IXION Mill/Drill - by Otto Häfner - If you have a machine tool by Otto Hafner, the writer would be interested to hear about it
Made by Otto Häfner in Hamburg, Germany, the 342 kg Ixion milling and drilling machine was very heavily built and modelled along lines established by Taiwanese and Korean makers whose inexpensive and now ubiquitous Mill/Drills began to appear on the market in the early 1970s. The very long established German machine-tool distributors Hahn & Kolb also listed the machine - which was also sold under the Maxion brand. Ixion was a manufacturer of small table-top and larger floor-standing drilling machines and, during the 1980s (and following the example of other makers, for example, Fobco in the UK) offered a compound-table to fit their heavier models. With a powerful 3-phase motor mounted at the back the drive was brought forwards by V-belt from a 5-step pulley to an intermediate 5-step idler pulley and from there to the spindle by 32 mm wide Poly-V belt - the standard-fit 2-speed motor giving a total of 10 speeds from 120 to 2160 r.p.m. Far Eastern machines, invariably fitted with a single-phase motor, also used an intermediate pulley to give between 9 and 12 speeds with much the same range - though always with V-belts throughout. Fitted with a 610 x 24 mm (24" x 9.5") table with travels of 353 mm (14") longitudinally and 165 mm (6.5") in traverse, the Ixion had both a quick-action drilling feed for the 120 mm (4.75") travel spindle and a particularly slow and delicate worm-and-wheel driven slow feed. Like many Swedish Arboga millers, the Ixion enjoyed the advantage of a compound table that could be unbolted from the T-slotted base plate and used beneath other drills or on other machine tools. Removal of the table also gave an increase in clearance beneath the spindle nose - this was normally 585 mm (23") - and hence the chance to mount special vices or other items. Instead of the crude rack-and-pinion head-elevation mechanism used on the majority of competing examples (which allowed the head to loose its alignment during long-travel movements) the Ixion was fitted with a bevel-box at the foot of the column that ensured everything stayed in line (a design identical to that used on the rather good Korean-built "Naerok"). Feed screws were metric and, according to a satisfied owner, the whole machine demonstrated spot-on accuracy in use.
