We Rebuild and Renew
Semitool Robots



Years of Semitool experience


ClassOne Equipment has many years of experience in refurbishing Semitool lift-rotates and robots, turning them into better-than-new, high-performance equipment subsystems.


Our refurbishment process addresses and corrects common modes of failure such as vibration or shaking, intermittent signal failure, and loss of motion. Every unit is completely disassembled and each subcomponent is inspected for physical damage before being cleaned. All critical and high-failure parts are replaced with NEW components of equal or better quality.


Upon reassembly, we perform a thorough series of tests to ensure proper performance and operational reliability. Our 72-hour qualification process eclipses a wide range of checkpoints from wafer handling to signal continuity.


Please contact a ClassOne Equipment representative to inquire about expedited refurbishment services for "tool-down" emergencies.
