CNC milling, and the entire process is the treatment with the use of rotating knives, in order to remove material from the workpiece. Milling can be done at particular angle or perpendicularly to the tool axis. It covers a wide range of different operations from small individual to a large, heavy milling operations. It is one of the most commonly used processes in treatment of parts with various sizes and shapes. Milling can be carried out using a wide range of machine tools. Nowadays, when digitization and computerization are very popular, milling evolved into large machining centers (milling machines with automatic tool changer, magazines or rotary tools, CNC, cooling systems), usually classified as vertical machining centers (VMCs) and horizontal machining centers (HMC).
The milling cutter is a rotary tool, it can be used for various materials and with different directions. In contrast to the drilling, the cutter usually moves in the perpendicular direction to the axis in such a way that the cutting takes place on the periphery of the milling cutter. Milling process removes material by cutting many small elements, so called chips. This is accomplished by a milling cutter or a cylinder head with many teeth by moving the cutter at high speed, or progressive material. Feed and rotation speed of the cutter may be different depending on the combination of variables. The speed with which the material moves during milling is measured in units – the amount of material to be removed for a complete rotation of the cutter.
CNC machining centers in our company allow for the accomplishment of details, both in frontal milling process, in which the cutting is done mainly on the forehead of the cutter, and is used while processing flat surfaces in the workpiece or the implementation of a flat-bottomed nooks and during the process of peripheral milling wherein cut occurs mainly along the circumference of the cutter, so that the cross section of the milled surface is shaped into knife, wherein the milling is well suited for cutting deep slots, gear teeth.
In the process of CNC milling we use the tools called milling cutters. These tools may have cutting surfaces along their whole surface, so that they can be placed in the element (subterraneanly). Mills may also have cutting surfaces at theirs periphery to allow a circumferential milling. Tools optimized for a frontal milling, typically have only small knives at their ends, corners (so called head). Milling surfaces are usually made of a hard and heat resistant material, whereby a slow usage occurs. Cheaper tools are made of high speed steel (HSS). More expensive but slower are made of fritted carbide (VHM). In addition, in order to reduce friction and increase the life and hardness of the tools the coating is used.
After completion of the milling process, the elements can be treated in other metal working processes, including: threading, welding, sandblasting, painting, and other processing techniques, in order to achieve the desired effects.CNC milling is one of the most important services that we offer to our customers.
