Okamoto Grinding Machines

Surface grinders produce flat, parallel faces and precise profiles by passing the workpiece beneath a rotating abrasive wheel on a reciprocating table. Okamoto's surface and profile grinders are built for die and mold work, gauge and fixture making, and any job that demands a fine, repeatable flat finish.

Cylindrical grinders finish the outside diameter (OD) of round parts held between centers or in a chuck; universal models add internal-diameter (ID) and angle-head grinding in a single machine. Okamoto's CNC cylindrical and universal grinders pair rigid construction with multi-wheel capability for shafts, rolls, spindles, and bearing journals that must hold tight roundness and concentricity.

Internal grinders finish bores and internal diameters to high precision. Okamoto's rigid, production-oriented internal grinders suit high-volume parts such as bearing races, bushings, and hydraulic components, where bore size and surface finish are critical.

Rotary surface grinders use a rotating table beneath the wheel for high stock-removal rates and consistent finishes on high-volume flat parts. They fit production grinding of seals, washers, valve plates, and similar batch work where throughput matters as much as finish.

AEROLAP is Okamoto's dry, abrasive-airflow finishing process that polishes and deburrs complex shapes without changing part geometry. It shortens final-polishing cycle time on cutting tools, molds and dies, gears, and medical components.

Okamoto's semiconductor back grinders and polishers thin and finish silicon wafers in chip production. The back grinder uses an index table and down-feed grinding (with optional coin-stack and stress-relief equipment); the polisher's dedicated head and handling system deliver high-accuracy, high-throughput final polishing.
