OERLIKON DMI MANUAL LATHES

Technical Description

The Oerlikon DMI is a precision manual engine lathe featuring a 24-inch swing capacity, making it suitable for medium-sized machining operations. This Swiss-manufactured machine represents the industrial-grade tooling equipment produced by Werkzeugmaschinenfabrik Oerlikon, known for robust construction and precision performance. The DMI model incorporates several notable design features characteristic of European precision lathes from this era. The machine is equipped with a substantial spindle motor and precision spindle bore, providing the rigidity necessary for accurate turning operations on workpieces up to 24 inches in diameter. The lathe includes a compound rest assembly with fixed positioning capabilities, enhancing versatility for various cutting operations including taper cutting when equipped with powered slide features. Key specifications include multiple threading pitch options supporting inch, metric, DP, and module measurements, accommodating diverse manufacturing requirements. The machine features precision scales for macro positioning on cross and compound feeds, enabling accurate tool placement prior to the digital readout era. The stout tool post design ensures reliable tool holding during demanding machining tasks. As a manual lathe, the DMI requires operator control for feed rates and spindle speed adjustments, offering machinists direct control over the cutting process. The machine employs a leadscrew reverse mechanism facilitating threading operations without requiring a traditional threading dial. With approximately 8,000 pounds of mass and 20 horsepower output, the Oerlikon DMI delivers the stability and power necessary for sustained production work and precision prototype manufacturing.
