CNC Heavy Duty Precision & Big Bore Lathe (18” Bed) | SPB Series | MYDAY
The MYDAY SPB Series is a CNC heavy-duty precision and big bore lathe designed for demanding turning applications requiring high rigidity, large spindle bores, and reliable machining performance. Available in SPB670, SPB770, and SPB840 models, the series features a rigid 18-inch (460 mm) flat bed, swing over bed from 670 to 840 mm, and distance between centers from 1.5 to 5 meters.
Spindle power is transmitted through a pulley, belt, and 4-step gearbox, providing high torque and a wide spindle speed range for both precision turning and heavy-duty cutting. With spindle bore options of 4", 6", and 9", the SPB Series is well suited for machining large shafts, pipes, tubes, rollers, and other medium-to-large industrial components.
Combining CNC precision, big bore capability, and robust flat-bed construction, the SPB Series provides a versatile and reliable machining solution for general metalworking, steel, energy, heavy equipment, and other demanding industrial applications.
