Features of CNC Machining

CNC Machining is the most common technics for rapid prototyping and volume production, because of the below features:

cnc milling

CNC Milling

CNC milling, particularly 5 axis milling, can be used to create complex shapes from brasses, mild and stainless steels, aluminum, titanium, and rigid plastic.

The advantage of multi-axis milling machines makes the CNC milling process versatile,  and tight tolerances (0.02 mm), for creating many different types of part features of complex geometries. 

As well, Milling is best process to create pressure die casting and plastic injection molding tooling.

CNC Turning

RpProto employs advanced machines with live tooling and automatic bar feeders, allowing us to perform some tasks without the need for additional setups.

The turning process can produce complex external and internal geometrieswith very tight tolerances and excellent surface finishes.

CNC turning is a more efficient method for any round shaped component, such as shafts, worms, and spheres, and is suitable for rapid prototype low-volume production.
