ISO 2768 tolerances, surface finish Ra/Rz charts, CMM measurement, and CAD/CAM optimization.
Stress-relief annealing is a sub-critical thermal heat treatment performed after heavy roughing to relax internal residual stresses and prevent long-term dimensional distortion in precision parts.
Anodizing is an electrochemical process converting aluminum surfaces into a durable, corrosion-resistant aluminum oxide layer with controllable dimensional build-up and hardness up to 65 HRC.
Electroless Nickel Plating (ENP) is an autocatalytic chemical reduction process that deposits a completely uniform nickel-phosphorus alloy coating across all internal bores, blind holes, and threads.
Flatness defines a form tolerance where a surface must lie between two parallel planes without datum reference; Parallelism is an orientation tolerance constraining a surface equidistant to a primary datum plane.
Abrasive bead blasting propels fine spherical glass beads or angular aluminum oxide media at high velocity to remove CNC machining tool marks, eliminate light burrs, and deliver a uniform non-directional matte finish.
A CMM is a 3D metrology system utilizing high-precision touch-trigger, scanning, or optical sensor probes to measure geometrical characteristics with sub-micron volumetric precision.
True Position in Geometric Dimensioning and Tolerancing (GD&T) defines a 2D circular or 3D cylindrical tolerance zone within which the center axis or center point of a feature is permitted to vary.
ISO 2768 defines general tolerances for linear dimensions, angular dimensions, and geometrical features that do not have individual tolerance annotations on engineering drawings.
Surface roughness (Ra and Rz) quantifies microscopic deviations on machined surfaces, directly influencing friction, seal integrity, fatigue life, and cosmetic appearance.
