PR Hoffman
The PR Hoffman 32T is an insert carrier and lapping carrier model. The PR Hoffman 32T is designated 32T. The PR Hoffman 32T is intended for double-sided planetary lapping and polishing machines and double-sided planetary lapping machines.[1][2][3]
A lapping carrier is a workholding plate used in double-sided planetary finishing equipment. A carrier keeps parts separated in shaped openings while the machine moves the carrier between opposed plates with abrasive slurry or polishing media. An insert carrier uses removable inserts or workhole arrangements to suit the part geometry being processed.
Double-sided planetary lapping and polishing systems use carriers to transmit motion from the machine drive into a planetary path across the finishing plates. The carrier constrains each workpiece while exposing both faces to simultaneous processing. Carrier design influences part spacing, edge support, media access, and wear behavior during the run.
Lapping carriers belong in abrasive finishing flow where flatness, parallelism, thickness control, or surface preparation is required before later cleaning, inspection, polishing, bonding, or assembly. Double-sided planetary processing is typically used after slicing or rough stock preparation and before final surface qualification.
Carriers of this class are used to process flat parts that benefit from controlled double-sided abrasion or polishing. Typical uses include wafers, disks, seals, optics, ceramics, metals, and other precision components that must be held in repeatable pockets during surface generation or finishing.

Carrier geometry and material affect how the part is supported, how evenly it moves through the abrasive field, and how well it resists chipping, distortion, or uneven removal. For delicate or high-precision parts, carrier selection is a major process variable.
Typical parts include thin disks, wafers, optical components, ceramic pieces, and other flat parts that require controlled thickness, parallelism, and surface refinement during abrasive finishing.
