PRECISION MACHINE TOOLS
Cautions
Spindle nose cleaning
Air quality inside the air
compressor
Lube oil from the lubricating
pump (automatic)
Adding oil to the spindle oil
cooler and setting up the
temperature difference
Keep the taper of spindle nose and cutter shank clean at all
time to prevent dust or iron filings affecting the precision. The
spindle has an automatic dust removal function, but the
operator should wipe the parts with standard air-laid paper for
maintaining spindle precision.
The function pressure of this air compressor is 5kgf/cm²( 71
psi ). Therefore the air pressure source has to be at least 5.5
kgf/cm²( 78 psi ) and stabilized.
This machine has an air filter that eliminates impurities and
water vapor from the air. Air for the air pressure source has to
be clean and dry. Check the filter constantly to extend the
lifespan of the filter.
To effectively eliminates water vapor by the filter, drain the
water from the air tank of the air compressor. (Water drainage
is more effective in the morning).
Lube oil is released by the lubricating pump to lubricate the
guide ways and the lead screws. Insufficient lubrication may
speed up the abrasion and affect machine precision.
Always make sure that there is enough oil in the tank. If the
amount of oil is below the lower limit of the oil-level gauge, the
operation panel as well as the screen will issue a warning
message. Please add more oil as early as possible.
Oil cooling circulation system was adopted for the spindle to
effectively suppress spindle temperature increase and thus
extend the lifespan of the spindle. Use the correct type of
circulation and add more oil when the level is too low.
The machine adopts synchronous machine temperature
adjustment Temperature difference is set to 0 to prevent big
temperature difference, which can damage spindle bearing.
Do not change the value arbitrarily.
