Roush Yates is now partnering with Rottler and utilizing two H75A honing machines for block honing and a F69A for block machining. The H75A has been specifically developed for performance engine manufacturing. Its diamond/CBN honing system provides a seamless and reliable process. This machine is able to produce high capacity output with precision calibration. The H75A is able to hone an entire V8 block automatically, allowing the user to step away, improving overall production efficiency by 50%. The precision vertical ball screw along with new custom software allows the operator to set the cross hatch angle and machine will apply the proper stroke speed insuring the exact cross hatch angle from the top of cylinder,  to the bottom of cylinder with less than one degree variance. The H75A will also automatically correct taper in any part of the cylinder. The anti- crash protection provides another level of security and reliability in the manufacturing process.

The H70 Series machine is capable of honing in both clockwise and counter clockwise rotation. Using this reverse rotation process during the finishing of the block resulting in an overall improved bore consistency and quality.

High performance engines such as the solid billet aluminum blocks with ductile liners can precisely be honed to an exact specification and tolerance with the H70 Series. This increases horsepower while reducing blow by in one simple motion.

The two stage roughing and finishing cycle allows higher loads in the roughing cycle for stock removal and light loads for finishing helping improve productivity and accuracy. The hone head has variable speeds from 1-400 RPM for fast stock removal and a slower speed for finishing. The automatic plateau mode is designed to hold the stones at a constant pressure while counting the strokes so each cylinder is held to an exact engineered tolerance.

In addition to improved efficiencies and quality, these machines lead to a smaller overall environmental footprint, reducing downtime for routine maintenance and repair.
