Used Okamoto Surface Grinders for Sale 6

Okamoto is the global volume leader in surface grinding, and its ACC series, from the toolroom ACC-63 class to large automatic ACC-DX machines, sets the de facto standard for saddle-type flat grinding. Variants run manual, hydraulic, and fully programmable with automatic downfeed and dressing.

Used Okamoto grinders are the default choice when shops add flat grinding capacity. Exapro listings vary by table size (typically 450 × 150 mm up to 600 × 2,000 mm classes), automation, and condition. Compare specifications and submit an enquiry through the listing page on Exapro for seller details.

Surface grinders earn their keep over decades, which makes the used market the rational place to buy one, and Okamoto the rational default brand: the company has shipped more surface grinders than any rival, so parts, knowledge, and comparison machines are everywhere. The ACC naming encodes table capacity (an ACC-64 grinds roughly 600 × 400 mm), with suffixes marking the control level: ST and DX manual and hydraulic machines for toolrooms, CA and iQ versions adding programmable downfeed, auto-dressing compensation, and cycle automation for production grinding.

Against used Jones & Shipman or ELB machines, Okamoto typically trades at similar or slightly lower prices with broader parts availability; against new Taiwanese grinders, a clean used Okamoto often costs less and grinds flatter. The decisive variable is condition rather than age, because a 25-year-old grinder that lived in a temperature-stable toolroom can outperform a younger machine from production duty.

Buying a used Okamoto surface grinders: what to check

Spindle condition dominates value: listen at full speed for bearing noise, check for visible runout at the wheel flange, and ask about spindle rebuild history. Test the table drive through full strokes at varied speeds; hydraulic machines should reverse smoothly without shudder. Inspect the table and saddle ways for scraping wear and verify the lubrication system reaches all points.

Grind a test part if at all possible and measure flatness and surface finish, the only proof that matters. Check the magnetic chuck for grinding wear and uniform holding, confirm the dresser mechanism operates, and on automatic machines verify downfeed increments execute accurately. Review coolant tank and filtration condition, often neglected on used grinders. Check the spindle for thermal stability by running it for twenty minutes before measuring, and inspect the table ways and wheel head for grinding grit ingress.

On Exapro, used Okamoto listings show table size, control level, photos, and location. Compare available machines and submit an enquiry through the listing page on Exapro to request test-grind results and inspection access.
