The Rottler H85AX is an advanced CNC vertical honing machine engineered for shops that demand maximum automation, precision, and production efficiency. Built on the proven H85A platform but enhanced with automatic hole-to-hole indexing, the H85AX allows complete multi-cylinder honing cycles to run with virtually no operator intervention.
This machine is ideal for diesel rebuilders, high-performance engine builders, and production facilities needing consistent geometric accuracy across multiple bores — including straightness, roundness, taper control, and plateau finishing.
With servo-driven stroking, fully programmable dwell logic, automatic sizing, and Rottler’s intuitive touchscreen CNC interface, the H85AX delivers world-class cylinder geometry and repeatable results. It is designed for high-volume, multi-cylinder jobs where automation dramatically reduces labor time and improves throughput.

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.
