Single-sided and Double-sided Planetary Lapping and Polishing Machines
PR Hoffman’s role in the lapping and polishing industry began in Carlisle, PA in 1938, with the invention of the Hunt-Hoffman planetary lap machine by Grover C. Hunt and Philip Reynold Hoffman. The double-sided planetary lap machine revolutionized the quartz crystal industry, and the concept remains unmatched for consistent, reliable processing of parts requiring tight control of thickness, flatness, parallelism, and surface finish.
