Okamoto’s ACC-3280CHiQ double-column surface grinder is designed for high-precision grinding of large components, particularly demanding mold and die base production applications. According to the company, the machine’s double-column design and robust construction stand up to prolonged, heavy-duty grinding conditions, while a double-V table way construction promotes accuracy.
A “reform” mechanism automatically adjusts for crossrail slide wear without CNC compensation, helping to maintain a high degree of flatness across the workpiece surface. Other notable features include a Shift-Plunge grinding cycle for fast, efficient stock removal and multi-level grinding capability to enhance flexibility.
The machine comes standard with a 30-hp spindle motor and 20" diameter concave grinding wheel. Table size is 32" × 80". Maximum pass width is 40". The maximum distance under standard wheel is 23.5". Table load capacity (including chuck) is 5,512 lbs. Larger-capacity models are also available.
All data input can be completed using only two data screens with Okamoto’s iQ software.
Other features include a grinding wheel adapter; a hydraulic wheel dresser with dress compensation; a dresser stand with diamond tool; an automatic oil temperature regulator; a spindle speed controller; and more.
The BIX high-pressure coolant system is available as an option. This system optimizes grinding throughput with a tenfold increase in vertical infeed amounts, the company says. The BIX System also minimizes wheel clogging, extending wheel life. Other options include electromagnetic chucks, a 24" grinding wheel, dynamic balancing apparatus and more.
