CNC machine tools for metal, steel, aluminum, brass, copper
Metal materials, ie aluminum, copper, steel, brass, are materials that can be machined on many machines manufactured by our company. Sheet metal parts are most efficiently processed with a laser cutter. It is the undisputed leader when it comes to the efficiency of cutting sheet metal parts from these materials. These are solutions that ensure high efficiency at a large scale of production, but with a relatively high investment scale. The fiber laser works great with these materials up to a dozen or so millimeters thick about 15-20 mm. Above this thickness, a great solution is to use a slightly cheaper solution, i.e. a Waterjet, which shows its capabilities where laser cutting capabilities end. Cutting with waterjet is slower however it gives much greater versatility, because firstly we can cut materials of any thickness up to 200 mm and apart from metals it is able to cut out other materials such as glass, ceramics, composite materials, stone - it is a much more universal solution in addition, it is a device with a clearly lower price in relation to the laser, but you have to accept the lower efficiency. For universal applications, a much better solution is available that ensures the ability to process the largest possible range of materials. In the case when we care about the maximum metal cutting efficiency up to 20mm, the laser is an unrivaled solution. Lasers cut black steel to a certain thickness using a shielding gas in the form of nitrogen, while above a certain thickness, cutting takes place in the oxygen shield. The thickness of oxygen must be used depends on the power of the laser source. The greater the source power, the thicker black steel sheets can be cut with nitrogen. Nitrogen cutting is much more efficient and does not leave oxide deposits on the surface of the material being cut. This solution is more favorable for technical, quality and economic reasons. Cutting steel in oxygen is slower but it allows cutting much thicker materials. Other metals such as copper, aluminum, brass, and stainless steel are always cut in the nitrogen shield. In some special cases where we do not care about the quality of the surface, it is possible to cut with air, which eliminates the cost of the cutting gas, thus reducing the cutting costs
Mechanical machining of details can take place both on large-format machining centers and milling machines. Milling machines manufactured by our company are milling tools for machining with high spindle revolutions, i.e. the so-called HSM (High Speed Machining) technology. They are devices with a parallel configuration with a moving table. Due to the fact that the movable table moves on the body and the spindle in the X-axis also moves on the body, non-rigidity is not added as in the case of machines with serial kinematics. Machines with serial kinematics, ie large-format machining centers allow to obtain large work areas while limiting the size of the device, one such solution is already less rigid. They are perfectly suited for processing non-ferrous metals with high efficiency, however, steel processing is possible to a limited extent. However, in many applications such as chamfering before welding and cutting openings for control panel elements and cutting out of composite or laminar elements consisting, among other things, of thin sheets, no less a problem. These machines can be used for production purposes in the manufacture of components, e.g. in the industry of door and garage door production, i.e. metal-foam sandwich panels. Machines with a driving table - steel milling machines are used for the production of injection molds of dies and stamping dies and for the very quick processing of aluminum. We owe this opportunity to high spindle speeds, which are standard 24 000 revs/min (optional 40,000 rpm, 50,000 rpm and more). Both milling machines and large format machining centers are available in the version with linear drives, which provides a positioning resolution of 1 nm and an accuracy of 5 μm on the subway. This technology eliminates the process of wear of the drive ratio, which ensures high quality and accuracy machines right after purchase and after 10 years of work.
