Holke are a long-established Spanish maker of milling machines, based in the north of country, in the Basque region, an area traditionally associated with the manufacture of machine tools. The Company was founded by a German émigré, Otto Holke, in 1934, and became the first Spanish maker of milling machines. As with many engineering companies, over the decades several restructurings took place, the present incarnation being listed as Enrique Holke, S.L. and owned by Enrique Helmut Holke Almazan.Sale. Today the Company's activities include the repair and manufacture of machining centres, CNC and conventional millers and the sale of used machines.
A virtual copy of the Bridgeport Series 1, the Holke was but one of eighteen or so other copies of the American machine made in Spain from the late 1950s until the 1970s, the better-known of these including Lagun, Metba and Kondia. The Holke version was well-made and widely exported and - apart from a larger F-11-V model -  appears to have been offered in a single version that included the option of accessories duplicating almost all those offered by Bridgeport.
Fitted as standard with a manually-operated table having three 16 mm T-slots on a spacing of 63 mm and a working size of 1120 x 255 mm, the maker hinted that other sizes were available, but failed to list them. Longitudinal travel by hand was 815 mm, this, rather unusually, increasing (by 100 mm) instead of decreasing when power feed was fitted. Travel in traverse was 400 mm (by hand or, at extra cost, under power) and vertically (by hand only) 410 mm. When fitted with power feeds - "rapids" was also included - a choice was offered of 12 mechanically-driven rates from 15 to 230 mm/min or, with the same range, steplessly with electronic control -  this fitting being applicable to both longitudinal traverse feeds. Feed screws, supported at each end in what are believed to have been sealed ball races, ran though bronze nuts.
A single vertical head was offered, this being of the simple V-belt type that, driven by a 1.5 h.p. motor, had eight speeds from 72 to 2480 r.p.m. - though the option of a 2 h.p. motor was also available. Manufactured from a Cr-Ni steel, the main spindle was case hardened, ground all over, equipped with a 40 INT nose (or 50 INT to special order) and held inside a quill that was plated with hard chrome on its outer surface. Sliding inside a honed housing, the quill was moved by both a fine-feed handwheel, working through worm-and-wheel gearing, and by quick-action lever for drilling. Power feeds were fitted to the spindle as part of the ordinary specification, these being automatically disengaged at the top and bottom of their travel, the three rates being 0.04. 0.08 and 0.2 mm/per rev.
Supplied with each new miller was a complete electrical installation, coolant equipment, a grease gun, a set of service spanners, an Instruction and Parts Manual and a tolerance verification chart. A wide range of accessories was offered including a universal slotting head with 3-inches of  travel and five speeds; 320 and 400 mm rotary tables with indexing plates and tailstocks; a universal indexing head; various machine vices including rotary-base, mechanically and hydraulically operated types; an externally mounted high-speed (4 : 1 ratio step-up) attachment for the spindle end; spacing rings 100 and 180 mm thick to lift the turret assembly; a right-angle head and arbor assembly for horizontal milling; a "multi-angle" swivelling head for fine work; mountings to hold dial indicators and precision length rods; optical measuring equipment with precision scales and measuring rods 400 mm  long  for  the  transverse travel and 800 mm for the longitudinal; a centralised lubrication system  for the slideways; protective bellows for the transverse slide; special swarf and coolant trays; hydraulic copying equipment (by the English Hepworth Company; a planetary  grinding  unit by Precise (their Model JEL with speeds from 15,000  to 45 ,000 r. p: m.); low-voltage light units and assorted collet sets, drill chucks, T-bolts and reducing and adapter sleeves for the spindle socket..
