Milling is a process, which is one of the types of cutting workpieces using a special tool, which is called a cutter. This cutting tool has multiple teeth, each of these teeth is a simple cutter. In the process of carrying out work on the processing of blanks, the cutter rotates and cuts its teeth into the blank advancing on it, at the same time, each of its teeth cuts off chips from the surface of the part. At the end of the process, the cutter removes the metal layer from the processed surface of the workpiece. Surface, which is obtained after the passage of the cutting tool, called processed, and the surface, formed on the workpiece directly by the cutting edge of the cutter, called the cutting surface. Milling can be cylindrical and end mill, but it depends on the axis of the cutting tool in relation to the machined surface.
Its useful to note, that milling is widely used in the engineering industry for processing various surfaces, including helical surfaces of parts and bodies of revolution. This is not surprising, because this method is considered quite accurate and one of the most efficient. A feature of this process is that, that it flows intermittently, unlike drilling, turning and other processing methods, in which the cutting edge contacts the workpiece until the end of the cutting process, and sale of CNC milling machines here.
Each of the teeth in the process of machining contacts the part for a certain period of time before the next infeed. Plunging is accompanied by impacts and all this leads to uneven processing. Such processing is accompanied by vibrations and other negative phenomena.. In the process of this type of processing, the cutter, which rotates on its axis, forms a body of revolution, whose cutting elements form a particular surface. The most widespread is the horizontal and vertical arrangement of the cutter axis on the machine..
The main types of milling include:
- milling axial cylindrical cylindrical, disc and end mills;
- face milling, disc and end mills;
- double-sided milling with disc, end and end mills;
- three-sided milling with end and keyway cutters;
- combined milling with sets of cutters;
- profile milling with shaped cylindrical and end mills.
