All components are used with Finite Element Methods ( FEM ), which provides advantages of an optimal design and a light-weighted structure, to ensure overall mechanical rigidity. The center-symmetric spindle head reduces thermal distortion while ensuring structural stability and machining accuracy. The direct-drive spindle provides 45 N-m max. torque output which can fulfill high speed machining requirements ( SIEMENS ). The BT30 spindle provides low energy consumption and outstanding surface roughness advantages. The axial drive system is driven by a direct-drive motor which provides optimal indexing precision and fast indexing capabilitiy. Large size chip groove with circular coolant nozzle provides optimal chip removal.
