Machining (particle separation processing)
Due to the possibility of wide application, machining is an unavoidable technology in almost all branches of industry. To remain competitive in the market, it is important to ensure productivity, quality, economy and reliability.
Machining as a system consists of three necessary elements: the workpiece, the tool and the machine tool.
The main advantages of machining are the following:
- achieving high manufacturing accuracy,
- narrow tolerances and surface quality,
- possibility of processing different materials,
- possibility of processing even the most complex shapes,
- processing of hardened materials,
- very little impact on the structure of the material,
- making individual pieces and large series.
The most common machining processes are turning and milling.
Turning is a process of processing by separating particles (cutting) of mostly rotational (symmetrical and asymmetrical, round and non-round) surfaces. It is performed on machine tools, lathes, where the main (cutting) movement is circular and is performed by the workpiece.
Milling is a particle separation process in which the main motion (rotational) is performed by a tool, and the auxiliary (shear) motion is performed by the workpiece.
Achieving quality and narrow tolerances is made possible by the use of modern lathes and machining centers from the Japanese manufacturer Okuma.
The use of machining centers enables the production of products of demanding geometry with a smaller number of clamps and shorter production time.
The most commonly used machining tool materials are hard metals and high speed steels. Due to the achievement of the quality of the workpieces, the increase of the cutting ability of the tools and the smaller influence on the wear processes, only the tools of proven manufacturers are used.
