# Richwood Industries > Richwood Industries has built and stood behind centrifugal barrel finishing (high-energy deburring and surface finishing) machines since 1988. Based in Gardena, Los Angeles, California. Unlike build-to-order competitors, Richwood keeps every size in stock in Los Angeles and ships in about one week, publishes Richwood-direct pricing on the website, and puts the owner's cell phone on every quote. Serves the United States, Canada, and Mexico. ## One-liner Richwood is the centrifugal barrel finishing company that ships in a week instead of 90 days, for the small-to-mid shop that needs to clear a bottleneck now. The reason to believe: a warehouse full of machines in LA and the owner's cell phone on every quote. ## Key facts - In business since 1988 (roughly 37 years building and backing these machines). - Category: Centrifugal barrel finishing machines (also called high-energy finishing or centrifugal barrel tumbling), mass finishing equipment, deburring machines. - Differentiators: In stock in Los Angeles, about 1-week shipping (vs ~90 days for build-to-order competitors), Richwood-direct pricing published on the website, owner-direct support, and the ability to watch the exact machine run on video or send a sample part to be finished in the actual unit before purchase. - Is the machine good? A true gear-drive system (not a chain or belt) drives steady power to every barrel with fewer wear parts and simple maintenance. High-grade bearings and quality components hold finish quality run after run. - Location: 13215 Halldale Ave, Gardena, CA 90249, USA. - Phone: 310.970.0084. Email: sales@richwoodindustries.com. - Sister company: Deburring Shop (deburringshop.com), a full-service finishing job shop in Gardena, CA that runs Richwood equipment and stocks finishing media and compounds. For customers who want parts finished rather than buying a machine. - Full product reference catalog: catalog.richwoodindustries.com covers every Richwood machine family (controlled velocity, high-energy, centrifugal disc, vibratory, spin dryers, wheel finishing), all media types (ceramic, plastic, porcelain, steel, nuggets), all numbered compounds, and the plastic media equivalent chart that cross-references 62 competitor grades across 10 brands to Richwood RP media. - Note: Some specifications, prices, and unit counts on the site are illustrative placeholders pending final confirmation. Unknown specs are shown as "on request", never invented. ## Machines (smallest to largest) - RW-6 (formerly HE-6): XS / benchtop high-energy machine. 4 barrels, 1 liter. Prove the process on your own parts before scaling.

Separator unit add-on: $10,000 added to any machine at the time of order, or $12,999 purchased on its own. ## How centrifugal barrel finishing works Parts, media, water, and compound are loaded into barrels mounted on a rotating turret (the "Ferris-wheel" principle). The turret spins while barrels counter-rotate, generating centrifugal force up to ~25 G that presses media against parts. This deburrs and polishes in minutes what vibratory finishing (~1 G) takes 4 to 24 hours to do, and produces an isotropic finish (uniform in every direction, no directional tool marks) that improves fatigue life and consistency. Full guide: /how-it-works ## Centrifugal vs vibratory - Centrifugal barrel: highest energy (up to ~25 G), cycle of minutes to ~1 hour, best for isotropic/mirror finishes and fastest deburring on small-to-medium parts. Richwood's focus. - Vibratory tub/bowl: low energy (~1 G), cycle of 4 to 24 hours, best for very large or long parts and gentle bulk finishing. - A batch that takes a vibratory bowl 4 to 8 hours often finishes in about 30 minutes in a centrifugal barrel, up to roughly 16 times faster. Honest comparison: /centrifugal-vs-vibratory ## Industries served Firearms and defense (barrels, bolts, carriers, rails, casings; the anchor vertical), aerospace, medical device, dental, space/satellite and additive/3D-printing post-processing, and contract manufacturing. ## Key pages - Home: https://www.richwoodindustries.com/ - Machines index: https://www.richwoodindustries.com/machines - Pricing: https://www.richwoodindustries.com/pricing - In stock / live inventory: https://www.richwoodindustries.com/in-stock - How it works: https://www.richwoodindustries.com/how-it-works - Centrifugal vs vibratory: https://www.richwoodindustries.com/centrifugal-vs-vibratory - Why Richwood (since 1988): https://www.richwoodindustries.com/why-richwood - Send us a part (free sample test): https://www.richwoodindustries.com/sample-test - Media & compounds: https://www.richwoodindustries.com/media - Industries: https://www.richwoodindustries.com/industries - Testimonials: https://www.richwoodindustries.com/testimonials - Blog & case studies: https://www.richwoodindustries.com/blog - Contact / get a quote: https://www.richwoodindustries.com/contact - Full product reference catalog (machine families, media grades, compounds, equivalent chart): https://catalog.richwoodindustries.com ## Common questions - How fast can I get a machine? A stocked size ships in about one week from Los Angeles, versus ~90 days for build-to-order OEMs or 8 to 10 weeks plus ocean transit for overseas-direct. - Is pricing published? Yes. Richwood-direct starting prices are on each machine page and on /pricing. - How long has Richwood been in business? Since 1988. - Is the machine actually good? Yes. A true gear-drive build (not a chain or belt), high-grade bearings, and quality components hold the finish run after run. - Can I see it before buying? Yes. Watch the exact unit run on a video call, or send a sample part to be finished in the actual machine. - Who do I talk to for support? The owner directly. There is no call center or rep layer. - What if I just need parts finished, not a machine? Use the sister company, Deburring Shop (deburringshop.com).
