The Rottler H87AXY is a high-capacity CNC vertical honing machine engineered for professional engine builders, diesel rebuilders, and industrial machining operations that require exceptional automation, precision, and throughput. As the larger companion to the H85AXY, the H87AXY offers increased bore diameter range, expanded stroke capacity, and an enlarged work envelope — making it suitable for heavy-duty diesel blocks, large industrial cylinders, and multi-bore production work.
Featuring CNC-controlled X and Y axis positioning, the H87AXY automatically indexes from hole to hole, allowing complete multi-cylinder honing cycles with virtually no operator involvement. Its advanced servo stroking, automatic geometry correction, and final-size control ensure world-class accuracy in straightness, roundness, taper reduction, and plateau finishing.
For shops that demand maximum automation and minimal handling, the H87AXY can be paired with optional block rollover systems and tooling packages for fully integrated production workflows.

Your machine’s long-term performance is our priority.
Decades before today’s engine shops trusted our equipment, Tony was already deep in the craft — rebuilding motors, machining blocks, and pushing for better precision.
A local newspaper once featured him as a standout young machinist, noting his drive, attention to detail, and obsession with doing things the right way. That same passion would eventually shape our company’s values.
Today, that commitment lives on in every machine we sell, every customer we support, and every shop we help succeed.
