Turner Universal Tool and Cutter
Grinding Machine
Catalogues are available for these machines

Made by the Turner Manufacturing Co. at their Wulfruna Works in Moorfield Street, Wolverhampton, this was a copy or licence-built version of the American Greenfield "Universal Grinding Machine". Turner had wide engineering interests and, in addition to the manufacture of capstan and centre (engine)  lathes, shapers, arbor presses and machine-tool accessories, were also involved in the motor trade having once been builders of cars and trucks.
Weighing around 638 lbs, the tool & cutter grinder was, for its type, a rather unusual design and carried on a cast-iron base a round column that supported a milling-machine-like knee topped by a rack-and-pinion driven table. On top of the main table was a 28" x 5.75" sub table that could be set over by means of a small handwheel, a degree scale being engraved on the end face
As well as being able to be raised and lowered, the knee could also be rotated around the support column - the former movements using a bevel-gear arrangement controlled by a large handwheel equipped with a good-sized micrometer dial.  Advertised as the "
Turner  9" x 18" Motor Driven Universal Tool and Cutter Grinding Machine" it would have been manufactured in the period circa 1900 to the 1930s, though the short V-belt drive to the spindle by a top-mounted motor showing that the example in the colour pictures below would have post 1931 when this type of drive become more widely used. Interestingly, the original American-made machine was advertised until at least 1931 with a separate, complex and doubtless expensive ceiling-mounted countershaft unit. It appears that, in this respect, the Turner had been successfully updated and was doubtless far cheaper to build as a complete, working machine.
With a maximum swing of 9", the Turner could admit 15" between centres, had 18" of longitudinal travel, 8.5" in traverse and 7" vertically. With a countershaft running at 600 r.p.m. the main spindle was intended to be run at 3000 r.p.m. and the internal spindle (with its tiny wheel) at up to 11,000 r.p.m.
A surviving example of the Turner has a range of optional equipment, doubtless similar to that available for the Greenfield and originally held within a fitted hardwood accessory cabinet also issued with the American model. Items supplied as part of the ordinary equipment included: complete countershaft equipment on the early flat-belt drive models; an internal grinding spindle; swivel-base tilting machine vice; indexing attachment with division plates; bevel and face-cutter holders; taper shank butt mill holder; a 3-jaw chuck mounted on a swivel holder; holder for gear cutters (one 10-tooth index, one 12-tooth index and one 13-tooth index); pair of centre heads - one flange centre with pulley, two 1/2" plain centres, two knee clamps and three dogs; adjustable tooth rest; tooth rest holder for spiral cutters; d table; holder for hand table; cup wheel holder and wheel; right-hand wheel holder; lefty-hand wheel holder; malleable box spanner; 3/8" engineer's spanner; carriers; centres; assorted grinding wheels; the necessary wheel guards and, on late models, full electrical equipment. Also available (but not listed in the standard accessory range) was a table-mounted electrically-driven wheelhead had by which means cylindrical grinding could be carried out
A full technical description of the Turner, taken from the original advertising sheets. can be found on the Greenfield pages..
