Overview

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!

Features

• Productivity - Up to 75% time savings over traditional machines
  
• Control - Touch Screen Controls located on one panel for ease of operation
  
• Automation - Automatically machines precise dimensions
  
• Flexibility - Block boring and surfacing, head surfacing, line boring and general CNC machining. 
  
• 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 EM100 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. Linear Roller type guideways in X- axis provide smooth and precise movement under heavy loads. 
  
• 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.

Control

Rottler has combined our own in house CNC programming and machining experience with software and programming
experts to develop a new conversational programming system that is 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 PATH CAD/CAM Software (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.

ConRod Fixture

Connecting Rod Fixture- Rottler’s patented Connecting Rod Fixtures allow large connecting rods to be surfaced and bored on the EM103H machines. The Rottler boring fixtures allow both big end and small end to be bored in one set up resulting in perfect  parallelism between big end and small end. All the rods in a set can be  accurately bored for equal center to center distance, a must for today’s high compression diesel engines. Special heavy duty fixtures available for boring  very large, heavy connecting rods found in natural gas compressors and  workboat marine engines are available.
