Charpy Specimen Milling Machine (CNM)

The Blacks CNM range of machines have been specially designed to allow laboratories and test houses to produce their own standard and sub-size Charpy / Izod test pieces ready for cutting the appropriate notch.

 

Two variations of the Charpy Specimen Milling Machine (CNM) are available to cover a wide range of materials.

 

CNM-158A1 FIXED SPEED
CHARPY SPECIMEN MILLING MACHINE


The Fixed Speed Machine is recommended for customers who are producing specimens in carbon steels, easily machined low alloy steels, non-ferrous and plastic materials.

This machine has a fixed cutter speed of 1.98 m/sec(50Hz), 2.38m/sec(60Hz) and a variable feed rate for the samples of 2.5-9.0 mm/sec.

For customers producing specimens in a wider range of materials, see the CNM 140A1 with variable cutter speed.

 

CNM-140A1: VARIABLE SPEED
CHARPY SPECIMEN MILLING MACHINE
 

The Variable Speed Machine is recommended for customers who are producing specimens in carbon steels, more difficult to machine alloy steels, stainless steels, non-ferrous and plastic materials.

Please contact RJW Ltd if cutting superalloys.

This machine has a variable cutter speed of
1.0-2.5 m/sec and a variable feed rate for the samples of 2.2-9.0 mm/sec.

The varying of the cutter speed for differing materials improves the cutter tip life.
