Specifications include, but are not limited to: Machining Capacity: 6in–72in (153 to 1829mm) pipe, large diameter vessels. Cutter Drive: Pneumatic: 4 hp governed air motor coupled with worm gearbox. Hydraulic: As above, with hydraulic motor. Cutter Speed: Pneumatic: Adjustable from 35–55 rpm for use on work-hardened alloys. Hydraulic: Adjustable from 0–60 rpm. Feed: Pneumatic: 3/4 hp air motor coupled through overload clutch, gearbox and chain reduction to final machine drive sprocket. Hydraulic: 4 hp hydraulic motor. Feed Method: Positive, nonslip chain drive. Air Requirements: 100 cfm @ 90 psi (.05 m3/s @ 6.21 bar) Hydraulic Requirements: 13–15 gpm @ 1500 psi (49.2–56.78 lpm @ 103.42 bar) not to exceed 2000 psi (137.9 bar) Work Speed: 3in (76.2mm) surface feed/min maximum, or appr. 1 min/in (1 min/25.4mm) of pipe diameter. 10in (254mm) pipe = 10 min.
