Remember that before there was high-tech there was low-tech. And there still is low-tech! For example, boring and cutting a keyway in a tapered bushing is one of the most often performed tasks a maintenance machinist will perform.
In connection with my article about flexible manufacturing systems for the February issue, I visited Camcraft Inc., which has a Makino Machining Complex (MMC2) automated pallet-handling system. Four Makino 4-axis a51nx horizontal machining centers are integrated into the system.
New research by the Copper Development Association Inc., McLean, Virginia, shows that U.S. machine shops may be underutilizing the machinability of brass by as much as 85 percent in part-processing operations. The study says manufacturers can and should be machining the material at significantly higher speeds and feeds—often five to 20 times faster—to increase productivity and profitability.
