The SAPORITI SAR 500 is a CNC machine for the fast manufacturing of pump and compressor screws by Disc Cutters with surprising features. 

This machine has 5 CNC-controlled axes: two linear, one rotary and two spindles. 

The SAPORITI SAR 500 can easily machines workpieces up to 500 mm in diameter with cutters diameters up to Ø 440 mm. 

Maximum workable length: 1200 mm. 

The milling head tilting axis reach ± 50°. 

The machine is equipped with CNC Siemens 840D SL and motors with forced liquid cooling to reduce power composition and machine noise level. 

The linear axes run on precision roller bearings. The positioning accuracy is guaranteed also by the use of linear encoders.

The chattering noise, which is typical of working with disc cutters, is cut down in this machine thanks a special device patented by SAPORITI Company.

It is possible work without problems also extremely hard steels such as 17-4-PH (with extremely high hardness HRC 34-HB300) with pass depth even of 80 mm.

It can be use cutters with coated tips and also disc cutters in solid carbide steels or brazed.

The machines rigidity allows for high chip removal and very good surface finishing. 

To cover a wide range of working diameters this machine can be equipped by two hydraulic rests with long blades easily interchangeable. 

The CNC allows also the easy execution of pumps and compressors screws profiles by SAPORITI’s  especially developed customized working mask “customer friendly” to help the operator in machine using and programming.
