    Automatic Lower Crash Protection System
    Many Engine Blocks have interference in the lower area of the bores and can damage honing stones and holders. Every
    time the H85A 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 H85A Control senses lower bore interference prior to
    rotation and stroking stroking motion starting at full power, eliminating any stone or holder damage.
    • 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.
