Tos MN 80A athe

TOS The MN 80 A center lathe is a versatile machine designed for machining components made of metal or plastic. It comes equipped with a wide range of spindle speeds, reverse motor run switch, and thread cutting facility. The machine also includes accessories such as a collet chuck attachment that can be operated while the machine is running. The lathe is mounted on a wooden cabinet-type bench with the left-hand section housing the drive motor, the switch to start and stop the motor, reverse the motor run and the fuses.

The carriage consists of a longitudinal slide, cross slide, and swivel tool slide, all mounted on precision-ground and hardened bed ways. The slide feed screws come with indexing collars and adjustable feed screw nuts to eliminate backlash. The four-way tool post is also indexable.

Optional extras for the machine include different types of lathe centers, a drilling plate for round work, a faceplate with four reversible jaws, and various collet chucks for gripping materials of different diameters. The machine is also available in different versions with electrical equipment wired for different three-phase voltages, 60 Hz frequency, and surface finish suited for service in tropical climates.
