Grinding machine AI Hembrug U2


The Hembrug U2 tool and cuttergrinder is a very universal grinding machine. It was build as a tool grinder but it was also widely used for other grinding jobs. It's quite heavy for a toolgrinder (aprox 1000 kg.) this makes it very stable and versatile. There are a lot of optional tools and holders available.

The hembrug grinder is a copy from the Cincinatti #2 universal toolgrinder. After the second world war the production of guns and artillerie got down to a minimum and Hembrug needed other sources of income. The production of metalworking machines was expanded. In the showroom were lathes, grinders, shapers and mills. There was not a wide range of models, but within the models there were many changes. The production batches were relative small and this allowed Hembrug to include customer requests into the design.

The predesessor of the U2 was the U1. The main difference is that the crosslide is not on rollers. The U2 has rollers so it is possible to use a copying attachment. Special forms in milling tools can be ground and with a special setup it is possible to grind camshafts.
