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, metal milling machines are indispensable. With their help, it is possible to produce rough, finishing and semi-finishing processing of surfaces of parts, both simple and shaped. Moreover, the workpieces can be steel and cast iron, from non-ferrous metals and plastics. On many other milling machines, you can drill, countersink and bore holes. And the use of a rotary table or dividing head makes it possible to produce 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 mass production. And the rigidity of such units is high enough to ensure high precision processing. A large range of spindle revolutions and feeds makes it possible to use various milling and drilling tools. And according to the location of the spindle, metal milling machines 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. A rotary milling machines make it possible to make processing continuous.
So, for example, in the post-Soviet space, the universal metal milling machine model 6P12 was popular. However, it can be found in many factories now. 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 you to use a tool that is equipped with plates of hard and synthetic superhard alloys, as well as mills made of high speed steel. This metal milling machine , the price of which corresponds to its quality, also has a rotary spindle head. With its help (through the manual axial feed mechanism), it is possible to process holes that are located at an angle reaching 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 guide rail lubrication and automated assembly lubrication. Especially these functions are suitable for large-scale production. Such machines have a mechanism designed to proportionally slow down the feeds. And the fastening of the tool in the spindle of the machine is mechanical. In addition, the movement along the coordinates is controlled by electromagnetic couplings. Another similar device brakes the spindle when it is stopped, and the mechanical drive clutch protects the feed drive from overloads. Also, such a machine meets safety precautions. And in this regard, it has a protective device that protects the milling machine from flying chips.
