CNC stands for computer numerical control and the process of shaping of metal and wood on lathe with the help of computer is called CNC Turning. The complete process of CNC turning is very interesting to discover.
Lathe is most important tool in machine shop which spins or rotates the block of material to achieve fine rotational symmetries. The process of spinning of material for required turning can also be done manually by hand but the chances of disturbance of precision and accuracy will be increased. Rotational cutter is located in center of CNC machine that removes and eliminates the unnecessary material according to instructions given by the computer.
Materials can be cut into several different shape including taper ends, plain surface contour and many more and with the help of these cuts, metal can be converted into various useful objects like shafts, hubs, rods bushes and pulleys. It can also be used for fabricating parts and circular cross sections materials. Rigid and hard materials can be processed very properly and are controlled by exclusive software program. It is very advantageous method as it reduces the cost of productions.
A cutting tool is traversed along two axis of motion, longitudinal and transverse. With the help of cutting tool and computer instructions, required depth of cutting can be achieved very smoothly without any trouble. Just two types of cutting can be done, inside or outside according to the requirements of manufacturer. The turning length is approximately 1000mm between centers and has a drive power and speed range up to 46kW and 4,000 revolution/minute respectively.
With the help of CNC milling, 2D, 3D and some compound structure materials can be formed. For short procedure CNC milling is more economical. Different parts of engine and machines are shaped and produces with the help of this process.
CNC turning machines provides most accurate results along with the fast production rate. The most beautiful feature of CNC machines is automation which prevent manufactures from repetition of same work. Part of machines are more consistent and uniform in their work and done their jobs very precisely. Achievement of optimum cycle times for all components and faster execution of larger volume are also remarkable characteristics of this process.
