Product overview

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.

Spindle installation explanation

1.Circulating Cooling System Description

The system must ensure that the cooling water temperature of supply spindle is between 24-28 degree. Usually setting the flow switch in return pipe of the cooling system,to ensure the supply of spindle cooling water. Cooling water requirements: we recommend using distilled water, while recommend Feinuokesi (Fenix) protective agent F1 (using the scale of 1: 200),coolant temperature is 26 degree ±2 degree,inlet, outlet pipe temperature can’t exceed 5 degree.It is allowed As long as other monitoring can ensure fuller spindle cooling.

2.Air sealing control

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/m⊃3;
solid particle: <5µ m
Pressure dew point: <7.5degree (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 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.
 

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.

2.) 3.7KW SUNFAR brand Inverter 380V input with 380V output

VS500-4T0037G

 

​Description

key word: VS500 series inverter.Relying on its superior costefficiency, VS500 series general inverter is widely

applied in the industry of machine tool, electricity, textile, transportation, transmission,

paper, cable, metallurgy, etc.

The series product has been developed to be model in high stability, reliability after on-site inspection of

more than 700,000 inverters.

 

Features

1.Compact yet reasonable structure reduces the volume of inverter 20%-30% times than the traditional general inverter; independent cooling duct and closed main loop design

2.Droop control function: automatically balance power of drive system of inverters on the same transmission chain.

Adopts DC fan characterized by the large volume, high wind pressure, excellent cooling

effect and stable performance

3.Particular self-adaptive control technology, allowing for automatic current and voltage limitation and under-voltage suppression during operation.

4.Standard configuration of RS485 communication interface, optional MODBUS protocol and SUNFAR self-defined protocol; with linkage synchronous control function, allowing for easily communicating inverters with PLC,

industrial personal computers and other industrial personal equipments.

INPUT: 380VAC 3 phase

OUTPUT: 380VAC 3 phase

Power:3.7KW

3).BT30-ER25 tool holder with 45° pull stud
