We at Rottler have been designing and manufacturing machines since 1923 and we used those 89 years of experience to produce a new class of machine intended for both the small to medium size diesel engine rebuilder and the performance racing engine builder.  These versatile machines are able to perform common jobs such as boring/sleeving, surfacing (heads and blocks), main and camshaft line boring, and general industrial CNC machining with Rottler CAM software.Our latest CAD Software (featured in the EM79 and several of our other models) allows our tools to incorporate many functions and roles in one multi-purpose machining center, providing the diversity of many different machines in one  package.The EM70 Series completes the range of Rottler Machinery that exists today.

Control

Rottler Exclusive Touch Screen Programming
The conveniently located control pendent centralizes the machine controls. Only the buttons and interactive menus required for a particular machine operation are displayed. Machine operations can easily be done manually or automatically, with the ability to store programs in memory. Digital readout allows the operator to accurately monitor position at all times. Control operates in metric and inch systems.

Fully Programmable Cycles
Conversational 3 axis CNC control, PC based with Windows Operating System.

Dimensions and Control through Touch Screen:

• Program Bore Centers, Exact Depth, Speed, Feed, etc.
  
• Machines complete bank or main line in Automatic Cycle.
  
• Lower Offset Boring allows lower sleeve repair in Automatic Cycle.
  
• Circular Interpolate Counterbores for Radius Undercut or Wide Counterbores.
  
• Surfacing/Milling – Multiple Pass – program for Rough Cut and Finish Cut for superior surface finish.
  
• Line Boring – program the bearing bores and length of each bore and the machine automatically moves from bore to bore, completing the line unattended.
  
• Face Main Line Thrust Faces square to centerline of Crankshaft using Rottler Circular Interpolation software.
