In the years prior to WW2 Hauser were well established and offered a wide range of highly-effective models. So popular were these, and in such great demand, that even in Germany (home to some very fine machine tools) the Hauser agents, Hahn & Kolb offered larger two-column jig borers made by the Hille Werke Company in Dresden under a Hauser license.
Hille were an important machine tool company whose original speciality, from the late 1800s, was boring machines - from simple table-top to large vertical, multi-spindle and radial types. During the 1930s they expanded into special borers (offering several vertical and horizontal models) and fine boring machines for finishing IC engine blocks. In 1935 Hille bought a license from Hauser in order to obtain details of their screw-correction and other measuring systems. However, the vertical movement of the boring-head (twin-column models) was also done by screws but, as it was impossible at the time to produce two exactly the same, the solution arrived at was to lift the head up and then lower it onto specially made, very accurate packing blocks. After WW2 Dresden was in the Russian-controlled zone and, when machine-tool manufacture started again in the early 1950s, Hille was taken into the WMW group under GDR control. For a long time they offered just one size of jig borers though eventually, in the 1960s, one more model was added, a single-column machine with an optical measuring system..
