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.

The machine is of robust construction designed to be mounted on our specially designed bench or on a customer's bench.

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.

Applications

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.

Theory/Method

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 with 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.

The hand machine clamping device facilitates cutting of single notches in standard square, round and rectangular sub-size specimens. 

The use of an optional multi-notch attachment allows cutting of multiple notches in a sample to be produced.

Once the adjusting screws have been set, a cycle time of 40 seconds per sample can be expected.
