What is CNC Turning?

A CNC turning machine in operationLet’s first work to give an understanding of turning. Turning is a machining process in which the workpiece (like a metal part) is rotated at a high speed, while a cutting tool is used to cut away the parts of the workpiece which aren’t needed. The cutting tool does not rotate, and it moves in a linear pattern. But, the cutting tool may move along a set of angles or curves.

Turning is normally done on the exterior surface of the workpiece, but sometimes it is also carried out on the inside. At that point, the process is known as boring. Similarly, cutting faces on the external side of the workpiece while it is rotating is known as facing.

Why is Turning Important?

What is a CNC Machine?

Machine tools to cut, shear, bore or grind metallic parts for use in the manufacturing sector have existed even before the Industrial Revolution. But early machine tools were driven by hand using levers and gears; later on, electric motors and hydraulic systems were used, and now computers are used to control them. Before understanding a CNC machine, it is better to have some know-how of what numerical control is.

What is a Machine Shop?

Inside Kosmo Machine Inc.'s machine shopThere is some confusion when the term ‘machine shop’ pops up; some people think it is where a machine is produced. However, that’s not true. A machine shop is simply a place, location, building, company or room where machining is carried out. Machining refers to the cutting of raw materials in order to convert them to the desired size and shape.

Machining is done on metallic parts as well as plastic, ceramic, wood, and various composites. A person who performs machining it is called a machinist. Different types of hand tools, cutting tools, power tools, and machine tools are used in a machine shop. It can be done as a hobby, business or both. A machine shop can be a separate shop or a part of a large factory where manufacturing takes place.

The end product of a machine shop is a part which can be made of metal, plastic, wood, ceramic, etc. The parts are then sold to other manufacturing industries such as the automotive industry, aircraft industry, power generation industry, or shipbuilding industry.
