Schematic Diagram & Dimensional Reference Nomenclature
Use the standard industrial descriptions below to reference parameters mapped in the component drawing:
- D (Gauge Diameter): Mapped to the maximum outer diameter profile parameter cross-section of the taper body at the defined gauge boundary line.
- A (Point Length): Represents the operational geometric projection extending outward from the taper’s gauge boundary to the vertex point.
- C (Body Length): Details the entire insertion profile depth dimension of the solid Morse Taper shank body.
- L (Overall Length): Reflects the exact global engineering end-to-end master length calculation value (Formula: L = A + C).
- Angle (θ – Theta): Indicates the global standard 60-degree precision ground workpiece mating center point geometry angle.
