CNC Machining of Stepped Shafts & Pins: On CNC
High-precision batch turning of stepped shafts, custom pins, and guide pins. Precise machining of multiple step diameters, groove forming, and fine surface finishing.
Manufacturing Technology & Engineering Solutions:
Manufacturing stepped shafts and guide pins requires high geometric precision, strict concentricity between step diameters, and excellent surface finish. Production of this batch is performed on modern CNC lathes, enabling high-accuracy machining in a single clamping setup.
- MULTI-STEP TURNING & CONCENTRICITY Precision turning of multiple mounting diameters within tight tolerances. Single-setup machining guarantees zero runout and high concentricity across all steps.
- GROOVE FORMING & CHAMFERING Machining dedicated retention grooves for circlips, seal rings, and thread relief, along with precise edge chamfering.
- CENTERING & GUIDING FEATURES Machining precision center holes or tapered/spherical tips at shaft ends for smooth alignment and fast assembly into mechanisms.
- FINE SURFACE FINISHING & GEOMETRY CONTROL Achieving superior surface quality straight off the lathe without secondary grinding, utilizing optimized cutting parameters and premium carbide tooling.
