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 recision 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.This spindle uses air cooling to cool the motor and front and rear bearings. The wind is provided by the fan at the rear end, from the rear of the spindle through the inner and outer air slots directly to the front of the spindle, there by taking away the heat generated by the high-speed rotation of the spindle, achieving thermal balance, and keeping the temperature of the electric spindle within a certain value.
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.
Please note that when stopping the spindle, you need to wait until the spindle is stopped before using the tool, so as to avoid causing the spindle and the tool mechanism to be connected together and cannot be separated. When loosening the tool and broaching the tool, you need to return the air, and pls keep the air intake and return air during the whole work.
Spindle 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 through multi-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)
3. 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 spindle which is 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 increase to 50% of the maximum speed,to run 15 minutes,finally,
increase to maximum speed.It’s need to check the temperature of the spindle during the whole process, spindle will get hot, but not hot hand, if the spindle becomes hot, pls stop the operation and contact our customer service department.
