Hofmann Precision Dividing Heads Technical Data
Technical documentation and specifications for Hofmann precision dividing heads, covering the UTH (Universal), HTH, and NTH (Semi-Universal) models manufactured by Maschinenfabrik Dionys Hofmann GmbH. This workshop manual details manually controlled indexing equipment with center heights ranging from 80 to 700 mm and load capacities up to 12000 kg. Specifications include direct indexing via 24-notch engagement, indirect indexing with a 1:40 worm gear reduction ratio, and differential indexing capability for achieving divisions up to 1000. The dividing heads feature hardened spindles, precision needle roller bearings, and oil bath lubrication systems for reliable long-term operation. Precise angular positioning is enabled through micrometer dial adjustment calibrated in degrees, minutes, and seconds, with 10-second vernier accuracy for demanding tolerance requirements. This reference material supports proper installation, calibration, maintenance, and troubleshooting across all three model variants.
