Large area milling machines are devices designed for heavy production works, featuring high efficiency, and robust and stable construction.
The milling machines perform both flat (e.g. cutting shapes out of sheet metals, drilling on the basins of two-dimensional drawing), and three-dimensional milling tasks (e.g. preparation of models for casting, laminating, thermal forming). In milling works, in which a number of tools are used, the routers are equipped with systems of automatic tool changing with storage. Automatic tool changing is available in linear or rotational version, depending on the size of the table and the customer's needs in terms of machine efficiency. Industrial machines are equipped with suction foot or suction hood. It is an effective means of dust extraction from the milling station. Suction hood may be set automatically on different heights, depending on the lenght of the attached tool, so that secure the most effective dust extraction.
Large area milling machines tables may be executed in the basic version, that is T-slot tables. The most common, however, are vacuum tables, facilitating very strong fixation of large format materials, without the need to use mechanical fixation.
If a vacuum tables does not provide sufficient fixation, we provide our customers with hybrid tables. It is a table with very dense T-slots, to which vacuum is supplied. Owing to this, there is a possibility of adhering the large format elements by suction, as well as screwing in smaller elements, fixation devices or additonal equipment, e.g. rotary axis.
As a standard, vacuum tables are equipped with one or two vacuum pumps from Becker company, featuring efficiency of 250m3/h. This solution brings both high performance and low noise emission.
Large area milling machines are always executed in configuration with travelling gantry, with double-sided drive, servomotors and electronic compensation unit of the gantry angle.
Kimla company manufactures milling machines not only in standard version, but also in a special version with pneumatic conveyor, with automatic loading and automatic unloading.
