MTE XXL milling machines matter again in tool and mould making

Editor: Barbara Schulz

Germany/Spain - Gunther Borbonus heads the German subsidiary of the Spanish machine tool manufacturer MTE in Montabaur. In 20 years the company has sold 1,100 large milling machines all over the world and currently expects increasing demand from tool and mould makers. The company will also be exhibiting at Metav 2016 in Düsseldorf, Germany.

ETMM: Who uses your large bed-type and travelling-column milling machines?

Gunther Borbonus: Basically, all those companies that have to machine large components, including, for example, rail producers, contract manufacturers, and other metalworking plants. The fields in which there’s currently most of the catching up to do are tool and mould making. One reason at the time was the advance of 3D design software, which had largely superseded conventional prototyping. In the second half of the new millennium’s first decade, this led to a severe slump in investments in large machinery. And it’s precisely that investment backlog that would now appear to gradually be melting away.

ETMM: How high is the vertical integration of your manufacturing capabilities?

Borbonus: Very high indeed, since MTE produces everything in terms of mechanical components and complete cast assemblies in-house. This is crucial in assuring the requisite stability and precision. The only outsourced components are control cubicles, drives, control systems, and casings. Nonetheless, we are always able to meet tight delivery deadlines. A travelling-column machine, for example, takes us three to four months to make.

ETMM: What gives your machines the required rigidity?

Borbonus: In part, the machines consist of top-quality spheroidal graphite cast iron, GGG 70, which lends them a high degree of rigidity, and thus of precision and long-term accuracy as well, while simultaneously providing optimum vibration damping.
