.jpg) July 7, 2008 - Advanced Machine & Engineering, (AME) Rockford, IL, announces the OTT/JAKOB Position Monitoring System with the Electronic Analog Sensor, which allows users to monitor machine tool power drawbars for performance and wear. An electronic analog sensor detects the position and an electronic unit attached to the machine controller transmits the data. This system indicates whether tools are clamped, unclamped or not present. It can increase tool head accuracy and longevity by monitoring cycles and hours, indicating whether your tools are properly held. Because these units transmit information quickly to the onboard machine controls, mechanical signal rings with inductive sensors are now obsolete. Negative influences of the signal rings at higher RPM can therefore be avoided. Components of the Monitoring System Include: The OTT/JAKOB unclamp unit contains a cylindrical, inductive analog sensor consisting of a primary and secondary coil. During clamping or unclamping, as the drawbar connection moves axially through the analog sensor, the target ring on the drawbar connection triggers the output signal. The signal increases as the target ring further enters the sensor, indicating the position. The position is also monitored during the milling process. The sensor electronics supply the primary coil with constant frequency and amplitude. A demodulator transforms the signal of the secondary coil into a stable DC output signal. The position-controller evaluates the current signal and sets the output signals at the adjustable limits. A digital filter compensates existing peak values. The position-controller is equipped with a meter to display operating hours and operating cycles. Advanced Machine & Engineering Co., located in Rockford, Ill., is a global manufacturer and distributor of precision machine components, fluid power components, fixturing/workholding, power drawbar and spindle interface components, and saw machines and blades. The company also designs and builds special machines for a variety of industries and provides machine rebuilding, retrofitting and contract manufacturing services. AME has partners and customers around the world and across the U.S. |
