ciency of the 360° magnetic flux available. The non-contact, iron-free design provides smooth, friction-free motion without the cogging inherent in linear motor designs. The larger air gap between the shaft and forcer minimizes heat output and the effect of metallic shop dust on the system. MC Machinery Systems Inc. Ph: 630-616-4068 Web site: www.mitsubishi-world.com
Swiss-Style Turning Spindles
iSPeed3 series Swiss-style turning machine spindles have a reputation for reliability and durability in machining environ-
ments like medical and aerospace applications. The compact iSpeed3 series have sensorless motors and diameters of 19.05 to 25 mm and can machine from 1000 to 80,000 rpm. Based on work envelope requirement, spindles can have ei- ther right angle wiring or they can now be supplied with wiring that exits directly out of the back of the unit. Designed to uti- lize up to a 4-mm collet (standard 1/8" collet), the air-cooled motor can meet a variety of machining requirements with the ability to be supplied in over 15 different varieties, including self-contained flange mounts.

Tool Monitoring Adaptive Control Tool Monitoring Adap- tive Control (TMAC) is a system developed by Caron Engineering Inc. that learns the tools’ cutting horsepower used in the machining process. By monitoring power levels, TMAC can pinpoint breakage and wear while the tool is in its cutting cycle. The adaptive control feature automatically
adjusts feedrates according to variations in cutting conditions like hard/soft spots, more/less material etc. Corrective actions such as feed hold, cycle interrupt, tool retract, and other ac- tions can be taken to the machine from unnecessary down- time and costly repair.
