J.Adolf Bauerle, a German company founded in 1855 and based in Oberkochen, Württemberg, were well known for their range of tool and cutter grinders. During the late 20th century one of their most popular and widely sold models was the Type UWS, a machine delivered complete on a floor stand with built in tool and accessory storage. Fitted to the left-hand side of the stand's top face was a screw-driven table with, on top and sitting on a swivel base, a second table machined with a full-length, V-edged way on its top surface and (running on ball bearings), free to be moved to and fro by hand. To assist the operator a small hand knob was fitted while two stops, held in a front T-slot, allowed the travel to be limited to exactly that required. Fitted to the top table - and able to be adjusted and then locked into position on the ways - was a universal swivelling and tilting indexing head that carried a milling-machine-like arbor on which to mount work. The arbor could be had in diameters of 16, 24, 25 or 30 mm (and various inch sizes) each complete with a set of hardened spacers. The arbor was extended at the other end to form an indexing cylinder, this being drilled to produce all the necessary standard divisions. Although the drum indexer had the advantage of giving a greater number of divisions than the usual type of interchangeable notched wheels (as used on many competing machines), it did require the indexing plunger to be loosened and slide into alignment with the chosen set of holes. Available as an extra was a tailstock and centre to support the end of the arbor when longer or heavier jobs were mounted. The top table could be swivelled through 360°, had a travel of 300 mm (12") and, using the lower screw-feed table, fed in and out through 190 mm (7.5"). Mounted to the side of the table was a large diameter column that could be elevated through a range of 230 mm (9") by a top mounted handwheel - the lower telescopic section being protected from grinding dust by bellows. At the top of the column a casting was bored through to accept a round bar on one end of which was the grinding head and on the other, driving by a V-belt, a powerful 0.75 h.p. 2800 r.p.m. 3-phase motor. Three speeds were provided - 3200, 4500 and 6000 r.p.m. - the range being designed to cope with grinding wheels from small up to a maximum of 175 mm (7"). With the column able to be rotated through 360°, and the head assembly turned within its housing though 50° each side of upright, most tool-grinding jobs could be set up with relative ease..
