Hardinge DSM-59, DSM-59R and DV-59 (also advertised as the "DSM five-nine" and also applying to the HSL-59 short-bed version). These lathes were identical save for the equipment bolted to the bed. A tailstock and compound slide rest produced the Super-Precision plain-turning DV-59 and with a turret head and cut-off slide and other equipment the DSM-59 "Second-operation" Model.
