There are many different options in machining services that can be used to create any type of part or component. Today, most OEMs and even those requiring a small volume production of parts typically choose CNC services, providing precision, tight tolerances, and components that meet the specific standards required by the customer.
However, knowing when to choose turning, milling, drilling, or broaching may be more of a challenge. In most cases, the specifics of the job as well as the type of metal, alloy, or other material to be used as the workpiece. This is essential for several reasons, including how effectively the equipment can cut or machine the workpiece. This, in turn, impacts the tolerances that can be produced through the use of the given CNC equipment.
The Movement Factor
As milling and turning are the two most common options for producing precision parts and components, it is important to understand the difference in CNC turning and CNC milling services.
With the use of CNC milling services, the cutting tool rotates around the workpiece, removing the specific depth and width of the metal to produce the desired shape. Depending on the number of axes on the equipment, this can create a range of different paths and provide a single equipment option for even complex parts.
With CNC turning, the workpiece itself turns while the cutting tool does not. This means that the shape of the workpiece must be cylindrical and symmetrical, which is not necessary for CNC milling services.
