Precision & Performance for motor-driven spindles

CYSPEED motor spindles by CYTEC are built from a modular kit and cover almost the entire spectrum of milling, drilling and grinding tasks:

• Power: from 13 kW to 115 kW rated power (S1), with S6 ratings of up to 138 kW for intermittent duty.
• Torque: rated torque from 20 Nm for high-speed machining up to 700 Nm (S1) – and up to 1,200 Nm with planetary gear option (i = 3) on the CSG series.
• Speed: maximum speeds of up to 24,000 rpm, depending on the series and bearing concept.
• Tool interfaces: HSK-A63, HSK-A100, SK50 and C8 – matched to your tooling standard.
• Milling head compatibility: every spindle can be checked against the CYMILL head series (NANO, P, S, S-HD, M-HD, G, G-HD, T and K) directly in the selector.

• Modular spindle kit: asynchronous or synchronous motors, different lengths, bearings and interfaces are combined into a CYSPEED motor spindle configured specifically for your application – standard performance data with custom fit.
• Honest S1/S6 ratings: CYTEC specifies both continuous (S1) and intermittent (S6) performance, so you can design your process around realistic values instead of peak marketing numbers.
• Proven in demanding industries: CYTEC motor spindles run in tool and mold making, automotive, aviation and aerospace applications worldwide – often integrated in CYMILL milling heads for 5-axis milling and turning.
• Made in Germany, serviced in the USA: engineering and manufacturing in Jülich, Germany; service, spare parts and the CYTEC Spindle Hotel available through CYTEC Systems Corp. in Cape Coral, Florida.

Start with the basic filters for minimum power, torque, speed and tool interface. For a concrete machining task, use the peak filters: enter the spindle speed your process requires and the torque it must deliver at that speed – the selector calculates the available torque along each spindle's characteristic curve (full torque up to the base speed n_base, then decreasing with rpm) and shows only spindles that truly meet your operating point. Add candidates to the compare list, review them side by side, and export a PDF datasheet of your favorite including the performance chart.

• What is the difference between S1 and S6 ratings? S1 is the continuous duty rating a spindle can deliver permanently; S6 is an intermittent duty rating with higher short-term power and torque. Use S1 for roughing over long cycles, S6 for processes with load breaks.
• Can CYTEC customize a spindle for my machine? Yes. The CYSPEED modular kit allows customer-specific configurations – motor type, interface, length, sensors and cooling are adapted to your application.
• Which spindle fits my CYMILL milling head? Activate “Select by milling head” in the selector and choose your head series – only mechanically compatible spindles remain selectable.
