Hermle G 500

The Hermle G 500 is a 5-axis gantry machining center designed for large-format workpieces that exceed the capacity of Hermle C-series trunnion-table platforms. Unlike the C-series, which achieves 5-axis motion by tilting the workpiece, the G 500 keeps the workpiece stationary on a fixed table and delivers A/B-axis articulation through a swiveling milling head on a gantry structure. This approach accommodates extremely heavy and large workpieces without load-transfer complications.

The G 500 provides X/Y/Z travels of 2,000 mm x 1,500 mm x 1,000 mm with a fixed table rated for 5,000 kg. Applications include large aerospace structural panels, automotive body-die mold bases, energy sector housings, and large defense structures. The articulating head delivers plus or minus 120 degrees of A-axis swivel and continuous C-axis rotation for full 5-axis simultaneous interpolation across the entire working volume.

Hermle uses the same mineral-cast base technology on the G 500 as across the C-series, providing exceptional vibration damping and superior surface finish quality at large scale. The gantry structure is thermally compensated to maintain positional accuracy across extended production runs. Standard spindle is 18,000 rpm HSK-A63; a 24,000 rpm option suits high-speed aluminum applications.

Automation on the G 500 typically uses linear transfer systems and dedicated fixturing rather than the pallet-handling systems on C-series machines. The Heidenhain TNC 640 or Siemens 840D sl control provides the same programming environment as the rest of the Hermle lineup, reducing cross-training requirements in mixed-machine shops.
