Reliable machining Laser or 5-axis machine? Two options for maximum precision
At AMB 2022, Kern will be presenting for the first time two machines that are characterised by high precision machining, but which are based on two completely different technologies: the latest generation of the Micro HD five-axis machining centre and the Femto E3 laser machining centre.
Anyone who wants to mass-produce components with process-reliable accuracies in the μm range should take a look at the machines Kern Microtechnik showcases at AMB, Stuttgart/Germany.
With the Micro HD and the Femto E3, the company will show two innovative machining centres in action, which are similar in terms of colouring and distinguished by the highest precision, but differ significantly in the technology used.
On the Kern Micro HD, for example, the company machines mould inserts for filter housings that are milled and ground in one clamping. This means that the components are first machined and then brought to the highest surface quality at individual points via coordinate grinding with five-axis cycles. In the final result, the components achieve a precision of less than 1 μm and surface qualities in the single-digit nanometre range on various contact surfaces. The usual manual polishing is no longer necessary.
Also to be experienced live: the production of carbide press punches. For these and similar components, the new Kern Femto E3 laser machining centre proves to be the ideal production solution. The machine processes hard materials with ultra-short pulse lasers with the highest dimensional accuracy of +/-3 μm and without heat input. Since the laser is not subject to wear, there are also no tooling costs. With surface qualities of up to Ra=0.2 μm, the new Kern technology produces highly productive and process-stable materials. Compared to manufacturing by die-sinking EDM, a reduction of the complete machining by up to 75 percent can be achieved.
The stand is also of interest to trade fair visitors who are interested in texturing surfaces. Because the Femto E3 can also perform this task quickly and easily on a wide variety of materials.
