Precision machining is a type of technical manufacturing that is essential in creating and designing machines, parts, tools, and other hardware that are essential in modern manufacturing to maintain process controls and tolerances that function under extremely tight specifications.
Precision machining removes excess, raw material from a work-piece, while holding close tolerance finishes, to create a finished product. Simply put, it means shaping large pieces of material into more precise parts, so that they can meet very exact specifications.
The term CNC stands for 'computer numerical control', and the CNC machining definition is that it is a subtractive manufacturing process which typically employs computerized controls and machine tools to remove layers of material from a stock piece—known as the blank or workpiece—and produces a custom-designed part.
Material:
Stainless steel/aluminum/brass/copper/titanium/steel
Advantages:
Operational efficiency. Fast production.Low Error.Less Material Waste.
The precision machining process depends largely on computer-controlled machines that can operate automatically and with great speed without any human intervention.
Disadvantages:
- Cost
CNC machining may have higher costs than other technologies—such as 3D printing—for single-part or very low-volume production runs. Although, CNC machining is cost-effective for higher quantities. There’s more waste simply due to the subtractive method, whereas 3D printing only uses the material that’s needed.
- Skill
CNC machining requires engineers who understand the software operation. A machine shop’s drills, lathes, cutters, mills, and other types of equipment are controlled by software and need machinists who understand how both software and equipment work.
