Overview
The Hurco BX 400i is a trunnion-style 5-axis machining center that brings simultaneous 5-axis capability to job shops and production facilities looking to consolidate multi-setup work into a single machine. Built around a tilting rotary table (A+C axis trunnion), the BX 400i provides full 5-axis simultaneous interpolation with Hurco's WinMax control, enabling complex aerospace, medical, and automotive components to be completed in one setup.
The machine's 12,000 RPM, 30 hp CAT 40 spindle provides the power and speed range needed for a wide material palette, from titanium and Inconel to aluminum and engineering plastics. The trunnion configuration accommodates parts up to 400 mm in diameter with the table in the horizontal position, and the integrated A-axis swivel (typically ±120 degrees) and full 360-degree C-axis rotation provide complete access to all five faces and complex compound angles.
Hurco's WinMax 5-axis control includes tool center point management (TCPM) and automatic workpiece probing integration, reducing the setup expertise required to run 5-axis work profitably. For shops that have previously avoided 5-axis due to programming complexity, the WinMax conversational environment provides a meaningful accessibility advantage over machines running only G-code-based controls.
The BX 400i is targeted at mid-size job shops and contract manufacturers transitioning from 3-axis operations to 5-axis capability. Its combination of a capable trunnion design, accessible control, and Hurco's established service network makes it a practical entry point into production 5-axis work without the capital outlay of a dedicated aerospace-grade 5-axis platform.

Strengths & Limitations
Strengths
- Trunnion design provides full 5-face access for complex aerospace and medical parts
- WinMax 5-axis control with TCPM reduces programming complexity for job shops
- Consolidates multi-setup work into single operations, improving part accuracy
- 40-tool ATC supports the tool variety required for complex 5-axis programs
Limitations
- 400 mm max workpiece diameter limits use on larger aerospace structural components
- CAT 40 taper is less optimal than HSK-A63 for high-frequency 5-axis finishing passes
- Higher price point relative to 3+2 indexed 5-axis machines without simultaneous capability

Frequently Asked Questions
01
Yes. The BX 400i and WinMax control support both 3+2 positional (indexed) 5-axis and full simultaneous 5-axis interpolation. Many shops run 3+2 positioning for the majority of their work and use simultaneous mode for impellers, turbine blades, and other truly complex geometries.
02
Maximum workpiece height on the BX 400i is dependent on the trunnion position. In the standard horizontal (A=0) position, clearance is approximately 400 mm above the table surface. When programming compound angles, users should verify clearance in the CAM simulation before cutting.
03
Yes. The BX 400i's 30 hp spindle and rigid trunnion structure support titanium machining at production depths of cut. Through-spindle coolant (available as an option) is strongly recommended for titanium to manage heat and extend tool life.
