To produce precise stress concentrated notch profiles in Impact and Charpy specimens look no further than the Ray-Ran Autocycle Notching Cutter. A world leader by design, this machine will cut accurate notch profiles to international test standards such as ISO179, ISO180 and ASTM D256.  

At the heart of the machine is a custom-built adaptive Microprocessor Control Unit with LCD screen ensuring feed and cutter speeds are always selected for optimum performance. Adjustments to cutting parameters are made using the integrated membrane keypad and are stored in the memory feature of the microprocessor. Cutter speed ranges from 350 to 2500 rpm are easily controlled, and with minimum feed rates of 0.06mm/rev cutting parameters for even the toughest of materials are easily achieved.
