power-lathe

A worker uses a power-lathe to shape a metal cylinder.

Definition

Noun: A "power-lathe" is a machine tool used for shaping wood, metal, or other materials by rotating the workpiece against a cutting tool, with the rotation powered by an electric motor or other mechanical power source, rather than being manually operated.

Usage Examples
  • (A machine that rotates wood for shaping.)
  • (A motor-driven lathe for metal.)
Advanced Usage

  • "to operate a power-lathe": to control and use this machine for turning materials.

    • She learned to operate a power-lathe during her apprenticeship. (She became skilled at using the machine.)

  • "power-lathe cutting speed": the rotational speed of the workpiece, measured in revolutions per minute (RPM), which is adjusted based on material and tool type.

    • The power-lathe cutting speed for brass is higher than for steel. (The rotation rate differs by material.)
Variants and Related Words

  • Lathe (n): a machine for shaping material, which can be manual or powered.

    • He used a simple hand-cranked lathe before upgrading to a power-lathe. (A basic lathe without motor.)

Additional Notes
  • The hyphen in "power-lathe" indicates that it is a compound word combining "power" (mechanical energy) and "lathe" (a shaping machine). The hyphen may be omitted in informal writing, but it is standard in technical contexts to clarify the meaning.
