<p>A cut-off machine especially suitable for handling tubing and including a machine frame (11) defining a work treatment area (12), a ram (22) on the frame adjacent the work treatment area mounted for movement through a power stroke by at least two drive members (40) engaging the ram at spaced points, a motor system (30,32) mounted on the frame, and a drive system (42) interconnecting the motor system and the drive members on the ram. The drive system comprises a pair of flywheels (36) driven by the motor system, a pair of crank shafts (40) driven by the flywheels through a clutch associated with each flywheel, and a crank portion on each crank shaft journalled in the ram so that the ram is moved through an orbital path in response to rotation of the crank shafts. A gear train (52 54,57) is positioned between the crank shafts to synchronize the rotation of the crank shafts to ensure that the ram moves in a translatory manner through its orbital path. <IMAGE></p> |
