine and CNC drilling and tapping centers.

RMC investment casting foundry has equipped with 4 axis machining centers, 15 sets of CNC turning lathes and 3 sets of cnc milling machines, along with assistant common versatile turning, milling, tapping, drilling and grinding machines, we have the capability of machining nearly all kinds of steel castings.
