Hand Operated Charpy Notch Machine
The SPN-1R Hand Operated Charpy Notch Broaching Machine is designed for test houses and laboratories, which are producing small batches of test pieces in carbon steels, easily machined low alloy steels, non-ferrous and plastic materials.
This hand Charpy machine will cut Charpy and Izod 'V' and 'U' notches in pre-machined standard 10mm square, sub-size and 0.45" diameter specimens.
Hand operation makes it ideal for small batch quantities.
BROACHES Broaches are ordered separately.
Method of operation:
The broach is mounted in a square section rack and secured at the top & bottom by clamps. Adjusting screws built into the machine body are set to obtain the correct depth of notch and its position along the specimen.
Once set, the adjusting screws provide repeatability for the next specimen.
The broach can easily be removed, for re-sharpening or replaced to cut a different type of notch.
The sample is secured in the machine by two clamp screws.
A light coating of cutting oil is applied to the broach and then the hand wheel is operated which draws the broach through the specimen to produce an accurate notch profile.
After the notch has been cut, the sample is removed,
the broach raised and the broach teeth cleaned, ready for the next sample
