The new Rottler H85A

Rottler H85A CNC Diamond Hone honing a Subaru block

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

Standard Equipment

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.

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.
