Overview

The DN Solutions PUMA 3100 Y is the standard-bed Y-axis variant in the 3100 turning center platform. It adds a programmable Y-axis to the proven 3100 mill-turn package, unlocking off-center milling operations that C-axis interpolation alone can't handle cleanly. If you've been running a GT 3100 M and sending parts to a VMC for off-center holes, flats, or keyways, this machine eliminates that second operation.

The main spindle delivers 26 kW (35 hp) with 1,123 Nm (828 ft-lb) of torque at up to 2,800 RPM through a 12-inch (305 mm) chuck. Max turning diameter is 376 mm (15 in) with 725 mm (29 in) of turning length on the standard bed. These numbers match the GT 3100 M exactly — the Y designation adds the Y-axis without changing the base turning capability.

The Y-axis provides +/-52.5 mm (105 mm total, 4.1 in) of off-center travel with dedicated servo control. Combined with the 12-station turret running live tools at 5,000 RPM and full C-axis positioning, you can mill flats, drill off-center holes, cut keyways, and machine hex features — operations that would otherwise require pulling the part and fixturing it on a mill.

Z-axis travel is 830 mm (33 in) and X runs 260 mm (10 in), with rapids at 24 m/min on X, 30 m/min on Z, and 10 m/min on Y. At 6,050 kg (13,338 lb), the machine carries a bit more mass than the non-Y variant due to the additional Y-axis slide mechanism. The footprint is 3,865 mm (152 in) long by 2,102 mm (83 in) wide.

The FANUC 0i-TF Plus control handles the 4-axis programming (X, Z, C, Y) with standard G-code Y-axis commands. For shops doing production runs of parts that need both turning and off-center milling features, the PUMA 3100 Y consolidates two machines into one setup — and that's where the ROI lives.

Strengths & Limitations

Strengths

Y-axis eliminates secondary VMC setups for off-center drilling, flats, and keyway milling
1,123 Nm of spindle torque handles aggressive roughing in alloy steels and stainless
12-inch chuck provides solid clamping for parts up to 376 mm diameter
Live tooling at 5,000 RPM combined with Y and C axes creates a true mill-turn center
Standard-bed footprint keeps the machine compact at 3,865 mm long
FANUC 0i-TF Plus control with proven Y-axis programming support

Limitations

2,800 RPM spindle speed limits surface speed on small-diameter aluminum finishing
725 mm max turning length constrains longer shaft work — choose the XLY or ULY for extended parts
Y-axis adds $15,000-$25,000 over the non-Y GT 3100 M variant
105 mm total Y-axis travel limits the offset distance for milling operations

Best For

Shops producing turned parts with off-center holes, flats, keyways, or hex features that currently require a second VMC operation Production environments running flanges, couplings, and fittings with both turning and milling features Facilities that have outgrown 2600-class lathes and need Y-axis mill-turn on medium-to-large parts Automotive and hydraulic component manufacturers with complex turned-and-milled parts Job shops looking to consolidate turning and milling into a single setup for faster throughput

Frequently Asked Questions

01 What does the Y designation mean on the PUMA 3100 Y?

The Y means this machine has a programmable Y-axis that moves the turret off-center from the spindle axis. This allows true off-center milling, drilling, and tapping operations that C-axis interpolation alone can't perform accurately. It turns the lathe into a full mill-turn center.

02 How does the PUMA 3100 Y compare to the GT 3100 M?

The spindle, chuck, bed, and turning specs are identical. The Y adds a 105 mm Y-axis for off-center milling operations. If your parts only need C-axis milling (on-center holes and features), the M saves money. If you need off-center features, the Y eliminates secondary setups.

03 What does a PUMA 3100 Y cost?

New machines run $150,000-$195,000 depending on options. The Y-axis adds a premium of roughly $15,000-$25,000 over the GT 3100 M. The payback comes from eliminating secondary VMC operations on parts with off-center features.

04 Can I program the Y-axis with standard G-code?

Yes. The FANUC 0i-TF Plus control supports standard G-code Y-axis commands. Most CAM systems (Mastercam, ESPRIT, GibbsCAM) support Y-axis lathe programming with dedicated post processors for DN Solutions PUMA machines.
