Cutting flammable materials
Chips of titanium or magnesium violently burn when they catch fire.
Once these chips burn, the resultant fire may explosively propagate
through surrounding chips. When an oil-based cutting fluid is used on
the machine, it may also be ignited and spread the fire.
When cutting such flammable materials, be sure to clean the machine of
accumulated chips at the start and end of every operation. During
automatic operation, stop the machine as required to remove the chips.
Take care so that the cutting fluid is discharged in a sufficient amount
during the cutting operation.
When cutting a flammable material, be sure to prohibit any use of fire in
the shop, install a fire extinguisher or other fire control device near the
machine. Never leave the machine unattended during the cutting
operation.
When carrying or disposing of chips, take due care so that they do not
catch fire. Be sure to prohibit any use of fire where the chips are
stored.
Cutting unknown materials
Before cutting an unknown material, consult the supplier of the material,
burn a small amount of chips from the material in a safe place, or follow
any other procedure to check to see if the material is flammable or not.
