A cut-off machine especially suitable for handling tubing and including a machine frame defining a work treatment area, a ram on the frame adjacent the work treatment area mounted for movement through a power stroke by at least two drive members engaging the ram at spaced points, a motor system mounted on the frame, and a drive system interconnecting the motor system and the drive members on the ram. The drive system comprises a pair of flywheels driven by the motor system, a pair of crank shafts 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 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.
In a cut-off machine of the type including a machine frame defining a work treatment area, a ram on the frame adjacent the work treatment area mounted for movement through a power stroke by at least two drive members engaging the ram at spaced points thereon, motor means mounted on the frame, and drive means interconnecting said motor means and said drive members, the improvement wherein said drive means comprises:
