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 (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 saporiti company has been constructing machinery tools since 1946 and in those early years manufacture included horizontal and vertical lathes and milling machines. with the automation explosion in the early 70's, saporiti went beyond traditional machinery to include and eventually specialize in computer numeric control end user application machinery which was specifically tailored to meet the customers requirements and thus after many inquiries started to manufacture machinery to satisfy the plastics sector.....with today's complex designs of single and twin screws it was necessary keep these machines as user friendly as possible as to avoid complex and time consuming tool setups and concentrate on a more dedicated and flexible control system.
