Rottler H85AXY CNC Automatic Vertical Honing Machine with Hole-to-Hole Automation & Optional Block Roll Over

The Rottler H85AXY is one of the most advanced CNC-controlled vertical honing machines available, designed for shops that demand the highest level of automation, precision, and flexibility. Building on the capabilities of the H85AX, the H85AXY adds a fully programmable Y-axis movement, allowing the honing head to automatically position itself in both X and Y directions for multi-cylinder layouts — including offset bore engines, industrial cylinders, and large diesel blocks.

 

The optional Block Roll Over System transforms the machine into a full-featured automated honing workstation. By rotating and indexing the block under CNC control, shops can hone multiple angles or surfaces without manually repositioning the workpiece, dramatically improving throughput, accuracy, and operator ergonomics.

 

With servo-driven stroking, automatic size control, built-in geometry correction, and Rottler’s sophisticated CNC touchscreen interface, the H85AXY delivers unmatched cylinder geometry, surface finish consistency, and production efficiency.

 

This machine is ideal for high-performance engine builders, diesel and industrial rebuilders, and production facilities needing a fully automated honing platform.

Key Features

  • CNC-Controlled X & Y Axis Positioning: Allows the honing head to automatically move between cylinders in both directions — essential for modern engines with staggered or offset bores.
  • Hole-to-Hole Automatic Indexing: Complete multi-bore honing cycles run automatically with minimal operator involvement, dramatically increasing productivity.
  • Optional CNC Block Roll Over System: Lets the machine rotate and reposition the block for access to different cylinder banks or angles, enhancing automation and reducing manual handling.
  • Automatic Bore Geometry Correction: Corrects taper, out-of-round, barrel shape, and distortion with real-time servo adjustments during the honing cycle.
  • High-Torque Variable-Speed Spindle: Supports diamond, vitrified, and plateau honing tools for consistent surface finish and sizing accuracy.
  • Servo-Driven Vertical Stroking System: Provides precise control of dwell location, dwell time, honing pressure, and crosshatch angle.
  • Automated Final Size Control: Machine measures and stops at the programmed final diameter, eliminating operator guesswork and ensuring repeatable sizing.
  • Advanced Rottler Touchscreen Interface: Includes built-in job memory, editable programs, honing strategies, crosshatch control, and production-tracking capability.
  • Industrial-Grade, Rigid Construction: Cast-iron column and heavy steel base minimize vibration and maintain accuracy even with long-stroke honing on large diesel blocks.
  • Ideal for High-Volume, Multi-Cylinder Production: Perfect for diesel service shops, industrial engine rebuilders, heavy equipment repair, and performance machine shops.

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.
