CNC Turning is a process that is used for precision machining to produce cylindrical components like hubs, rods, pulleys, etc., through metal cutting while using Computer Numerically Controlled lathes. CNC Lathe, a machine tool, is well programmed through well-known machine control units or computer-aided machining software. A machinist programs the software controlled machine and set the needed cutting tools to produce the final product according to the given technical drawing specifications.
CNC Turning is the most simple and important process used for plastic machining. It is utilized where the precision tool generates materials after inserting the single cutter point into the material turning. The cutting procedure is executed through a cutting tool that is applied either at the right angle to the axis or parallel of the work piece. It is done through exercising pressure on the work piece or the weaker material to form the flexible shapes of the material. Sometimes through Computer Numerically Controlled lathe, the cut surface is formed by executing the helical feed as it results in rotation.
The cutting tool is used until the precise depth and dimension is achieved. CNC Turning can be done on both sides, inside or outside as far as the needs and specifications require. Parts that are too large to balance and cause difficulty in rotating around one center point, are worked on a machining center featuring a U axis. The turning length is about 1000mm between centers with a speed range of 4,000 revolutions per minute and 46kW drive power.
The CNC turning process cuts the plastic into various shapes like pointed, simple plain surface, tapered ends, contour, curve, fillet and radius profiles with threaded surface. These cut and turned pieces are used to create shafts, rods, bushes, pulleys and much more. This turning process applies well to the most rigid materials like Aluminum, Stainless Steel, Copper, Nylon, Polycarbonate, Acrylic, Brass, Teflon, Titanium, ABS, PVC, etc., that can be controlled with the software program tooling. The CNC turning is more economical than the CNC milling as it reduces the cost of production by minimizing the design elements. However, this also puts a limitation to the flexibility of designs.
CNC turning has various advantages as the turning tools are said to deliver components at a faster production rate with optimum manufacturing accuracy. In fact, the automation of the CNC turning process allows reaching tight dimensional tolerances in every piece. Some more advantages include the high level of parts uniformity or consistency, attainment of optimum cycle times for all components and quick execution of larger volume. Example of parts made by CNC turning include Robot Parts, Shift knobs, Motorcycle Parts, Auto Parts, Toy Parts, Knobs, etc., And parts made through this process are used everywhere in metal industries, plastic industries and even in aerospace industries.
