DN SOLUTIONS PUMA 400 B HORIZONTAL MACHINING CENTER

Technical Description

The DN Solutions PUMA 400B is a CNC horizontal turning center engineered for precision production work with substantial workpiece capacity. This machine features a maximum turning diameter of 21.7 inches and turning length of 41 inches, accommodating bar stock up to 4.5 inches in diameter. The 15-inch hydraulic chuck with 28-inch maximum swing clearance provides excellent accessibility for part loading and tool changes. The spindle delivers 50 horsepower at speeds up to 2,000 RPM, generating sufficient torque for aggressive metal removal operations. The machine is equipped with a 12-station automatic turret capable of holding multiple cutting tools, enabling efficient multi-operation cycles with minimal setup time. The dual-axis control system offers X-axis travel of 14.3 inches and Z-axis travel of 43.5 inches, both with rapid traverse rates of 630 IPM, ensuring responsive positioning and reduced cycle times. The machine utilizes a Fanuc 21i-TB CNC control system, providing advanced programming capabilities and reliability in production environments. Standard equipment includes a hydraulic tailstock for between-centers work, coolant system, chip conveyor, and programmable tool presetter integration options. The robust 21,000+ pound construction minimizes vibration during cutting operations, supporting consistent tolerances and surface finish quality. This configuration makes the PUMA 400B suitable for automotive, medical device, and general precision machining applications requiring automated bar-feeding operations and complex turning sequences in a compact footprint.
