Used MICRON Grinding Machines for Sale

About MICRON Machines

MICRON MACHINERY CO., LTD. is a Japanese manufacturer based in Yamagata. Its machine-tool business is concentrated on centerless grinding machines, internal grinding machines, and the automation required to integrate these processes into production lines.

The company offers centerless grinders for both through-feed and in-feed work. Depending on the model and configuration, these machines can process straight cylindrical parts, stepped components, pins, shafts, bearing parts, threads, and eccentric workpieces. Its range includes compact cantilever machines, rigid double-supported wheelhead designs, inclined-bed models, and systems equipped with automatic loading or setup functions.

MICRON’s MIG internal grinders focus on accurate machining of small bores, seats, end faces, and related internal features. Available configurations include single- or multiple-spindle arrangements, shoe-type work support, high-frequency grinding spindles, and separate axis control for specialized bore-grinding cycles.

Typical applications include automotive injectors, nozzle needles, valves, plungers, balance shafts, motor shafts, bearings, medical components, and construction-equipment parts. The company also documents grinding experience with titanium, Inconel, ceramics, carbon, glass, resins, and other challenging materials.

Used MICRON machines attract buyers that require repeatable roundness, cylindricity, dimensional control, and production-oriented automation. Their value on the secondary market depends heavily on the exact grinding configuration, wheelhead condition, control generation, installed handling equipment, and availability of application-specific tooling.
