ERLANGER, KY - Romi Machine Tools, Ltd, an industry leader in turning machine technology, has built a reputation providing customer-driven solutions to a broad array of precision turned-part challenges. The M Series of Combination lathes is yet another step in providing these solutions ever-more flexibly. The M Series is ideal for today's mixed-volume, short-run, JIT operations as well as dedicated, high-volume applications.

With a swing of 20", the M 20 combines high performance turning and large machining capacity within a compact 124.02" x 64.96" space-saving footprint. Rapid traverse rates of 394 imp (X axis) and 295 (Z axis) mean accelerated machine cycle times and reduced non-cut time, which increases overall throughput. Also increasing cycle time is an optional automatic electric turret offering a fast 0.48 second index, station-to-station. The turret holds eight tools with pockets for square tool holders and bolt-on I.D. tool blocks.

The M 20 has a rigid cast iron "H" bed design. All guideways are induction hardened and ground. They feature a Turcite-coated carriage and cross-slide that move smoothly on the solid bed and saddle guideways, thus ensuring superior rigidity, accuracy, cutting tool performance and long machine life. The M 20 offers three bed-length options: M 20 by 40, M 20 by 60 and M 20 by 80. Distance between centers is, respectively, 43.15", 62.84" and 82.52"

The spindle. A new belt-driven cartridge-style gearless headstock featuring a high-torque 15 hp AC GE Fanuc "P"-type spindle motor with a variable speed drive permits full horsepower at spindle speeds as low as 275 RPM. Three spindle options allow you to match the spindle speed and size to specific production needs. A2 spindles feature rigid mounting, larger through-hole capacities and higher RPM, while Dl Camlock spindles offer quick chuck changing between three- and four-jaw chucks. The A2-6" has a through hole of 2.56" and a speed range of 3 to 3,000 RPM, while the A2-8" and Dl-8 have a through hole of 3.15" and a speed range of 2 to 2,200 RPM.

To assure the rigidity required for heavy-duty cutting, the spindle is supported by angular contact ball bearings at the nose and a double row of cylindrical roller bearings at the rear. The spindle cartridge is lubricated for life, and the spindle design eliminates the need for oil recirculation or a refrigeration systems to maintain spindle temperature. The result is years of reliable performance with reduced operating and maintenance costs.
