The SGF80 Seat and Guide Machine is designed for Heavy Duty Diesel , Propane , and Locomotive Cylinder Heads.The SG80 also has extended capacity height for large work pieces. The Windows XP operating system
stores data such as  pilot size, cutter part numbers, job tittles and all of the cutting parameters.Feed rates  for both the rough and finish cycles, RPM's
and vertical Zero locations are all controlled by the PC.
Rottler’s new patent pending UNIPILOT TOOLING system allows the carbide centralizing UNIPILOT to work like a live pilot – stays in the spindle while moving from valve guide to guide – but at the same time has a fixed pilot design to give improved CONCEN.

Fixed (dead) pilots have proven over the years to give more accurate CONCEN compared to live pilots mainly because live pilots have clearance between the pilot and the guide.
