“Zhong Hua Jiang” Brand story
How we started?
Huajiang was founded in 2000,starting in the production of CNC engraving spindle motor，then expanded production to VFD(Variable Frequency Drive) and engraving machines .
To explore and develop more market,we established Brand”Zhong Hua Jiang” on 2018.
What makes us proud ?
We have registered patent for our series of air cooling spindle motor .The patent No:200730184245.5.
We have 20 years manufacturing experience in this field.
We have been exporting our products to all over the world including well-known company in USA and Germany.
This spindle should be equipped with VFD 110V,400HZ.3HP, 2 Poles, Collet ER20(compatible with bits between 1/25" and 1/2" ) Diameter： Φ80mm，Voltage: 220V ,Power: 2.2 KW, Frequency: 400 Hz, Current: 8.5A,Weight:5.2kg( 11.5lbs), Speed: 5000-24000 RPM, Runout off: less than 0.005 mm.
Very quiet; Authentic 4pcs upgraded steel bearings significantly extend working life 3 times longer than ordinary spindle motor; Advanced dynamic balance technology effectively reduce the noise and increase stability in the working process; Runout off less than 0.005mm beyond expectation.
【EASY AND FAST TO INSTALL 】
We offer pre-soldered wire with aviation connector, it will take just 3 minutes to connect spindle motor to VFD.
Wood/ PVC/PCB/PMMA/Plastic/Aluminum carving/engraving machine, advertisement engraving machine,CNC router machine, small sized processing center, high speed centrifuge etc.
We have 20 years manufacturing experience in this field, any question or problem , pls contact us ,we will get you satisfied and get all problems resolved.
【Advanced dynamic balance design】
We adopt innovative & advanced dynamic balancing technology that effectively reduce the noise and increase stability in the working process.
Our scientific design of water cooled spindle motor makes low noise under high speed working environment.
【Easy and fast to install】
For your convenience , we offer pre-soldered wire with aviation connector that will be easy and fast to connect our spindle motor with VFD(Inverter).
There are 4 pins "1,2,3,4" on aviation connector. "1,2,3 " connect to "U,V.W" of VFD(Inverter) , "4" connects to ground.
【Extended working life】
We use authentic 4pcs upgraded of superior durability steel bearings and all copper lengthening coil of rotor for spindle motor that will significantly extend working life . In normal case, the working life of our spindle motor can reach 2 years for 8 hours/day.
【Anti-rust material , ordinary water as a coolant】
This offer is with Collet ER20-Φ6mm . ,Optional Collets are ER20(between Φ1/25" and Φ1/2").Our Collets provide high precision to spindle motor.
The water cooling hose is Φ8mm.
Just use ordinary water as a coolant .
Extra thick grease lubrication .
