F103A – Traveling Column Boring, Surfacing & Line Boring Machine

Rottler F103A Traveling Column Boring, Surfacing & Line Boring Machine

General Details

The F103A is designed for machining smaller engine blocks used in ‘On Highway’ applications such as trucks and buses. At the same time it is a large machine capable of machining mid range size blocks up to the size of a CAT 3508 and 3412, Komatsu 170 V12, MTU 2000 V16, Cummins K38, Detroit 60, Mercedes 400 V12, etc.

All F100A machines employ an entire array of features which help maximize the productivity capabilities of the machines. Quick tooling changeover maximizes the versatility and flexibility of the machine, allowing boring and surfacing in one setup. All F100A Series machines have the capability of Boring, Surfacing, Line Boring, and Universal Machining. Traveling column and spindle movements operated by precision ball screws and AC servo motors. Optional Automatic cycle software and production tooling allow complete block banks to be machined without operator attendance, once the job is set up and the “cycle start” button is pressed, the operator is free to “walk away” and do other work while the F100A completes a block bank or main line bore unattended!

  • Versatility – Change cutterheads from surfacing to boring and back in 15 seconds.
  • Heavy Duty – Rottler rugged machine tool quality for accurate and long life. Heat treated mehanite cast iron castings.
  • Large Diameter Spindle – All F100A machines incorporate the use of a large diameter hard chromed spindle, utilizing high precision angular contact bearings and automatic lubrication.
  • Machine ways are induction hardened and coated with turcite low friction material and supplied with air pressure to reduce friction and give long service life.
  • Anti-friction Ball Screws and AC Servo motors provide precise machine positioning and rapid feed rates.
  • Air power draw bar allows cutterheads to be changed in second, increasing productivity and reducing operator fatigue. The machine can be changed from boring to surfacing in less than 15 seconds.
  • Automated workhead tilting system for surfacing provides “back clearance” for superior surface finish.
  • Increased clearance from spindle to centerline to the machine’s column allow large castings to be set up and machined.


Conversational programming system easy to learn and operate. The use of Windows style icons and graphical displays makes programs easier to understand, the old fashioned abstract G&M code programming has been replaced with easy to understand conversational icons and menus. The use of Windows information allows easy handling – everyone knows about file saving and copying to external laptops and desktop computers. Programs can be emailed worldwide via the Internet and transferred by simple USB flash memory drives.

Rottler CAD/CAM (Computer Aided Design and Manufacturing) – While the operator is developing a program on the machine, laptop or desktop, the software is calculating things like tool paths in the background. The software is able to convert a drawing into a complex CNC program and run the machine with very little operator involvement.
