The optimization of machines and devices, increased requirements concerning precision, measurement accuracy and shape of units’ elements – all of that causes a constant need for modernisation of the technologies applied in machining methods.

How does machining work?

Machining is a type of subtractive manufacturing. This process includes removing the excess of material from the product in order to get a desirable shape, dimensions and surface quality. The material removed from the product gets transformed into shavings. The machining process is conducted on machine tools with the use of cutting tools. The type of used machine tools as well as the type of used cutting tools have a major impact on the quality and the efficiency of the process. Different types of the machining are: turning, milling, whittling, gouging, drilling and grinding. Depending on the accuracy of the machining, the final product is made within 3 main stages – roughing, detailing and finishing.

The technologies of machining

In the recent years, the technology of machining has been developing dynamically. Specialists are looking for innovative solutions that enable increasing the efficiency and the improvement of the machining processes’ quality. Cutting machines are adjusted to palletisation and robotization of replacing cutting elements. Among the most often used technologies are;
– CNC milling – a type of machining used by means of special tools – milling cutters, which is a basic element of the numerically controlled machine tool
– CNC turning – in this process, the tool is moving in a rectilinear feed motion
– Grinding – one of the machining types (abrasive machining), in which the main tool is a snagging wheel or sandpaper. It includes abrading roughness of machining surfaces, what in turn causes the surface roughness to diminish.

The most modern technologies of machining

Conducting the above-mentioned processes of machining requires using tested and modernised machines, which should have optimised systems of control, as well as improved constructions. High technical level of the mechatronic machines positively influences the rationalization of the product as well as the diligence and the durability of produced elements. Modern machines combine a few type of machining, e.g. lathe-milling machine, which also has the possibility to automatically replace pallets (lathe) or automatic feeder of machined material (milling machine)
The machining technologies allow to receive complicated and untypical shapes of products, made from different types of materials such as metals, wood or glass. To change the original form of elements, specialists use methods that include milling and turning CNC, machining with high temperatures or dry machining. Distinguished technologies contribute to receive the high quality of products and a significant improvement of production processes.
