The parts with biggest size and smallest size are most difficult to be processed by CNC Machine. The parts with biggest tolerance scope is most difficult to be processed by CNC machine. The parts with complicated infrastructure is most difficult to be processed by CNC Machine.

If your equipment is advanced enough and your workers are experienced enough, you will not fail when you need to manufacture the big size part with complicated structure or small size part with high precision tolerance. Just like the company -- 2Fprototype, their CNC equipment can process the parts with largest size 3.0 Meter * 1.6 Meter * 1.6 Meter, the highest precision can reach 0.01mm.

So in the CNC machining field every boss always need to promote their device ability and labor ability to reinforce their market competition. But all of these need the investment. So if you have only limit cashes and workshop is small, you only can receive prototype project or small quantity orders from your customers. We have to say CNC Machining is also a Cash-Burning Sector.
