Overview

The Hurco VMX42SRTi is Hurco's mid-size swivel-head rotary table 5-axis machine, designed for shops that need to put heavy parts under 5-axis toolpaths. The SRT (Swivel-head Rotary Table) configuration tilts the spindle head through the B-axis while a C-axis rotary table provides workpiece rotation. This means the part sits on a large, rigid table instead of being tilted on a trunnion — a fundamental advantage when your parts weigh hundreds of kilograms.

Travels are 1,067 x 610 x 610 mm (42 x 24 x 24 in). Note the Z-axis: 610 mm (24 in) versus 520 mm (20.5 in) on the trunnion VMX42Ui. The extra 90 mm of Z travel comes from the swivel-head design and gives you room for tall parts, long tools, and deep cavity access. The fixed table is 1,270 x 610 mm (50 x 24 in) rated for 1,360 kg (3,000 lb), with an integrated 599 mm (23.6 in) rotary table rated for 500 kg (1,100 lb).

The B-axis swivels +/-92 degrees and the C-axis rotates 360 degrees. B-axis rapid hits 50 RPM and C-axis runs at 100 RPM — significantly faster than trunnion model rotary speeds, reducing repositioning time during indexed operations.

The spindle runs 12,000 RPM through a CAT 40 / Big Plus taper, delivering 30 kW (40 hp) of peak power with 98.9 Nm (72.8 ft-lbs) of torque at 2,900 RPM. That's more horsepower than any trunnion model in the VMX42 family, matched to the machine's ability to handle bigger, heavier cuts on larger workpieces.

The 40-tool ATC carries standard tooling with 76 mm max diameter and 249 mm max length. Rapids hit 38 m/min (1,496 ipm) on X/Y and 32 m/min (1,260 ipm) on Z. At 8,400 kg (18,520 lb), this machine requires a solid foundation. Floor space is 4,954 x 3,772 mm (195 x 149 in) and power draw is 70 KVA.

New pricing runs $250,000-$330,000. The VMX42SRTi competes with the DMG MORI DMU 65 monoBlock and Mazak VARIAXIS C-600 in the mid-size swivel-head 5-axis segment.

Strengths & Limitations

Strengths

1,360 kg (3,000 lb) fixed table load handles heavy steel parts that no trunnion 5-axis in this class can support
30 kW (40 hp) spindle is the most powerful in the VMX42 family, driving face mills through steel with authority
610 mm Z-axis travel provides extra clearance for deep cavities, tall parts, and long-reach tooling
100 RPM C-axis rapid repositioning cuts cycle time by 4x compared to trunnion rotary speeds
50 x 24 inch fixed table accommodates large workpieces and multiple-part fixturing setups
WinMax conversational 5-axis programming is standard, maintaining Hurco's programming speed advantage

Limitations

70 KVA power requirement is substantial and may need dedicated electrical service in older facilities
98.9 Nm torque peak at 2,900 RPM means less low-end torque than trunnion models for interrupted cuts in steel
4,954 x 3,772 mm footprint requires significant floor space — substantially larger than trunnion variants
Swivel-head mechanism is mechanically more complex than trunnion, with higher long-term maintenance costs
249 mm max tool length is shorter than the trunnion Ui's 300 mm, limiting deep-reach tooling options

Best For

Shops machining heavy steel and cast iron parts requiring 5-axis access that exceed trunnion weight limits Aerospace manufacturers producing large structural components, frames, and brackets in aluminum and steel Die and mold shops needing 5-axis swivel-head access to deep cavities from multiple angles Energy sector manufacturers machining large valve bodies, manifolds, and turbine components Contract manufacturers handling oversized parts that need multi-sided machining in a single setup Shops transitioning from 3-axis VMCs to 5-axis that need to maintain high table load capacity

Frequently Asked Questions

01 What does a Hurco VMX42SRTi cost?

New pricing runs $250,000-$330,000 depending on options. Through-spindle coolant, probing, chip conveyor, and coolant chiller are recommended additions. Used machines from 2016-2021 sell for $140,000-$220,000 depending on hours, condition, and options.

02 Should I get the SRTi or the trunnion Ui?

If your parts weigh more than 250 kg with fixturing, or are too large for a 15.7-inch trunnion table, the SRTi is the clear choice. If your parts are smaller and lighter, the trunnion Ui provides better indexing accuracy and costs $70-90K less. The SRTi also has 90 mm more Z travel for deep-reach work.

03 How does the swivel head affect accuracy compared to trunnion?

Both configurations achieve similar accuracy specs (±5 arc-second positioning). The key difference is workpiece orientation — on a trunnion, the part tilts with the table, which can affect coolant delivery and chip evacuation on steep-angle cuts. The SRT keeps the part flat while the spindle tilts, generally providing better chip management.

04 Can I use the fixed table area outside the rotary table?

Yes. The 1,270 x 610 mm fixed table can be used as a standard 3-axis work surface with 1,360 kg capacity. You can fixture parts on the flat table area surrounding the rotary, or remove the rotary table entirely for large 3-axis work. This dual-purpose capability makes the SRTi versatile.

05 What's the B-axis maintenance schedule?

The swivel-head B-axis is the most mechanically complex component. Hurco recommends annual inspection of the clamping mechanism, lubrication system checks every 1,000 hours, and periodic backlash verification. Plan on $2,000-$5,000 per year in B-axis-specific maintenance costs above what a trunnion machine requires.
