For 50 years, the Dutch manufacturer of portal milling machines and machining centers Unisign has been realizing machine concepts that are constructively adapted to special machining requirements. An in-house production depth of over 80 percent ensures that the know-how remains within the company. Among other things, all workpieces requiring high precision are manufactured in-house. In the field of grinding, the company relies on the Swiss grinding machine specialist Kellenberger.

When Bart van Ruth founded his design office exactly 50 years ago, he had the goal to find technological solutions for productivity improvements. The development of his first own product, a vertical, column-moving CNC drilling machine with a fixed machine bed, brought success especially on the German market. In 1988, the first gantry milling machine for 5-sided machining of workpieces was presented.
