Overview
The DN Solutions PUMA 5100LYB is a large-format multi-axis turning center that combines a Y-axis and a sub-spindle (B in the model designation) with a long-bed configuration for processing complex parts completely in a single setup. It targets manufacturers who need to turn large-diameter parts with off-center features — the kind of work that on a simpler machine would require a lathe, then a VMC, then a second lathe operation. The 5100LYB collapses that into one machine.
The main spindle runs an A2-8 nose driven by a 22 kW (30 hp) motor producing 398 Nm (293 ft-lb) of torque at speeds up to 3,500 RPM. The Y-axis adds ±52.5 mm (±2.1 in) of off-center travel, enabling true off-center milling, contoured pocket milling, and off-axis drilling that the standard X/Z configuration cannot reach. Combined with the 12-station live-tool turret at 3,500 RPM, the LYB can complete parts with radial slots, angled holes, eccentric bores, and contoured features without leaving the machine.
The sub-spindle (B axis) carries a 15 kW (20 hp) motor at up to 4,500 RPM with an A2-6 nose, allowing second-operation turning and milling on the back face of a part after the main spindle completes the front. Parts exit the machine fully machined on both ends, eliminating manual flip and rechucking operations that introduce alignment error. The through-bore on the sub-spindle is 65 mm (2.6 in), matching standard bar sizes.
The long-bed LY configuration extends Z-axis travel to 1,650 mm (65 in), making this machine suitable for large shaft work, long cylinder components, and extended bar-feed production runs where a standard-length machine's Z-travel would be the limitation.
The control is FANUC 0i-TF Plus with DN Solutions' iHMI interface. Siemens 828D is available. Pricing runs $220,000-$320,000 new depending on options and turret specification.

Strengths & Limitations
Strengths
- Y-axis with ±52.5 mm travel enables true off-center milling, contoured pockets, and eccentric drilling not possible on X/Z-only lathes
- Sub-spindle allows complete part machining in a single setup, eliminating manual flip, rechucking, and the alignment errors they introduce
- 1,650 mm (65 in) Z-axis travel accommodates large shaft work and long bar-feed production runs that shorter machines cannot handle
- Main spindle and sub-spindle with live tooling means complex parts exit the machine fully finished on both faces
- Strong torque and box-way construction maintain rigidity and accuracy even during aggressive Y-axis milling operations
- Reduces work-in-progress inventory and machine queue time by eliminating secondary operations on turned parts with complex features
Limitations
- Complexity of Y-axis + sub-spindle + live tooling demands higher-skill programmers and operators to fully utilize the machine's capabilities
- $220,000-$320,000 price point is a significant investment relative to simpler turning center alternatives
- 9,800 kg (21,605 lb) weight and long bed require substantial floor space and preparation
- Y-axis travel of ±52.5 mm (±2.1 in) covers most milling applications but may be limiting for large off-center features on big-diameter parts
- Sub-spindle maintenance and spindle sync programming add complexity relative to single-spindle machines
- Long lead times for complex multi-axis turning configurations — typically 20-30 weeks from order

Frequently Asked Questions
01
In DN Solutions' naming convention: L indicates a long-bed configuration with extended Z-axis travel, Y indicates a Y-axis (off-center milling capability), and B indicates a built-in sub-spindle for second-operation machining. Together, the LYB configuration delivers the most complete turning and milling capability in a single horizontal turning center.
02
The Y-axis adds ±52.5 mm (±2.1 in) of travel perpendicular to the standard X and Z axes. This allows the live-tool turret to position driven tools off the part centerline for milling features that are not radially symmetric — slots on a flat, off-center holes, angled features, and contoured pockets. Without a Y-axis, these operations would require a separate VMC operation after the lathe cycle.
03
The sub-spindle can provide center support similar to a tailstock for some operations, but its primary purpose is second-operation machining rather than steady support for shaft turning. For long, slender shaft work, a conventional programmable tailstock is still the appropriate support method. The sub-spindle picks up the part after the main spindle completes the first operation and machines the second face.
04
New PUMA 5100LYB machines price in the $220,000-$320,000 range depending on turret specification, tooling packages, chip conveyor, high-pressure coolant, and bar feeder interface. The Y-axis and sub-spindle are part of the base machine rather than optional add-ons. Siemens 828D control also carries a premium over standard Fanuc 0i-TF Plus.
05
Both are multi-axis turning centers with Y-axis and sub-spindle capability in the 10-inch chuck class. The Mazak offers Mazatrol conversational control, which many operators find more accessible for complex programming. The PUMA 5100LYB offers more turning length in the LY configuration. Pricing is similar in the $220,000-$350,000 range. For pure turning length with Y-axis and sub-spindle, the DN Solutions machine is the stronger option.
