Broken Tool Detectors

Home  News  Products  Contents  Contact us  Company Information

Middex-Electronics GmbH is the inventor of probe-type tool monitors. In 1978 the WK1T was introduced to the metalworking industry. The WK4T followed shortly. In 1992 the WK1 replaced both systems, offering better control, up to date electronics, and a much smaller controller size. In 1994 the TCS1 and in 1996 the BKS1 single and two tool monitor was introduced. Utilizing their vast experience in motor drive systems Middex launched in 2000 the most advanced single tool monitor WK2 featuring a speed and torque controlled drive and a patented shavings deflector seal. The WK3 opens a new dimension of mechanical tool monitoring. Increased resolution accuracy in the sensor and advancements in the controller allows a very accurate measuring of the part position or tool tip. The latest addition is the WK5 which was designed to handle especially small diameter tools (from 0.1mm and up).
 
Besides an engineer's headache, a broken tool in automatic machining produces bad parts, upsets customers, and jeopardizes tools further down the line. Protect your profits by taking charge of production and parts quality by employing broken tool monitors on screw, transfer, milling, lathe, CNC and secondary machines. Monitor tools such as drills, taps and reamers. If one should break, the machine or the automatic machining cycle will stop immediately.
