Rottler H85A

Rottler H85A CNC Automatic Vertical Honing Machine offers true, constant and accurate crosshatch angle the entire length of the bore with machine feeding stones to specified load during honing process and withdrawing stones before stopping. Rottler understands surface finish is critical and it can be hard to replicate consistently block after block. The Rottler H85A accomplishes this with extreme reliability and can pay for itself in less than 5 years! *

• Rottler Plateau Mode loads to proper stone pressure before starting rotation and counts down number of strokes.
• Diamonds and CBN stones save money with built-in Crash Protection that prevents tearing up hone heads, stone holders and diamond/CBN abrasives.
• Modern CNC Windows based software with online capabilities.
• Save time maintaining coolant with superior filtration and roll out coolant tank.

* Pay back the cost of the machine in less than 5 years compared to traditional machines using stones and oil. Calculated considering labor saving (using Rottler CNC) and consumable savings (using diamond stones and water based coolant).

Automatic Lower Crash Protection SystemMany Engine Blocks have interference in the lower area of the bores and can damage honing stones and holders. Everytime the H85A starts honing a cylinder, the machine will check bores for interference avoiding potential damage to honingstones and holders. Variances in lower bores are common. Rottler H85A Control senses lower bore interference prior torotation and stroking stroking motion starting at full power, eliminating any stone or holder damage.

• Rottler Software is designed with Simplicity in mind. Conversational software allows operators to quickly and easily learn and create their own programs. It takes only a few minutes to create a new program for a new block then it is saved for future recall and use.

• Automatic Lower Crash Protection System – every time cycle start is activated, the machine will check that the stones will not interfere with lower bore before starting rotation and stroking preventing stone and stone holder damage.
• Spindle Taper with Quick Change System – change hone heads in seconds without any wrenches
• Automatic Honing Stone retract at End of Cycle – the machine will automatically retract the stones during last stroke so that the stones do not leave any scratches or marks in the bore.
• Automatic Cross Hatch Angle System – the machine will automatically adjust parameters to programmed cross hatch angle and finish the bore to programmed angle.
• Automatic Roughing and Finishing Load Sensing System – machine short strokes or dwells anywhere it senses a tight area.
• Electronic Hand Wheel for lowering hone head into each bore
• Automatic Stone Feed-out System – once hone head is positioned in the bore, the machine automatically expands stones and rotates slowly before starting hone cycle
• Automatic Plateau Brush Finish Program – the machine automatically expands plateau brushes to programmed load and counts down number of plateau strokes, then withdraws the brushes and retracts to the clearance position.

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.
