C-10 OUTLINE OF SYSTEMS
5.
PNEUMATIC SYSTEM
The pneumatic system consists of the air filter, regulator, air solenoid valve, and piping.
1) The compressed air supplied to the air supply port has moisture and dust removed from it by
the air filter, generating clean, dry air.
2) Next, the air pressure is adjusted to the appropriate pressure for the pneumatic devices by
the regulator.
3) The adjusted compressed air is sent to the air solenoid valves, which determine its route, and
the various pneumatic devices are operated.
6.
HEADSTOCK COOLING SYSTEM
The headstock cooling system consists of an oil cooler and piping parts. The headstock cooling
system is provided in order to keep the headstock temperature constant to maintain high
machining accuracy.
The headstock cooling system controls the cooling oil temperature with the temperature regulator
in the oil cooler so that it is equal to the room temperature.
The headstock cooling system starts operating when the power is turned on.
The trochoid pump in the oil cooler feeds cooling oil to the headstock to maintain the headstock
temperature at room temperature.
7.
SPINDLE BEARING LUBRICATION SYSTEM
The spindle bearing lubrication system consists of the pump unit, distributor, and piping.
The spindle bearing lubrication system forms an oil film on the bearings in the spindle to ensure
smooth rotation as well as to prevent wear of the bearings and heat generation.
The float switch, pressure switch, etc. are mounted to it.
The oil level in the oil tank and the variation of lubrication pressure are checked and if an
abnormality is detected, the corresponding error message is displayed on the NC operation panel
screen.
The lubrication pump operates for 15 seconds when the power is turned on. After that, it operates
at intervals of 16 minutes, for 15 seconds each time. However, the pump does not operate while
the spindle is not rotating.
The pump starts operating if the spindle starts rotating in order to feed the lubricating oil to the
distributor, where it is mixed with the compressed air and then supplied to the spindle bearings.
