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.

Multi-sample loading feature of the vice can accommodate up to 16 test specimens 4mm thick, all accurately cut within approximately 20 seconds increasing productivity. The quick auto-return feature ensures the vice is always in the correct place for loading and unloading the test specimens and the micro height adjustment, notch depth comparator and sample setting gauge ensure that the cut notch depth is accurately controlled. A polycarbonate guard is fitted for operator safety totally enclosing the working area and provides an electrical interlock, so the machine does not operate when the guard is open. The Dual Tooth Cutting Wheels are designed to reduce cutter load on the sample being notched. The standard cutter wheel profile fitted to the apparatus is a 0.25mm radius V notch.

Cutter wheel profiles of 0.1mm and 1.0mm radius as well as 0.8mm and 2.00mm ‘U’ notch wheels are also available. Non-standard and special notch requirements can also be provided for.
