Overview
The Hurco DCX3226HT 5Si is the most capable machine in Hurco's double-column lineup, combining the wide-envelope DCX3226 platform with a trunnion-mounted rotary table for full simultaneous 5-axis machining. This is a machine that exists because some parts simply cannot be made in three axes regardless of how many setups you're willing to do. Impellers, turbine blades, complex mold cavities with steep draft angles, and aerospace structural components with compound contours all demand simultaneous 5-axis movement, and the DCX3226HT 5Si delivers it on a scale that most 5-axis machines cannot match.
The linear travels are generous: 3,200 mm (126 in) in X, 2,600 mm (102.4 in) in Y, and 920 mm (36.2 in) in Z. The integrated trunnion table adds A-axis rotation of +30 to -120 degrees and full 360-degree C-axis rotation, providing simultaneous 5-axis interpolation across the entire working envelope. The trunnion table itself accepts workpieces up to 1,500 mm (59 in) diameter, while the fixed table areas on either side of the trunnion can hold fixtures and workholding for 3-axis operations.
The spindle is upgraded on the HT variant: a high-torque CAT 50 unit delivering 37 kW (50 HP) continuous power at up to 8,000 RPM. The additional power and speed over the standard DCX models are essential for 5-axis work where tool engagement angles and cutting forces change continuously throughout complex toolpaths. The 8,000 RPM ceiling also provides acceptable finishing performance in aluminum, though dedicated high-speed 5-axis machines will outperform it in pure aluminum applications.
Programming 5-axis parts on the WinMax control is where Hurco genuinely differentiates this machine from competitors. WinMax's 5-axis Transform Plane feature allows conversational programming of angled features and compound surfaces that would otherwise require CAM software. While the most complex simultaneous 5-axis toolpaths still require CAM, Hurco's control handles 3+2 positioning and simpler 5-axis contouring operations directly at the machine. For complex simultaneous work, WinMax accepts output from all major CAM systems.
The DCX3226HT 5Si weighs approximately 38,000 kg (83,776 lb) and requires a substantial foundation designed to support the additional dynamic loads generated by the trunnion table's rotary motion. The 40-tool ATC handles CAT 50 tooling, and the tool magazine is positioned for efficient tool changes across the machine's operating envelope.
New DCX3226HT 5Si machines represent a significant investment at $600,000-$800,000. The combination of large-envelope double-column construction with true 5-axis capability puts this machine in a relatively exclusive category. Used availability is extremely limited. Comparable machines from other builders include the Parpas Diamond and Jobs LinX, both at substantially higher price points.

Strengths & Limitations
Strengths
- True simultaneous 5-axis capability on a large double-column platform — a rare combination that handles complex parts other 5-axis machines simply cannot fit
- WinMax 5-axis Transform Plane enables conversational programming of angled and compound features, reducing dependence on CAM software for 3+2 positioning work
- 37 kW high-torque spindle at 8,000 RPM provides the power and speed required for demanding 5-axis cutting operations in steel and titanium
- 3,200 x 2,600 mm linear travel envelope accommodates large workpieces that exceed the capacity of standard trunnion-style 5-axis VMCs
- Double-column bridge construction maintains rigidity across the full working envelope, critical for consistent accuracy in 5-axis contouring operations
- Combination of fixed table areas and trunnion allows mixed 3-axis and 5-axis work on the same machine without reconfiguration
Limitations
- 4,000 kg trunnion table capacity is substantially less than the fixed-table DCX3226i's 10,000 kg, limiting the weight of parts that can be 5-axis machined
- 40-tool magazine is constraining for complex 5-axis programs that may require extensive tool libraries for contouring, finishing, and deburring operations
- 8,000 RPM spindle speed falls short of dedicated 5-axis aerospace machines (15,000-24,000 RPM) for high-speed aluminum finishing
- Extremely high entry price of $600,000+ before installation costs limits this machine to shops with consistent large 5-axis work to justify the investment
- Complex 5-axis machine requires skilled operators and programmers — the WinMax control helps, but simultaneous 5-axis work still demands experienced personnel

Frequently Asked Questions
01
New DCX3226HT 5Si machines typically price between $600,000 and $800,000 depending on trunnion table configuration, probing systems, and software options. Total installed cost including foundation, rigging, and electrical work can approach $900,000. Used availability is extremely limited due to the specialized nature of this machine. Comparable used large 5-axis double-column machines from any manufacturer typically trade in the $350,000-$550,000 range.
02
The DCX3226HT 5Si adds a trunnion-mounted rotary table providing A-axis and C-axis rotation for simultaneous 5-axis machining. The spindle is upgraded to 37 kW at 8,000 RPM (vs. 30 kW at 6,000 RPM). The trunnion table load capacity is 4,000 kg versus the fixed table's 10,000 kg. The fixed-table areas remain available for 3-axis work. Linear travels are identical. Choose the 5Si when your work requires 5-axis access that cannot be achieved through multi-setup 3-axis approaches.
03
The trunnion is integrated into the machine's table structure and is not designed for removal. However, when doing 3-axis work, you can simply lock the A and C axes and use the trunnion table surface as a fixed platform, or fixture parts on the surrounding fixed table areas. Many shops use the machine in mixed mode, running 3-axis jobs on the fixed table areas while reserving the trunnion for 5-axis work.
04
The WinMax control accepts standard G-code from all major CAM systems. For simultaneous 5-axis work, shops commonly use Mastercam, NX, CATIA, hyperMILL, or PowerMill with Hurco-specific post processors. Hurco provides post processor support and works with major CAM vendors to ensure compatibility. For 3+2 positioning work, WinMax's conversational programming can handle many operations without CAM software.
05
The DMG Mori DMU 210 P is a more refined 5-axis platform with higher spindle speeds (typically 12,000-18,000 RPM), faster dynamics, and a more sophisticated pallet system. However, it also costs $1.5M+ and has a smaller working envelope. The DCX3226HT 5Si offers substantially more X-travel and a lower price point. For heavy cutting in steel and titanium, the Hurco is competitive. For high-speed aluminum aerospace work, the DMG Mori has clear advantages.
06
Hurco offers 5-axis specific training at their Indianapolis facility or on-site. The WinMax control's 3+2 positioning is relatively intuitive for operators familiar with 3-axis conversational programming. Full simultaneous 5-axis work requires both CAM expertise and understanding of tool orientation, collision avoidance, and machine kinematics. Budget for 1-2 weeks of operator training and concurrent CAM training for your programmers.
