CNC machining is far better than manual machining for a few specific reasons:
Accuracy: Programming a CNC to complete a job creates a consistent and accurate cut to ensure product quality. It can be repeated over and over in the exact same manner.
Cost Effectiveness: The cost of hiring a person to manually machine parts at scale is far more expensive than having a machine do it, as a machine will not tire, does not need lunch breaks, and can, theoretically run 24/7.
Speed: CNC lathing can churn out hundreds and hundreds of parts while retaining a consistent end product.
What is the Difference Between CNC Turning and Milling?
While CNC turning rotates the part for cutting, CNC milling rotates the tool to cut the part.
Going further, CNC turning will typically be used for cylindrical parts, as you rely on the part itself to rotate and create the friction to remove material when the cutting tool is placed against it.
On the other hand, CNC milling can create more complex parts as it is the cutting tool (rather than the material) that is spinning.
What is the Difference Between NC and CNC Machines?
NC’s are numerically controlled machines, whereas CNC’s are computer numerically controlled machines. Although they both are automatic machines that, in most cases, work on metal parts and are programmed to enable a desired operation, they differ in operation.
Numerical Control (NC) Machines are controlled with punch cards that are fed into the machine, making the programs difficult to modify. Even to make a small change to the program, the tape would have to be removed, modified, and fed back into the machines.
Computer Numerical Control (CNC) Machines have a built in computer to store the programs and modify the program via the control on the machine.
What is the CNC Turning Process?
The CNC lathing process involves material being secured to a spindle within a CNC machine, and a cutting tool moving in linear fashion to act upon the material and remove undesired material until he finished component is all that is left.
