Okamoto has set the global benchmark for precision grinding since 1926. From hand-feed surface models to full CNC cylindrical and profile grinders, every machine is built on a rigid, vibration-damping casting and finished to sub-micron tolerances. TechMach now brings that legacy to manufacturers across Arkansas and the St. Louis metro.

Surface & Profile Grinders with iQ Touchscreen Control

Okamoto’s ACC-, CH-, and SA-Series surface grinders combine heavy Meehanite® frames with exclusive iQ Touch Screen Control, letting operators set wheel dress, plunge depth, and spark-out in a few taps while the machine auto-optimizes parameters for finish and stock-removal rate.

Cylindrical & Internal Grinding in a Single Setup

OGM-NCIII cylindrical grinders use a T-shaped main casting, double-V slideways, and Fanuc touchscreen CNC to grind up to ten diameters—OD, shoulder, and face—in one automated cycle.

Automation Ready – From Robot Loaders to Auto Data Creation

Optional loaders, gauging, and the CH-iQ series’ auto-data-creation software cut change-over time and let shops run lights-out on everything from mold bases to aerospace actuators.

Local Expertise, Statewide Service

Whether you’re polishing carbide dies in Little Rock or finishing turbine shafts in Fort Smith, TechMach installs, calibrates, and services every Okamoto grinder with factory-trained technicians and OEM spare parts.

What kinds of grinders does Okamoto manufacture?
Okamoto builds manual, automatic, and CNC surface grinders; ID/OD cylindrical grinders; rotary (vertical-spindle) grinders; and custom profile machines up to double-column formats for extra-large workpieces.
How accurate are Okamoto surface grinders?
Thanks to hand-scraped slideways, precision ballscrews, and hydrostatic spindle bearings, most models hold flatness within ±0.000050 in. and surface finishes down to 2 µ-in. Ra.
What is the iQ Touch Screen Control?
The iQ interface replaces manual dial inputs with a color touchscreen that auto-calculates wheel dressing, feeds, and spark-out passes—reducing setup time and extending wheel life.
Can Okamoto grinders run lights-out?
Yes. Robots, pallet loaders, and in-process gauging allow unattended production; the CH-iQ series can even generate optimal grinding parameters automatically for new parts.
Does TechMach provide training and maintenance?
Absolutely—our factory-certified team offers on-site operator training, preventive-maintenance programs, and emergency repair across Arkansas and the St. Louis region.
