What it is
How it works
General reference — not yet source-verifiedA lapping and polishing machine typically holds the workpiece against a rotating plate or similar contact surface while slurry or abrasive media and applied load drive controlled material removal.
Where it fits in the process flow
General reference — not yet source-verifiedCMP and lapping tools sit in surface-preparation and planarization steps where controlled removal is needed before later inspection, bonding, coating, or assembly operations.
The PR Hoffman 6 DG Lapper belongs to the class of equipment used when a process requires flatness improvement, surface refinement, or removal of excess material from a precision part.
Applications
General reference — not yet source-verifiedCMP-class lapping and polishing equipment is used for precision substrates, wafers, and other parts that require controlled removal and smooth, flat surfaces.
