DN Solutions PUMA 5100 MB

The DN Solutions PUMA 5100 MB is the standard-bed, 21-inch chuck powerhouse in the 5100 family. It's designed for shops machining the biggest, heaviest chucking work — large forgings, castings, and weldments up to 650 mm (26 in) in diameter — where you need maximum clamping force and torque in a machine that doesn't take up your entire shop floor.

The 45 kW (60 hp) spindle cranks out 2,958 Nm (2,182 ft-lb) of torque, the highest in the standard-bed 5100 lineup. The 21-inch chuck grabs big workpieces with the kind of authority that keeps them locked down during heavy interrupted cuts on rough castings. At 1,500 RPM max, the spindle still delivers well over 2,000 SFM at full swing diameter — plenty for carbide inserts in steel and iron.

Max turning length is 952 mm (37 in) with 1,105 mm (44 in) of Z-axis travel. This is a chucking machine, not a shaft machine. The standard bed keeps the footprint reasonable while the 362 mm (14 in) X-axis travel accommodates the full 26-inch swing. The 12-station turret with 4,000 RPM live tooling handles secondary operations without pulling the part.

At 10,750 kg (23,700 lb), it's the heaviest standard-bed 5100 variant, reflecting the larger spindle assembly and chuck. Box-way construction provides the rigidity and vibration damping that big-bore turning demands. You won't feel flex or chatter when you're taking 4-5 mm depth of cut in gray iron at 300 SFM.

The FANUC 0i-TF Plus control runs the show. It's the same control across every PUMA in the catalog, which makes fleet management and operator training straightforward. For shops focused on large-diameter chucking work — valve bodies, pump housings, large flanges, and heavy fittings — the 5100 MB puts the right combination of grip, power, and rigidity in one package.
