Rottler H85A CNC Touch Screen 2300 lbs
The H85A has an 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 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. 
Vertical Stroking System
CNC Servo Controlled High Pitch Ball Screw and Hardened Steel Linear Slideway
Systems allow precision vertical stroking and fully automated operation, creating a
true constant cross hatch pattern thoughout the entire length of the bore increasing oil
retention while reducing oil consumption extending engine life and reliability. 
Monitored Variable Load Control
A must for cylinder honing! ‘Load’ is used to describe the pressure
that the honing stones experience against the cylinder wall during
the honing operation. Roughing cycles require higher loads for faster
stock removal and finishing cycles requires lower loads to reduce
distortion. The H85 is programmed with roughing and finishing
loads automatically controlling the stone pressure while honing
cylinder bores producing the desired geometry and surface finish
in every cylinder. Honing time is substantially reduced for maximum
productivity and repeatability.
