Overview

The Haas UMC-750SS is the super-speed variant of the UMC-750, pairing 762 x 508 x 508 mm (30 x 20 x 20 in) of travel with a 12,000 RPM inline direct-drive spindle. The SS designation means faster spindle speed, faster rapids, and faster tool changes compared to the standard UMC-750, making this the machine of choice for shops running aluminum-dominant 5-axis work where cycle time reduction translates directly to profit.

The 22.4 kW (30 hp) spindle delivers 122 Nm (90 ft-lbf) of torque at 2,000 RPM while spinning to 12,000 RPM. That 48% speed increase over the standard 8,100 RPM gives significantly better surface footage on aluminum with small-diameter end mills, improving finish quality and reducing cycle times on profiling and contouring operations. The CT40/BT40/HSK-A63 taper options maintain tooling flexibility.

The trunnion carries a 630 mm (24.8 in) platter with seven T-slots and a 340 kg (750 lb) capacity, or 136 kg (300 lb) with the optional pallet pool. The B-axis tilts from +120 to -35 degrees with 2,514 Nm of continuous torque, and the C-axis provides full 360-degree rotation with matching torque. Maximum part swing is 610 mm (24 in). These are the same robust trunnion specs as the standard UMC-750.

Rapids run at 30.5 m/min (1,200 ipm) on all three linear axes, which is a 33% improvement over the standard UMC-750's 22.9 m/min. The 30+1 SMTC posts 1.6-second tool-to-tool and 2.2-second chip-to-chip times, cutting tool change overhead by roughly 40% compared to the standard model. At 7,711 kg (17,000 lb), the machine has solid mass for vibration control. The UMC-750SS is the highest-performance 5-axis machine Haas offers in the 750-class envelope, and it competes directly with machines costing $100K more from European builders.

Strengths & Limitations

Strengths

12,000 RPM spindle delivers 48% more speed than the standard UMC-750 for faster aluminum finishing and better surface footage
1.6-second tool-to-tool and 2.2-second chip-to-chip are 40% faster than the standard model, cutting cycle time on multi-tool jobs
30.5 m/min rapids on all axes reduce non-cutting time by 33% compared to the standard 22.9 m/min
750 lb platter capacity and 24-inch part swing handle medium-to-large 5-axis workpieces in aluminum and steel
170 °/sec B-axis and 179 °/sec C-axis speeds are dramatically faster than the standard 50 °/sec for quick repositioning
Same 30 HP and 122 Nm torque as the standard model maintains steel-cutting capability alongside the speed gains

Limitations

Base price near $240K is roughly $47K more than the standard UMC-750, requiring volume to justify the speed premium
300 lb pallet pool capacity is less than half the standard 750 lb platter capacity, limiting unattended part weight
12,000 RPM may still feel limiting for shops running very small tools in aluminum; 15K and 20K options cost more
7,711 kg machine weight requires solid floor preparation and rigging for installation

Best For

Aerospace aluminum 5-axis production where cycle time reduction on every part adds up over thousands of pieces Job shops running mixed aluminum and steel 5-axis work that need both speed and torque Automotive and motorsport component manufacturers producing complex 5-axis parts in aluminum alloys Medical device production in titanium and stainless where faster tool changes reduce per-part cost Shops stepping up from a standard UMC-750 or UMC-500 to increase throughput on existing 5-axis programs Production environments using the optional pallet pool for unattended multi-shift 5-axis machining

Frequently Asked Questions

01 What does a new Haas UMC-750SS cost?

Base price starts at around $239,995. With through-spindle coolant, probing, pallet pool, and production software, expect $280,000 to $310,000 for a fully loaded machine.

02 What is the difference between the UMC-750 and UMC-750SS?

The SS version bumps spindle speed from 8,100 to 12,000 RPM, rapids from 22.9 to 30.5 m/min, tool-to-tool from 2.8 to 1.6 seconds, and rotary axis speeds from 50 to 170+ degrees per second. Spindle power and torque remain the same at 30 HP and 122 Nm. The SS costs roughly $47K more than the standard model.

03 Can the UMC-750SS handle steel?

Yes. The 30 HP spindle with 122 Nm of torque at 2,000 RPM is the same powerplant as the standard model and the VF-2. It handles mild steel, 4140, and stainless without issue. The 12,000 RPM top speed just means you also get excellent aluminum performance.

04 How fast are the rotary axes on the UMC-750SS?

The B-axis tilts at 170 degrees per second and the C-axis rotates at 179 degrees per second. These are more than three times faster than the standard UMC-750's 50 degrees per second, which makes a significant difference in cycle time on parts requiring frequent axis repositioning.

05 Is the UMC-750SS worth the premium over the standard UMC-750?

If your shop runs primarily aluminum 5-axis parts or has multi-tool programs with frequent tool changes, the SS pays for itself in cycle time savings. The 40% faster tool changes and 33% faster rapids add up on every part. For steel-dominant shops running fewer tool changes, the standard UMC-750 may be the better value.
