Castings produced by investment casting do not require any further machining for finishing of the surface.

Castings produced by investment casting do not require any further machining for finishing of the surface. Correct Answer True

As control of grain size and its orientation is possible in investment castings, so it makes the casting ready for use without any requirement of machining. This is particularly useful for those hard to machine materials such as nimonic alloys. So this process saves time and money both, which is usually spent on machining for other processes.
