CNC Heavy Duty Oil Country & Big Bore Lathe (32” Bed) | SOH Series | MYDAY
The MYDAY SOH Series is a CNC heavy-duty oil country and big bore lathe engineered for large-diameter, long, and heavy workpieces. Available in SOH1200, SOH1400, and SOH1600 models, the series features a rigid 32-inch (800 mm) flat bed, with an optional 1000 mm bed width with auxiliary guideway for enhanced support and machining stability.
With swing over bed up to 1580 mm and spindle bore options ranging from 6" to 25", the SOH Series provides exceptional flexibility for machining large pipes, tubes, long shafts, rollers, flanges, and other heavy industrial components. Distance between centers is available from 2 to 10 meters as standard, with extended bed lengths customizable to meet specific workpiece and machining requirements.
The 4-step spindle system provides high torque and a wide spindle speed range for heavy-duty turning, threading, and large-diameter machining. For long pipes and oilfield applications, an optional double chuck system provides secure workpiece clamping and support on both sides of the headstock. A Ø290 mm rotary quill tailstock is also available for applications requiring enhanced support for large and heavy workpieces.
Combining large swing capacity, an exceptionally large spindle bore, rigid flat-bed construction, and flexible CNC configurations, the SOH Series is ideally suited for oil & gas, steel, energy, shipbuilding, heavy equipment, and other demanding industries. Optional C-axis control, power turret, milling, and boring devices further expand the machine’s capabilities for complex and customized machining applications.
