The MSE Scrap Chopper is a precision product, manufactured  to the same high standards as is expensive tooling.  Many customers ask why we hold such close tolerances on a machine that "will do nothing more than chop up scrap metal".  Our response is that tooling which pierces, shapes, and forms metal is expected to perform over a long period of time with precision and minimal downtime.  Our Scrap Choppers are working on the same materials in the same environments and are also expected to perform to a very high standard with minimal downtime. Therefore, we must manufacture our choppers to the same standards as those applied to expensive tooling.

Because our Scrap Choppers are operated by pneumatic cylinders, we have some inherent advantages over mechanically operated scrap choppers.  Some advantages are:

We do not consume machine energy to actuate our scrap chopper. Therefore, your machine experiences less wear and tear and is not subject to off-center loads.

Because we are controlling an air cylinder through an electric valve, we can equip the scrap chopper with a multi-stroke counter.  This gives the option to cut scrap on a predetermined number of

machine strokes, allowing the machine to cycle anywhere from 1 to 99 times between chopper actuations. As a result, less air is consumed and chopper blade life is extended.

We can completely detach the scrap chopper from the machine, mount it on a stand, and run it completely independent of the production machine.

Finally, for high speed applications, we can use a timer in lieu of a counter to control actuations of the scrap chopper.

As an added benefit, critical component parts of the scrap chopper are made of A2 Tool Steel and are heat treated to 60-62 rockwell.  Included in these parts is the moving blade which has two cutting edges.  As one edge dulls, simply rotating the blade 180 degrees exposes a new sharp edge.  The fixed blade has four cutting edges giving the option of rotating the blade 4 times between sharpenings.  Coupled with the fact that the cutting edges are held to close tolerances, these characteristics make this scrap chopper the best in its class.
