Details:
1)This
spindle is built-in type spindle motor, built-in three asynchronous
motors,by the inverter control.As the spindle has a compact
structure,high power, big torque, small vibration, low noise
characteristics,so it can achieve high speed,high powe cutting,high
precision and high stability operation.
2)The
bearing of spindle use grease lubricated angular to contact
bearings,can be achieved lifelong lubricating within the life cycle.
3)The
spindle use forced coolling mode to coolling motor,front and rear
bearings.Coolant flow through the reasonable arrangement cycle
watercourse of the spindle body,thus can take the heat generated of the
spindle rotation speed, to achieve thermal equilibrium,let spindle
temperature within a certain constant value. External cooling device
effect:maintaining a constant temperature of the coolant.
4)The
spindle built-in PTC 140 temperature sensor(Technical parameters are
visible in other sections of this specification),you can read it anytime
if you need to protect the motor temperature.
5)The tool clamping methods:this spindle built-in automatic tool change device,shank form is BT30.

5.Spindle installation explanationSpindle installation explanation
1)Fan cooling system description
When
the spindle rotates, the rear fan system must be started to ensure the
correct supply voltage and the supply voltage is 12V.
2)Air sealing control(AS)
In
order to prevent water or impurities enters internal of the
spindle,spindle will have gas sealing device,the gas seal machine must
be started start with the machine at the same time.And the need to go
throughmulti-stage filtration.
3)Compressed gas quality requirements
The quality requirement of gas which is used in gas seals:
Oil content:﹤0.01mg/m³
Solid particle:﹤5µ m
Pressure dew point:﹤7.5℃(0.7MPa)
4)Running-in program instructions
Only
all monitoring issued no failures operational signals,at the same
time,all safety devices have been installed and working properly,then
allow start spindle.
Note:new
or spindlewhichis not used for a long time must to be running
slowly.First,start run spindle for half an hour as 25% of the maximum
speed,then increaseto50% of the maximum speed,to run 15
minutes,finally,increase to maximum speed.It’s need to check the temperature of the spindleduring the wholeprocess,spindle
will get hot, but not hot hand, if the spindle becomes hot, pls stop
the operation and contact our customer service department.
