Wolcott ran a comparison between his current equipment and the PS95 with its 14,000-rpm, 33.5-hp (25-kW) CAT spindle. On the first run, with no changes to the program, the new machine beat the existing machine by eight minutes. The next time the part was run, feeds and speeds were increased to an optimal level for the PS95, and the part was completed 30 minutes faster. On a separate part, Wolcott achieved metal removal rates that were four times faster than those accom- plished on his previous machine. “That speed makes a real difference. For instance, the extra 30 minutes saved allows me to complete one more part per day,” said Wolcott. “On a $200 part, with the same number of employ- ees using the same floor space, time savings can produce an extra $1000 more profit per week. That kind of sav- ings quickly justifies the investment in a high-performance machine.” Besides enjoying the increased

speeds, Wolcott has experienced im- proved quality—with repeatability as tight as 0.0001" (0.003 mm) on the PS95. When doing work on the previous vertical machining centers, the company had to manually polish the parts to achieve desired finishes—doubling cycle time. On the Makino machines, parts come out in half the time as on the previous machines and require minimal hand work. ME For more information from Makino Inc., go to
