CNC Turning and Milling Center
NTM-308S
X:730 / Y:250(±125) / Z1:1,200, Z2:1,250 (mm)
NTM-308S combines turning and milling capabilities in one machine, integrating a C-axis turning spindle with a B-axis swiveling milling spindle to support multi-face and process-integrated machining. The B-axis swiveling range of -30° to 210° provides greater flexibility for angled machining, while the C-axis supports 360° rotation for turning and milling operations. By reducing multiple setups and process transfers, NTM-308S helps improve machining flexibility, accuracy, and overall productivity.
• B-axis milling spindle tilting range: -30° to 210°
• C-axis A2-6/8” chuck turning spindle
• HSK-63T 32-station chain-type tool magazine
Feature
Turning and Milling Integration:
Combines turning and milling operations in a single setup, minimizing multiple clampings and transfer between machines.
Sub-Spindle Machining:
Equip sub-spindle available to support front and rear machining of workpieces and smooth part transfer between the main and sub-spindles.
Compact Built-In Motor Milling Spindle:
Increases the machinable working range and reduces interference zones.
Orthogonal Structure:
Facilitates vertical chip evacuation and provides an optimized machining space configuration.
High-Rigidity Support Design:
Shortens the distance between the spindle centerline and the Z-axis guideways, helping to minimize structural deflection caused by cutting torque.
Structural Topology and Cutting Stability Analysis:
Utilized to optimize machine structure and dynamic performance.
