To produce high precision mechanical components, mechanic also performs metal turning. Metal turning is a mechanical process obtained through the removal of shavings. A rotary motion of the piece defines this processing. The cutting edge of the tool penetrates the material of the article, removing the excess part (stock), thus forming the chip metal turning.
In the case of turning, by definition, the “cutting motion” is possessed by the piece, which, being anchored with the lathe spindle is made to rotate. The tool, which in metal turning has the so-called “feed motion,” generally moves with rectilinear motions, parallel or inclined to the spindle axis, and, therefore, to the axis of the piece. Metal turning is a process to shape metal to convert in structures.
Design of Metal Turning
In fact, with the turning of metals, generally cylindrical, conical, spherical, and flat surfaces are obtained, but all revolutions are given precisely by the rotary motion of the work piece.
Thanks to these processes, it is possible to create various details via proper metal turning, usable in multiple industrial sectors, such as the pharmaceutical, automotive, naval, and packaging sectors, to name the most common is also covert metal turning process is running.
Metal turning owes its name, in fact, to the machine with which these processes are carried out, namely the lathe. To simplify, the tool with which the artisan’s potters make ceramic vases, cups, and bowls is also called a cutter: because even in their work, the “machine” rotates the piece to be worked.
Training of Molding
In precision mechanics, the course of metal turning, is an important phase and a dynamic one that has undergone various improvisations, compared to a simple rotary table. The motion of the part and the tool, today, can be controlled micro metrically, obtaining shapes, surfaces, geometries, and above all degrees of finish and precision, until a few years ago only imaginable.
Not only that: now on modern CNC lathes, it is also possible to mount motorized units, which are nothing more than small cutters, which therefore allow you to make radial holes metal turning, keyways, hexagonal shapes, radial square grooves, etc.
As with all the modern machine tools, there are two macro-groups into which lathes are divided: manual and CNC. As it is easy to guess, manual lathes are controlled, in every movement and rotation, by the operator via the process of metal turning. Therefore, much of the piece’s success, its quality, and above all, the timing of production is closely linked to the operator’s ability and experience.
For CNC lathes, on the other hand, both the rotation of the piece, the rotation of the tools and the movements of the tools, are controlled by a computerized control which, through the so-called brushless motors (without brushes), and recalculating worm screws of spheres metal turning, can control the position and roto translating movements with micrometric precision (0.001 mm).
All this is dictated by a program that decodes in machine language and it needs training to decipher the same. It is understood that the experience and the production capacity of the cutter have become somewhat different from the machine operator, moving on to create the programs to be entered into the lathe.
As for metal milling, few expert companies are operating in market who use only the latest generation CNC lathes for turning, and that ensures maximum precision work on any metal. The experience and specialization of high-skilled operators in metal turning, combined with the expert programmers’ extraordinary ability, can create correctly modeled parts without imperfections, which guarantee impeccable assembly in all mechanical components.
