12X8 HI-ACCURACY CENTERLESS GRINDER
12x8
Hi-Accuracy Infeed
Sub-micron diameter control. 8″ wide wheel. Built for demanding tolerances.
When tolerances tighten and parts are longer, the 12×8 Hi-Accuracy is the machine the application calls for. Sub-micron diameter control, a Starrett granite surface plate bed, and four work wheel dressing options make this the system accurate and personal for very demading applications.

THE STORY BEHIND THE PART
Every part we grind at the show has a story behind it. The 12×8 Hi-Accuracy Infeed is grinding a Ford F350 6.7L Powerstroke fuel injector — a part that passed through three Royal Master hands before landing on this machine. Ground to micron-level tolerances across multiple diameters. Watch the full story behind the part.
THE SOLUTION FOR YOUR CHALLENGE
THE 8" WIDE WHEEL OPENS YOUR OPTIONS
IN A SINGLE GRIND PASS
Bar Grinding
Ideal machine for bar grinding from .020″ up to 1.5″ – all materials up to 16 feet. Automatic bar loaders are available.
You want to grind multiples across the wheel face.
The 8″ width supports multi-part infeed setups with CNC dressing on one or both wheels, significantly increasing throughput without adding machines.
You need automation flexibility.
From simple operator assist to full robotic cells, this machine supports the full range. The 24″ three-panel touchscreen keeps complex setups manageable.

WHAT SETS IT APART
THE HIGHLIGHTS
9 Nanometer Glass Scale — 1/4 Micron Diameter Compensations
Sub-micron positioning is standard. The glass scale closes the loop on diameter control at levels other machines can’t reach.
8" Wide Grinding Wheel — Straddle Bearing Design
The width enables multi-part infeed grinding in a single cycle. Straddle bearing design adds rigidity for heavy, consistent cuts.
8" Thick Starrett Granite Surface Plate — Lapped to .0002" Flatness
The machine base is a precision reference surface. Thermal stability and flatness are built into the foundation, not added on.
Four Grinding Wheel Dressing Options
Standard template, automatic template, single-point CNC, and rotary disk CNC dressing. Match the dress profile to the application.
24" Three-Panel Touchscreen Control
All process data, compensation controls, and machine status in one interface. Built for operators running complex, high-volume applications.
Automation from Operator Assist to Full Robotic Cells
The platform is designed to scale. Add automation at the level the application requires, today or in the future.
Post-Process Gauging Integration
Gauge feedback closes the compensation loop automatically. Pair with data collection for 24-hour production environments.
