Benefits & Technical Highlights
The SAR 500 is a heavy-duty threading and milling machine tailored to pump and compressor rotor manufacture. Built around a robust electro-welded structure with large roller guideways, the SAR 500 handles larger diameters and demanding materials while its patented anti-chatter solution ensures stable cutting and superior surface quality even under interrupted disc-cutter cutting conditions.
Benefits
Built specifically for pump and compressor rotors and high-precision screw profiles
High cutting torque and power for demanding materials and deep passes (example: 17-4-PH with 38 HRC or 360 HB)
Patented anti-vibration system reduces noise and improves surface finish and tool life
Heavy structural design and large roller guideways for lasting accuracy and minimal vibration
Full enclosures and Industry 4.0 connectivity for safe, modern production environments
