Tubeless rim re-rounders are used to re-round the welded joint on wheel rims after the trimming-planishing-side trimming operations are complete. This facilitates subsequent rim flaring and roll forming processes and helps lower the rejection rate, while simultaneously improving product quality. The tubeless rim re-rounder has a dual power hydraulic system and is comprised of the main machine, the drive mechanism, and the electric control cabinet.

• The tubeless rim re-rounder features an independent hydraulic transmission unit and electric control cabinet.
• This re-rounder uses a PLC control system and allows for 2 operating modes: manual and semi-automatic.
• Functions include over-stroke protection and over-pressure protection, emergency-stop, and filter block warning.
• The working pressure, speed and stroke can be adjusted according to specific processing needs.
