Such cutting operations may occur either after or instead of forming processes such as forging, extruding, investment casting, or sand casting. CNC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools.

Worse place I have ever worked at. Favoritism and lack of pay rates is what this place is known for. They give no raises and management are always giving negative vibes. I would not recommend anyone to work here.$20- $35/ hr is a scam. Pay is for operator not set up individual
