STARRAG STC 800 MT VERTICAL MACHINING CENTER

Technical Description

This CNC spindle operates with 5 axes and delivers a powerful 37.3 kW output at a maximum rotational speed of 8,000 RPM, enabling high-performance machining tasks. It is equipped with an ISO 50 taper interface compatible with HSK-A100 tool holders, which offers excellent rigidity, precision, and tool retention, suitable for demanding milling and multi-axis operations. The spindle utilizes advanced CNC control for precise, programmable movements and cutting operations, ensuring accurate positioning and repeatability critical for complex geometries. Its power rating supports machining of tough materials and larger cutter diameters, balancing torque and speed efficiently for heavy-duty cutting. The 8,000 RPM speed matches typical requirements for ISO 50 taper spindles, delivering optimal performance in mid-to-high torque applications such as steel and superalloy machining. The HSK-A100 taper guarantees high concentricity and stability, reducing vibration and runout during operations. This spindle likely features robust bearing arrangements, possibly ceramic or high-precision angular contact bearings, to maintain precision under load and extend service life. Cooling is typically integrated, often air or liquid-cooled, to prevent thermal distortion during sustained high-power use. Its design supports seamless integration into CNC machining centers with automatic tool changing systems, maximizing productivity and versatility across aerospace, automotive, or mold and die manufacturing sectors requiring five-axis machining capability. Overall, this spindle combination embodies a high-power, moderate-speed drive with a precision taper, driven by CNC for advanced, multi-axis metalworking applications.
