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.

The Rottler S80A machines combine cutting edge control technology with proven traveling column machine tool dry surfacing technology to give the world's most advanced surfacing machines available today. The S86A is designed for surfacing from the smallest to large heavy duty diesel heads and blocks.

The Rottler SG8 machine does many cylinder head machining operations such as multi-angle valve seat cutting, boring out valve seat inserts/rings and boring housings for oversize valve seats, reaming valve guides and boring/reaming for oversize valve guides, cam follower boring, spring seat and valve guide machining, drilling and thread tapping, removing broken bolts and thread repairs, as well as many other operations.

The VR10 set new standards in speed and accuracy for performance racing and remanufacturing cylinder head work. The air operated ball precision chuck system eliminates collets. Valve face is machined concentric to the valve stem for improved sealing, better heat transfer and reduces mechanical stresses on valves. Robins VR10 precision chuck is manufactured from the highest grade Bohler Tool Steel and hardened by Bohler for the highest grade hardened tool steel available in the world today making it a prime machining unit in every machine shop.
