Double-sided lapping for parallelism and flatness

Double Sided Lapping and Polishing Metal Parts

Planetary double sided lapping is the process of choice for achieving best flatness, thickness and parallelism on all types of metal parts. Valley provides both double side and single side lapping of metals including Stainless Steel, Aluminum, Copper, Titanium, alloys and others.

The process is stress free without thermal distortion and is suitable for ferrous and non-ferrous materials.

Typical double-sided lapping applications include:

  • Precision piston rings
  • Precision spacers
  • Gage slacks
  • Seals
  • Computer components
  • Engine components
  • Pump components

Quality control and measuring instrument calibration to ISO 9001:2008 standards.

Achievable specifications by double-sided lapping for parallelism and flatness:

  • Flatness: to 1/10 wave (0.0000023")
  • Parallelism: to 0.000010"/inch
  • Size control: to ± 0.000020"
  • Surface finish: to Angstrom levels - depending on material.
