Details with a complex profile are used in various modern devices. And they are made by various methods - casting, stamping, welding and, of course, cutting. And in this case, milling machines for metal are indispensable. They can be used for roughing, finishing and semi-finishing of the surfaces of parts, both simple and shaped. Moreover, blanks can be steel and cast iron, non-ferrous metals and plastics. On many milling machines, you can drill, countersink and bore holes. And the use of a rotary table or dividing head makes it possible to manufacture gears, sprockets, pinion shafts and other gear parts.
Therefore, metal milling machines can now be found both in a large enterprise and in a small workshop. They are suitable for single and serial production. And the rigidity of such units is high enough to ensure high processing accuracy. A wide range of spindle speeds and feeds makes it possible to use various milling and drilling tools. And bythe location of the spindle milling machines for metal can be vertical and horizontal. Also, in industries where there is a need to produce large batches of identical parts with high quality processing, copy-milling models are used. And carousel milling machines make it possible to make processing continuous.
So, for example, in the post-Soviet space, a universal milling machine for metal model 6P12 was popular. However, it can be found in many factories today. But today, machine tool builders produce its more advanced analogue - 6T12, which better meets modern requirements and has more functions. The power of its drives allows the use of tools that are equipped with inserts made of hard and synthetic superhard alloys, as well as milling cutters made of high speed steel. This milling machine for metal, the price of which corresponds to its quality, has a swivel spindle head. With its help (by means of a manual axial feed mechanism) it is possible to machine holes that are located at an angle of up to 45 degrees to the plane of the table.
Metal milling machines of this type have high performance, durability and reliability. They are characterized by high quality and precision processing. These units have individual lubrication of the guides and automated lubrication of the units. These functions are especially suitable for high-volume production. These machines have a mechanismdesigned to proportionally slow down feeds. And the fastening of the tool in the machine spindle is mechanical. In addition, movement along the coordinates is controlled by electromagnetic clutches. Another similar device slows down the spindle when it stops, and the feed drive is protected from overload by a mechanical safety clutch. Also, such a machine complies with safety regulations. And in this regard, it has a protective device that protects the miller from flying chips.
