Cutting method
According to its material, the work may be cut wet (or with a cutting fluid),
or dry (or without a cutting fluid). The materials to be cut wet or dry are
listed in the table below.
Wet cutting
Use a water-soluble cutting fluid on this machine.
Select an appropriate cutting fluid by referring to Appendixes 1 to 3.
The main composition and characteristics of cutting fluids vary from
manufacturer to manufacturer. Some cutting fluids may adversely
affect the human body. For the main composition, characteristics,
effect on the human body, and other details, consult the manufacturers
of specific cutting fluids. Do not use cutting fluids of unknown
composition.
Oil-based cutting fluids may emit smoke or catch fire, depending on the
condition of their use. When using an oil-based cutting fluid on the
machine, strictly observe the following precautions:
• When the cutting operation is continued with an insufficient
discharge of the cutting fluid, the cutting fluid may emit smoke or
catch fire. Take care so that the cutting fluid is discharged in a
sufficient amount during the cutting operation.
• Some cutting fluids may degrade the cutting fluid hose. Periodically
inspect the cutting fluid hose for any leakage of the cutting fluid. As
soon as the cutting fluid hose is found to be leaking, change it.
• When covered with the cutting fluid, dust is very flammable. Be
sure to clean the machine every day.
• When the oil-based cutting fluid is used for cutting a flammable
material like titanium or magnesium, the risk of fire is much higher
than when a water-soluble cutting fluid is used. Strictly observe the
precautions described in "Cutting Flammable Materials" on page xvii.
• Install a fire extinguisher or other fire control device near the machine
to provide against a fire.
• Never leave the machine unattended during the cutting operation.
Never use oils other than cutting fluids (kerosene, for example) because
they have the high possibility of causing a fire.
