There are many different operations that fall under the general term of machining. Each of these operations or processes uses different types of machines, and most now offer the option for both traditional, manual operations as well as CNC processes for extremely high tolerance requirements.
While drilling, boring and milling are some of the most commonly used operations, a turning operation is an ideal option for many types of parts and components. New systems incorporate CNC (computer numerical control) and automation to produce quality parts using a fast, effective process.
Turning is not a new technology, and it is based on one of the oldest known types of machines, the lathe. In fact, turning is done on a lathe, but it offers a greater variety of shapes and contours than can be created with a basic lathe.
The Basics of Turning
Like a lathe, a turning operation incorporates a turning workpiece and a single-point tool for cutting. This cutting tool moves in a parallel line to the rotation, create the specific shape of the exterior of the workpiece. The final result is a symmetrically shaped workpiece that is precise and created to the exacting standards required.
Turning can create a variety of shapes and contours. One of the most common uses of this process is to create a taper. This can be a consistent, smooth and seamless cylindrical shape or more a step-down type of tape.
In addition, a turning operation can include the process of creating specific grooves in the workpiece, and they can be different in depth and width on the same part. Facing is another common task completed through turning, and it allows a flat surface to be created. Facing can be used both before and after drilling and boring to provide a smooth surface.
