The milling machine is the heart of precision mechanics, a very important tool used in cnc machining services to work into complex shapes metal parts or other materials of spherical shapes.
There are two main types of milling machines, both with a horizontal plane x-y. The first, the vertical, has the engine mounted on a z-axis, for which the movement on three axes allows the machine to make holes or reaming; in that horizontal, instead, the motor is placed on a lateral guide and makes it similar to a large circular saw. It is mainly used to realize slots, grooves and continuous pockets.
In these two types of milling machine are added the so-called “machining centers”, which have a fixed desk, and the motorized head that moves along 4 or more axes.
The CNC milling machines have an accuracy of up to the order of microns (0.001 mm), although they require special working conditions such as an air-conditioned environment, a solid base of support, temperature sensors on the axles, optical guides.
Normally, milling machines are very solid, because they have to absorb the vibrations generated by motorized head without losing precision, why, when performing work on very hard materials or at very high speeds using special lubricants to optimize the cooling of the tip and to reduce the efforts.
