1)This spindle is built-in type spindle motor, built-in three asynchronous motors,Bythe 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 TOcontact bearings,can be achieved lifelong lubricating within the life cycle.

3)The spindle use forced coolling mode TOcoolling 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, TOachieve thermal equilibrium,let spindle temperature within a certain constant value. External coolingDevice effect:maintaining a constant temperature of the coolant.

4)The spindle built-in PTC 140 temperature sensor(TEchnicalparameters are visible in other sections of this specification),you can read it anytime if you need TOprotect the motor temperature.

5)The tool clamping methods:this spindle built-in automatic tool changeDevice,shank form is BT30.

Spindleinstallation explanation

1) Fan cooling systemDescription

When the spindle rotates, the rear fan system must be started TOensure the correct supply voltage and the supply voltage is 12v.

2) Air Sealing control(AS)

In order TOprevent water or impurities enters internal of the spindle,spindle will have gas SealingDevice,the gas seal machine must be started start with the machine at the same time. And the need TOgo throughmulti-stage filtration.

3) Compressed gas quality requirements

The quality requirement of gas whichis used in gas seals:

Oil Content:﹤0.01mg/m³

Solid particle:< 5 * m

PressureDew point:< 7.5Degrees C(0.7mpa)

4) Running-in program instructions

Only all monitoring issued no failures operational signals,at the same time,all safetyDevices have been installed and working properly,then allow start spindle.

Note: new or spindlewhichIs not used for a long time must TObe running slowly.First,start run spindle for half an hour as 25% of the maximum speed,then increase TO50% of the maximum speed,TOrun 15 minutes,finally, increase TOmaximum speed.It 's need TOcheck 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 serviceDepartment.

7) ProductTool ChangeSignalsdescription

sensor MODEL(0-24V, PNP), The spindle built two sensors.wiring Diagram is as follows:

1. Response broach knife signal, when theKnife handleIs hang,black sensor output signal;

2. Response loose knife signal, when theKnife jawsOpen,black sensor output signal;

2). 5.5KW Fuling Inverter VFD 220V

This VFD can be used for constant torque loads( such as hard starting:Air compressors, HVAC units)and variable torque loads(such as pumps, fans, etc). It can be used as a motor speed control and a phase converter. The input for this VFD is 1 or 3 phase as you like. You can control different speed when you use this VFD. Most of our customers bought this VFD from us TOuse for:Lathes, Mills, Car Hoists, Pumps Conveyors, etc. This item uses Sine wave PWN(SPWM )for the control system and performance excellently
