Spindle主轴
A spindle is the rotating assembly in a machine tool that holds and drives the cutting tool or workpiece, delivering torque, speed control, and often drawbar or coolant functions. In manufacturing documentation it appears in CNC manuals, maintenance procedures, tooling specifications, bearing condition reports, and failure analysis, where spindle speed, taper interface, and load limits are critical technical details that must be kept distinct from auxiliary axes.

Where this term appears
In localization, spindle appears in CNC machine manuals, maintenance checklists, spare-part catalogues, vibration monitoring reports, and tooling specifications. Common phrases include “spindle warm-up cycle,” “spindle taper,” “through-spindle coolant,” and “spindle load.” Translators must use terminology that matches the machine type and the target audience, because the same word may refer to a high-speed motor spindle or a belt-driven tool spindle.
Translation checks
A common error is translating “spindle” as a generic “shaft” or “axle,” losing the machine-tool-specific meaning of a powered, tool-holding assembly. In maintenance and spare-parts documents, this can lead to ordering the wrong component or misunderstanding vibration and bearing checks. Another mistake is using one term for both milling spindles and lathe spindles without preserving the source’s distinctions, or confusing spindle speed with feed rate in operating instructions.
Keep the term aligned across your files
Check equipment names, units, safety instructions and interface labels against the source and approved references. Confirm any market-specific document requirements separately.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
