Product Description
The Auto Cycle Notching Cutter. has been designed to machine a very precise stress concentration notch in test specimens to ensure that breakage of the specimen takes place at the same section each time a test is carried out. Mainly intended for use with plastic polymer materials, the variable speed range of the cutter and traverse feed enables the optimum cutting conditions to be established for each different material

The apparatus is capable of producing notch profiles to all International test standards, such as ASTM D256, ISO 179 and 180. The cutters are made from tungsten carbide which is an extremely hard and durable material. The cutting edges are optically profile ground to very close tolerances. Different cutter profiles are available to suit standard and special notch requirements.

The Dual Tooth Cutting Wheels are made from tungsten carbide with cutting edges that optically ground to very close tolerances. The standard wheel fitted to the apparatus is the 0.25mm radius cutter. However 0.1mm and 1.0mm radius, and 0.8mm and 2.00mm ?U? notch cutter wheels are available. Ray-Ran is also able to offer wheels to customers specifications if required.

Standard features include
Advanced dedicated microprocessor control, Optical profile ground and diamond lapped dual tooth cutter wheels, Notches to any International test standard including Izod, Charpy, “U” and “V” notches, Notch depth dial indicator comparator, Slip gauge to set up the dial indicator comparator to accurately measure the remaining width under the notch, Micro adjustment notch depth, Standard notch depth setting blocks
Multi-sample loading, Setting rail forming an integral part of the vice to centralise test samples, Variable cutter speed with memory feature, Cutter speed range from 350 rpm to 2000 rpm, Anti-vibration linear motion slide, Variable metric and imperial traverse speeds with memory feature, Traverse speed range from 0.081 mm/rev to 1.0 mm/rev (0.003 in/rev to 0.04 in/rev), Fast return traverse speed, Easy to read digital speed liquid crystal display, Touch membrane keypad, Easy clean removable waste tray, Fully traceable certificate of calibration, Product user manual, CE mark of conformity, 1 year return to base warranty.

Test Description
Adjusted the settings for the notch depth and central position. Notch a test sample and measure notch depth. If necessary, make any fine adjustments. Multiple samples can now be notched.
