CNC turning tools are used by CNC machines in the precision engineering industry to create precision engineered parts. CNC machining has overtaken manual input on the factory floor in the past decades, and it is now commonplace to see factory floors that are entirely deserted of human beings. To understand how computer numerical controlled technology works it is important to take a look at the different CNC turning tools that are used. Below, are some of the more commonly used CNC turning tools that you will find on a production line and on the factory floor.
CNC Machine Drills
CNC machine drills work in the same way that a hand held drill works; the difference between the two however is that in CNC a software platform is controlling the position of the cut as opposed to the human hand. The CAD software used in CNC can control the depth and position of the cut, and a CNC machine drill can repeatedly drill hundreds of parts to the exact same depth and parameters.
CNC Lathes
A CNC lathe is another of the most common CNC turning tools and CNC turning services used. A lathe is a machine that spins a part whilst a cutting blade removes excess materials. CNC lathes are used for sanding, drilling, deforming, cutting, and knurling. In order to make the process free from human intervention, cutting fluid will be used to remove the debris produced. A common example of a part that is made by a CNC lathe is a crankshaft.
Electrical Discharge Machining Machines
When minute and complex cuts or contours are required, electrical discharge machining can be used. EDMs are only used on ferrous alloys, and are only effective on electrical conductors. Rapid bursts of electricity from an electrode are used to melt or vaporize materials, the debris that is made being flushed away by the use of dielectric fluids.
CNC Milling Machines
CNC milling machines are used to make complex shapes from solids and metals. A CNC milling machine uses a work piece that is fixed to a moveable table, the material being guided around the rotating cutter. Inversely, the cutter can be made moveable across a stationary table, and some machines will include a spindle across the z axis. These types of CNC turning tools are commonly used in engraving.
CNC Plasma Cutting Machines
CNC plasma cutting machines use a plasma torch to cut material on a CNC table. Plasma cutting can handle thick pieces of material, and is often used in the cutting of ducts and vents.
Water Jet Cutting Machines
Water jet cutters in CNC provide a stream of highly pressurized water, acting as an erosive. This type of CNC machining is used when the material being cut would become heat damaged by other techniques.
Laser Cutting Machines
Lastly, when learning about the different CNC turning tools used in CNC and precision engineering, you should explore laser cutting machines. When a laser cutter is used it will melt or vaporize the excess material that is produced during the cutting process, allowing for a very high quality finish. CNC lasers provide the highest form of accuracy of all CNC tools.
