Burchardt Maschinenbau was a small manufacturer of the 1950s and 1960s based in what was then the Western Sector of Berlin. Little known outside their native land, they offered a range of lathes from miniature precision types to conventional geared-head and bigger "Leit and Zugspindel" models (with a 180 mm centre height) together with a number of metal-sawing machines.
Shown below (and probably from the 1950s ) is the 50 mm centre height Model DU-01 bench lathe. Arranged for underdrive, it was mounted on a vertical bar that socketed into a cast-iron plinth with tunnels front and back to allow clearance for the round drive belt. The 10 mm bore headstock spindle ran in adjustable bronze bearings with the M20-threaded nose taking made 10 mm collets with an 8 mm thread. The 300 mm long, cantilevered bed was formed from an almost square-section steel bar turned to present bevelled faces to front and rear. As was common with this class of lathe, two tailstocks were provided, one for ordinary centres and the other for the use of collets - in this case from the headstock - and one of them would originally have been lever-operated. Although intended for watch and clockmakers' use, detailing on the compound slide rest looks to have been comparatively crude with the micrometer dials having widely-spaced markings and coarse knurling around their periphery.
If you have a Burchardt lathe of any type, or know anything of the company, the writer would be interested to hear from you.
