Form-Tool Confi guration
The form tool confi gurations have a rotating tool head with 3 tool holders, for performing up to 3
simultaneous opera tions. Tooling is available for facing, single-angle beveling, compound bevel-

self-centering mandrel.
Single-Point Confi guration
The single-point machine is provided with a tool slide that feeds the tool radially across the face of
the pipe or fl ange. The slide is driven by a starwheel that engages trips on a ring mounted to the
machine housing. Bevels are performed using the Speed Prep auto-feed system, which automati-
cally feeds the machine axially as it cuts.
The single-point machine will perform facing or beveling of thick-walled pipes and fl anges.
