PMK High-Frequency HSK-63 Spindles are high-performance motorized units specifically developed for modern CNC machining centers requiring high power density and extreme precision. Utilizing the industry-standard HSK-63 taper, these spindles provide superior radial stiffness and dual-contact clamping for the most demanding high-speed milling tasks.

With a power output of 29 kW and rotational speeds up to 18,000 RPM, the HSK-63 series is optimized for both aggressive material removal and fine surface finishing. The integrated tool clamping system delivers 18 kN of force, ensuring tool stability and minimal runout during heavy-duty 5-axis machining.

Key benefits

• High Power Output: delivers 29 kW of continuous power, supporting high material removal rates and shorter cycle times.
• HSK-63 Interface: ensures superior axial consistency and radial rigidity through specialized dual-contact clamping technology.
• Precision Balancing: motorized rotor assembly is precision balanced to ensure vibration-free operation at 18,000 RPM.
• Thermal Stability: optimized liquid-cooling jacket and temperature sensing maintain consistent operational geometry during long production runs.
• Reliable Performance: high-grade hybrid bearings and specialized lubrication systems provide long life and reduced maintenance.

Applications

• Advanced CNC milling, drilling, and contouring in aerospace and automotive production.
• High-precision machining of heavy die-mould components and structural alloys.
• Integration as primary high-speed heads for vertical and horizontal machining centers.
• Complex 5-axis machining requiring high torque and exceptional tool holder stability.
