Re: Any "Best Practice" Recommendations for clearing chips and feed/speed when

In your recent post I noted your claim that THERMITE was known for
self ignition. This is WRONG. Thermite requires a ignition source
in excess of 1400 degrees. When it starts burning it will generate
temperatures of 6700 degrees F.

The problem many people in the metal working industry have had is
grinding swarf which contains both aluninum oxide and steel or
ferrous oxides, that thas dried and were ignited by heat generated
when maching without coolant.

This is a major problem. We were aerospace parts manufacturers and
have a lot of experience in this area. We have experimented to
ignite thermite in our scrap area and we needed either an oxy-
acetelyne torch, burning magnisium or an arc welding bachine. The
military uses an ignition train of magnesium oxide mixed with a
nitrocellulose binder in its THERMITE grenades. These are used for
the destruction of metal parts in the case you want to destroy items.
