Rottler H85AX CNC Automatic Vertical Honing Machine with Hole-to-Hole Automation

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.

Key Features

  • Hole-to-Hole CNC Automation: The machine automatically positions the honing head from one cylinder to the next, enabling multi-bore honing cycles without operator assistance.
  • Fully CNC-Controlled Honing Cycles: Programmable stroking, load control, dwell, spindle speed, and sizing operations run automatically for consistent results every time.
  • Automatic Bore Geometry Correction: Corrects taper, barrel, out-of-round, and other distortions using servo-controlled compensation routines during the honing cycle.
  • Large Block Capacity: Suitable for gas and diesel engine blocks, sleeved engines, industrial cylinders, agricultural engines, and high-performance builds.
  • Precision Servo Stroking System: Ensures extremely uniform crosshatch angles, consistent dwell distribution, and fine control of surface finish quality.
  • High-Torque Variable-Speed Spindle: Designed for modern diamond tools, vitrified abrasives, and plateau-finishing heads.
  • Rottler Touchscreen CNC Interface: Simplifies job setup with preloaded honing strategies, adjustable parameters, part memory storage, and repeat-job programming.
  • Automatic Final Size Control: Machine stops exactly when the programmed bore diameter is reached, eliminating manual measuring mid-cycle.
  • Heavy-Duty, Rigid Construction: Supports long-stroke honing with minimal vibration for true, round bores even in large diesel cylinders.
  • Ideal for High-Volume or Precision Blueprinting: Perfect for shops doing multi-cylinder diesel blocks, racing engines, or production runs where precision and speed matter.

Ready to Make the Right Equipment Choice?

Built on Real Engine-Rebuilding Experience

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.
