Bel Air Finishing Supply Inc. (North Kingston, RI) centrifugal disc finishers help manufacturers increase throughput, decrease cost, and increase part quality by polishing and deburring a wide range of materials including aluminum, brass, copper, kovar, stainless steel, steel, and titanium. In addition to eliminating 80% of the handwork involved in manual deburring operations, they drastically reduce surface roughness (Ra) of parts for the aerospace, automotive, medical, and other industries.
Sizes range from 4 liters to 60 liters and most models come with a mobile frame, ideal for cellular and just-in-time production. Options include integrated ultrasonic cleaners, on-board media storage, a direct compound feed system, and parts separation.
How it works: The bowl-shaped finishing chamber consists of a fixed upper bowl and spinning bottom disc. The disc rotates both the media and parts within the chamber, forcing the mass to the stationary outside wall. The mass of part(s) and media then folds back to the center. This process is repeated, creating a 3-D, toroidal action similar to a vibratory bowl finisher but with 10 times the g-force.
While this is happening, water and finishing compounds are added into the mix to keep the media and parts clean. Effluent containing the broken-down parts of media, small amounts of part materials, and water mixed with compounds flow through the gap, wearing it down. Unlike more traditional disc finishers, the adjustable gap system on Bel-Air’s machine extends service life by allowing the gap to be closed as it wears.
Manufacturing Industry Invited to Take Reshoring Survey
AMT and the Reshoring Initiative will use the survey results to identify which processes, products and components face the most pressure from imports and which offer the biggest opportunities to reshore. Part of AMT’s “Rebuilding the Supply Chain” initiative, the survey is open to OEMs, job shops, technology suppliers and distributors through the end of February.
Year-Over-Year November U.S. Manufacturing Technology Orders Up 1.4%
While November’s $330.3 million represent a decrease of 13.3% from October, AMT’s president says it’s clear ‘the sector did not fare as poorly as originally predicted.’
