The SAPORITI Threading & Rotor Milling family (PLUS CD, PLUS 400, SAR 500) delivers heavy-duty, multi-axis milling and threading solutions for screws and rotors. Designed for demanding industries, such as pumps, compressors and extrusion applications, this range combines rigid, electro-welded machine beds with high-torque spindles, advanced anti-chatter systems and flexible tooling options (disc cutters, HSK/ISO spindles, adjustable holders) to machine complex profiles with repeatable accuracy. All models use Siemens CNC controls, support modern probing and tool-changer options, and are Industry-4.0 ready, providing a reliable, production-oriented platform for both roughing and precision finishing across a wide span of diameters and lengths.
Thread milling for medium-duty screw production
The SAPORITI PLUS 400 is a versatile thread-milling machine for screws and rotors, combining multi-axis motion with a slanted bed for excellent ergonomics and chip control. Designed for threads, splines and hobbing operations, the PLUS 400 supports both conventional and advanced cutter systems and comes ready for integrated process probing and automated tool handling.

Disc-cutter milling for complex screw profiles
The SAPORITI PLUS CD is engineered for high-precision milling of screw profiles that require disc cutters, for example multi-lobe or cam-type co-rotating screws, pumps and compressor rotors. Its 45° inclined bed and closed, windowed safety enclosures give operators a clear view of the process while the machine’s patented anti-chatter system reduces spindle vibration and noise to deliver superior surface finish and longer tool life.

Heavy-duty milling for pump & compressor rotors
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.
