Rottler H87AXY

CNC Automatic Vertical Honing Machine with Hole-to-Hole Automation

Machine Operations

Cylinder Honing
Liner Honing


The H87AXY is a large capacity vertical stroke machine capable of honing large liners found in stationary and marine engines such as CAT 3600 and Wartsila 32/34 engines.


Special Version High Production Machine that can move automatically in both X and Y axis for automatic honing offset cylinder blocks and parts. This feature allows use of optional programmable roll over fixture to be able to hone a complete V block automatically – unattended! Includes feature to drain coolant out of block at end of cycle.Automatic Lower Crash Protection System Many Engine Blocks have interference in the lower area of the bores and can damage honing stones and holders. Everytime the H87X starts honing a cylinder, the machine will check bores for interference avoiding potential damage to honing stones and holders. Variances in lower bores are common. Rottler H87X Control senses lower bore interference prior torotation and stroking stroking motion starting at full power, eliminating any stone or holder damage.

Standard Equipment

Standard Equipment

Special Heavy Duty Version High Production Machine that can move automatically in both X and Y axis for automatic honing offset cylinder blocks. 

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 controls load/pressure that the honing stones exert against the cylinder wall and reduces load during finishing cycle. 

Automatic Short Stroke and Dwell - machine detects tight area and short stroke or dwells.

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 Finish Program - the machine automatically expands plateau stones/brushes to programmed load and counts down number of plateau strokes, then withdraws the stones/brushes and retracts the hone head to the clearance position.
