Heavy Duty / High Horsepower Diesel CNC Machines
Extra large engine blocks weigh in excess of 20,000 lbs. (10,000 kg), so Rottler invented a completely new concept in machine tool design. The EM100 Series CNC machines are all capable of performing jobs on diesel engines. The EM107H and EM109H machines are manufactured specifically to handle the world’s biggest and heaviest engine blocks.

EM103H
Traveling Column Boring, Surfacing & Line Boring CNC Machine
Design for machining smaller engine blocks used in on-highway applications such as trucks and buses
Rotter EM103H
Horizontal travel:
80″ (2000mmm)
Target Applications:
Mid-range diesels up to CAT 3508, MTU 16V2000, and Cummins QST30
The EM103H 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 EM100 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 EM100 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 EM100 completes a block bank or main line bore unattended!

Large Diameter Spindle – All EM100 machines incorporate the use of a large diameter hard chromed spindle, utilizing high precision angular contact bearings and automatic lubrication.
Induction hardened – 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. Linear Roller type guideways in X- axis provide smooth and precise movement under heavy loads.
Precision – 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 – Clear area from spindle to centerline to the machine’s column allow large castings to be set up and machined.
