We started it. We're still doing it. Nobody does it better.
TSI invented the turret sleeving process — and after 35+ years and over 150,000 installations across 22 countries, we're still the standard everyone else tries to copy. We are the first and original company to sleeve Amada turrets. We install USA-made hardened steel sleeves to restore your turret back to OEM tolerances.
Others have come along claiming to offer the same service. But there's a difference between copying a process and mastering it. Our engineers have more hands-on turret restoration experience than anyone in the industry. When your machine's accuracy is on the line, you want the company that wrote the book, not the ones still reading it.
A proven 4-step restoration developed over 35 years and refined across 150,000+ installations.
Every station is thoroughly cleaned and inspected. We measure each bore to identify which stations are out of tolerance and document the wear pattern before any work begins.
Using our state-of-the-art portable boring equipment, we bore out each worn station to a precise oversized diameter — perfectly centered and perpendicular to the turret face.
All bored stations are thoroughly cleaned and inspected again before sleeve installation. No chips, burrs, or contamination are tolerated at this stage.
USA-made hardened steel sleeves are installed into each bored station with a precision interference fit. Each sleeve is aligned to Amada OEM tolerance.
Turret Sleeving International restores OEM tolerances to the upper turret stations on the Amada Turret Punch Press with our proven turret restoration process. TSI's turret refurbishing experts will install hardened steel sleeves in the upper turret of your Amada punch press, which will restore the OEM specifications.
TSI has been solving turret accuracy problems for the past 35+ years. We specialize in repairs for the Amada style turret punch press, including:
Any and All Amada Punch Presses
Vipros, EM, EML, EMK, EMZ, AE, Coma, Pega, Vela, Apelio, Aries, and any King or Queen models.
Every punch stroke puts stress on the upper turret station bores. Over time — thousands or millions of hits later — those bores wear out of round. The result is punch misalignment, poor hole quality, broken tooling, and scrapped parts.
Replacing an entire Amada turret punch press can cost $100,000–$500,000+. TSI's sleeving process restores the machine to factory spec for a fraction of that — and gets you back in production in just 2–3 days.
Every sleeve is manufactured in the United States and will never be outsourced. You get consistent quality, every time.
Our sleeves restore bores to exact Amada factory specifications — not "close enough." Your tooling fits perfectly, just like new.
Our field engineers come to your facility. Most complete turret restorations are done in just 2–3 days with no machine shipping required.
After initial installation, your own personnel can replace Retro Sleeves if ever needed — no special tools or TSI visit required.
We invented this process in 1990. Over 150,000 sleeves installed worldwide means we've seen every problem and solved it.
TSI field engineers serve customers in 22 countries including every US state plus Canada, Mexico, Asia, Africa, Australia, the Middle East, and Europe.
Comprehensive repair and refurbishment for all Amada turret punch press models.
We install hardened USA-made steel sleeves that restore OEM bore tolerances to upper turret stations — the process we invented in 1990.

Learn More →Modernize your aging Amada control system with an advanced FANUC-based control systems replacement. Breathe new life into older machines — upgrade the brain without replacing the whole press.
Learn More →Full machine refurbishment including X/Y ball screws, LM guide rails, clutch & brake, work holder clamps, and PC control replacement.
Learn More →Quality guide keys, auto-index guides, bottom die holders, upper lifter springs, collars, and die holders for all Amada models.
Learn More →Don't scrap a perfectly good Amada just because the control is obsolete. TSI replaces aging CNC controllers with advanced FANUC-based control systems that extend machine life by decades.

Real photos from real jobs — before, during, and after turret restoration across the USA and worldwide.
Family-owned and operated since 1990. Our field engineers have restored turrets on every continent — and they bring that experience directly to your facility.
When Turret Restoration Company was founded in 1990, we developed the original sleeving method for the Amada turret punch press. One of our original founders, Steve Durfee, is still actively involved in service and development today.
TSI has a broad customer base spanning every US state, Canada, Mexico, Asia, Africa, Australia, the Middle East, and most of Europe. All sleeves are made in the USA and will never be outsourced.
