Lapping Plates

Checked Lapping Plate

Cross-hatch and checked patterns for controlled break-in, slurry retention, and uniform plate conditioning.

Overview

Checked and cross-hatch geometries help distribute slurry evenly during break-in and steady-state lapping. The pattern supports plate conditioning cycles and reduces localized loading on soft materials.

Plates are matched to our machine platforms and process recipes for repeatable flatness and surface integrity.

Typical use cases

  • Break-in and plateau finishing on seal faces
  • Ceramic and hard-metal coupons before production runs
  • Processes needing strong slurry retention on the lap
