Capability decision data

Technical fit for CNC plastic turning

Use this capability summary to decide whether the process fits the part before discussing tooling, lead time or price.

Best fit: Round plastic parts, bushings, rollers and concentric features produced efficiently from rod or tube stock.
Design focus: Workholding, slenderness, internal bores, wall stiffness, tool pressure and thermal expansion affect concentricity.
Material direction: Stock-shape stability, residual stress, moisture and softness change speeds, feeds and achievable finish.
Volume and cost logic: Bar size, setup, cycle, material yield and secondary milling or drilling determine part cost.
Inspection focus: Inspect diameters, runout, concentricity, length, thread fit, burrs and surface condition.
Compare against: Compare turning with milling for prismatic geometry and molding when repeat volume justifies tooling.
