SAPORITI SAR 500 is a threading machine for pump and compressor screws with surprising features. 5 CNC-controlled axes: two linear axes, one rotary axis, two spindle axes. The machine works with disc milling cutters up to 440 mm diameter. Extremely hard steels such as 17-4-PH (as well as HRC 34-HB300) can be machined with pass depth of 80 mm. Maximum workable diameter: 500 mm, max. length: 1200 mm. Milling head tilting: ± 50°. The machine is equipped with CNC Siemens 840D and motors with forced cooling. Linear axes run on precision roller bearings. The noise, which is typical of machining with disc cutters, is cut down through a special device patented by SAPORITI srl.
The machines is manufacture following the customers need and can be in different sizes up to work screws with diameters up to 350 mm and 9000 mm length. The bed can be inclined or slanted.
The disc cutter max diameter is 200 mm.
The milling head has Patented Device by Saporiti to reduce the disc cutter chattering.
Strong hydraulic rest are supporting the workpieces.
The whirling head has a bore passage of 270 mm.
The bed is a rigid structure and the carriage moves on roller guideways.
Hydraulic self centring restso hold the workpieces at the two sides of the head.
