Metalworking is the backbone of modern manufacturing: from small precision components to packaging machine prototypes<\/strong>, right through to high volume parts for automotive and aerospace. As an engineer, I look at it not only through the prism of \"how to make something\", but above all \"why choose this method\": which material properties<\/strong> we obtain, how long it will take the process itself<\/strong>whether it will provide high quality<\/strong> and repeatability dimensions<\/strong>. Below you will find a practical guide to types of metalworking<\/strong> - from metal machining<\/strong>, by plastic processing<\/strong> i heat treatment of metals<\/strong>to finishing and special techniques.<\/p>\n\n\n\n

CNC machining: when shape, tolerances and speed of implementation matter<\/h2>\n\n\n\n

Metal machining<\/strong> via removal of material<\/strong> (subtractive) is the most versatile in production of parts<\/strong> o specific shapes<\/strong> i different shapes<\/strong>: from prototypes to small- and medium-volume series. CNC machines<\/strong> (from Computer Numerical Control<\/em>) use numerical control<\/strong>to automatically perform rolling<\/strong>, milling<\/strong>, drilling<\/strong> or finishing of holes<\/strong>. Their strength is precision machining<\/strong>, quick changeovers and the ability to manufacture from a wide range of materials (steel, aluminium<\/strong>, copper, plastics).<\/p>\n<\/div>\n\n\n\n

In practice, you will most often encounter CNC milling<\/strong> i CNC turning<\/strong>. Milling machines move the tool in three (or more) axes, and the rotation<\/strong> performs the cutter; this is ideal for planes, pockets, threads and complex 3D surfaces. On lathes\/turning centres, on the other hand material<\/strong> (rod, bushing) rotates and the tool remains static - hence the outstanding efficiency with axisymmetric workpieces: shafts, bushings, flanges. Today, hybrids are common: lathe-milling centres with driven tools, Y axis and counter-spindle.<\/p>\n\n\n\n

If you want to delve deeper into specific tolerances, machining strategies (HPC\/HSM), tool selection and tooling materials, it is worth looking at the service providers' practical guides. See also the description of CNC technology<\/strong> on CNC machining<\/a> - You will find a cross-section of the processes and capabilities of our machine park, making it easier to choose the right method under the desired shape<\/strong> and tolerances.<\/p>\n\n\n\n

Forming: forming without loss of material<\/h2>\n\n\n\n

Plastic processing<\/strong> consists of metal forming<\/strong> through permanent deformations<\/strong> - without chips. This is usually the best choice when you need better mechanical properties<\/strong> (continuous fibre, favourable grain arrangement) and high performance for the series. For basic types<\/strong> credit rolling<\/strong>, forging<\/strong>, metal stamping<\/strong> (stamping), metal bending<\/strong>, drawing and extrusion. Rolling is excellent for strapping and sheets<\/strong> o thin<\/strong>; forging<\/strong> (cold, hot, warm) builds up the strength of shafts, connecting rods or rims; embossing<\/strong> and punching is the fast track to hundreds of thousands of repeatable sheet metal parts; bending<\/strong> closes the process of forming sections and enclosures.<\/p>\n<\/div>\n<\/div>\n\n\n\n
