MODERN MACHINE SHOP 99 BETTER PRODUCTION Surface Grinding Japan, so the lead time was less than six weeks," Mr. Marsilius says. Moore Tool moved quickly to prepare its facility for the new machine. The shop renovated a room for it, installing air condi- tioning to keep the room's temperature to a con- stant 68°F, and poured a special deep foundation with rebar to isolate the machine from nearby production area vibrations. The ACC3280CHiQ is a double-column-type surface grinder with a cast iron base and 30-horsepower spindle. According to Okamoto, this is nearly three times the power as conven- tional double-column surface grinders. Moore Tool wanted the new machine to have a table size and travels that were similar to the old machine. The ACC3280CHiQ's table measures 30 by 80 inches and the distance from grinding wheel to top of table is 23.5 inches. "We grind a lot of parts that consume most of the table size," Mr. Marsilius says. That said, because the company also grinds much smaller parts, having large table capacity offers the f lexibility to run a variety of part sizes. That, however, is where the similarities between the two machines end. Moore Tool's ACC3280CHiQ surface grinder has standard features and options that have enabled it to increase grinding quality, efficiency and speed. These include: Conversational control. Okamoto's iQ touchscreen control was a major selling point for Moore Tool. It can be programmed conversationally, offer- ing an intuitive interface for machine operators who use it to set up parts and write their own programs at the machine. In fact, operators were writing programs and running jobs after only a couple days of training from Okamoto. It also stores programs, which is useful for repeat jobs. Mr. Marsilius says that the old surface grinder's control had been retrofitted at some point, but its software was very basic. "The conversational control was a huge step up," he says. Coolant-delivery system. Moore Tool also pur- chased a Grind Bix coolant aeration system from Okamoto, which produces ultra-fine bubbles to enable the coolant to get into the grinding wheel and part to assist part cooling and reduce wheel wear and part surface warpage.
