Lapmaster 16" Lapping Polishing Grinding Plate Disk Flat Crown 1.2 2.0 Lot 13
This is a lot of 13 Lapmaster 16-inch lapping and polishing plates, offered as a mixed variety lot. The lot includes both flat and crowned plate profiles in several grades and types, as labeled on the individual pieces — including 1.2 Crown, 2.0 Crown, and HI 2.0 Crown configurations, along with plain flat plates. Grade and series codes stamped or labeled on the rim edges include CLX26, CLX30, and ISL11, among others. All plates feature a large center bore and metal rim construction typical of precision lapping machine plate assemblies.

Applications
Lapmaster lapping plates are precision consumables used in flat lapping and polishing machines for producing extremely flat, smooth surface finishes on metal, ceramic, glass, and semiconductor workpieces. The flat plate profile is used for standard flat lapping operations, while crown plates (such as the 1.2 and 2.0 crown configurations in this lot) impart a controlled convex or concave geometry to workpieces — a technique commonly used in optics fabrication, bearing seat finishing, and precision mechanical component production. Lapmaster machines and their associated plates have long been standard equipment in aerospace, optical, semiconductor, and precision machined-parts manufacturing. A lot of mixed plate types and grades like this is useful for shops running a Lapmaster 16" machine that need spare or replacement plates across different finishing stages, or for facilities transitioning between surface profiles without sourcing plates individually.
This lot of 13 Lapmaster 16-inch lapping and polishing plates has been pulled from a working environment and inspected. The plates include a mix of flat and crown profiles (1.2 Crown, 2.0 Crown, HI 2.0 Crown) along with plain flat types, with various grade/code markings visible on the rims (CLX26, CLX30, ISL11, and others). Condition varies across the lot: several plates show significant surface rust, oxidation, and lapping compound buildup on the rim and abrasive faces, while others have cleaner surfaces with only light residue and normal wear consistent with prior lapping use. The abrasive faces and center bores are intact across the pieces photographed. This is a lot sale — all 13 plates are included as shown. Please view our photo set and contact us if you have any questions.
