All Lapping Processes
Each card links to a process reference for Chicago. Use the location nav or the Service Areas section below to jump to a specific city or state landing page.
Single and Double-Sided Lapping
Planetary kinematics for flatness and parallelism across hard, brittle, dissimilar materials. CNC and bench-mounted variants.
Flat Lapping
Diamond and loose-abrasive flat lapping on cast iron and composite plates — light-band flatness, controlled Ra.
Spherical/Ball Lapping
Sphericity correction for valves, bearings, and optical balls — stationary fixture, arm-type, and centerless variants.
Hand Lapping
Operator-finished prototype and low-volume work tuned to geometry and inspection criteria.
Machine Lapping
Planetary, single-side, and CNC platforms for repeatable lot-to-lot finish and flatness.
Mechanical Seal/Silicon Wafer Lapping
Carbon, ceramic, SiC seal faces and Si/SiC wafer substrates lapped to sub-micron flatness.
Production Lapping
Long-run contract lapping with documented process cards and per-lot certification.
Taper, Shoulder, and Counter Bore Lapping
Custom mandrels for internal tapers, shoulders, and counter bores in hardened steel and carbide.
