CNC Turned Component and its Process

CNC is a process that is used for precision machining in order to produce such cylindrical hubs, rods, pulleys, etc., by the cutting of metal, while using computer numerically controlled lathe. CNC lathe, a machine tool is programmed by known machine controls or computer-assisted machining. A machinist programs, the software-controlled machine and set the required cutting tools to produce the final product according to the given technical drawing specifications.

CNC turning is the simplest and most important process for plastic processing used. It is used where the precision tooling materials produced by inserting the individual mills turning point in the material. The cutting operation is performed by a cutting tool which is applied either parallel or perpendicular to the axis of the work piece. It is to exert on the work piece or the weaker material, to form said flexible molds of the material, carried out by pressure. Sometimes by computer numerically controlled lathe, the sectional area by performing the helical feed, as is formed in rotation.

The cutting tool is used, to the precise depth and dimension is attained. CNC turning can be carried out on both sides, internal or external call to the needs and requirements. Parts are too large to balance and cause difficulties in the rotation about a center point, are combined to a machining center with a U-axis. The rotation length is approx 1000mm between centers with a speed range of 4,000 rpm and 46kW power capacity.

The CNC turning process cuts the plastic into different shapes like pointed, simple smooth surface, tapered ends and contour, curve, fillet and radius profiles with surface provided.

This cut-and turned parts are used to create shafts, rods, bushings, pulleys and much more. This also applies to the turning process rigid materials such as aluminum, stainless steel, copper, nylon, polycarbonate, acrylic, brass, Teflon, titanium, ABS, PVC, etc., the tools can be controlled by the software program. 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 restricts the flexibility of the design.

CNC turning has several advantages, such as turning tools said components to provide production at a faster rate with optimum manufacturing accuracy. In fact, the automation of CNC turning process allows reaching tight dimensional tolerances in each piece. Some other advantages are the high uniformity or consistency parts, achieving the optimum cycle times for all components and rapid execution of larger volume. Example of parts are made by CNC turning robot parts, gear knobs, motorcycle parts, auto parts, toys, buttons, etc., and parts produced by this method anywhere in the metal industry, plastic industry and even in the air and space industry.
