Description:

Balance test should use the computerized balancer machine to check the precise balance of spindle with full speed. The assemble and install step is adjusted according to standard correction program when tightening the nut and is tightened by torque wrench within criterion, which make us not to correct the spindle by adjust the nut. Our high speed motor spindle utilizes hydraulic pull weights imported from German to measure the spindle’s pull accurately. The spindle leaving the factory is promised to run all for an integral test process so that the time of machine tool manufactors’ running time and machine tools delivery time could all be shortened.Assemble and install area’s temperature is controlled by the thermostatic air conditioner within accurate fit tolerance. The GDZ High Speed Motor Spindle researched and developed by our company has low noise and high accuracy characteristics. It adopts two-pole to six-pole motor-driven system and the spindle is made by the nickel chromium molybdenum alloying steels through standard heat treatment program to reach the requirement of high accuracy and stability. Depth of parallelism within 0.002mm and Perpendicularity within 0.002mm are necessary. 

Product features:

1, Adopt the ceramic core Aerial plug, more safe and reliable
2, Constant power spindle with low rotating speed and high torque; Low rotating speed used for drilling and milling or rough machining; High rotating speed used for engraving and milling or fine machining. This product has wide application.

3, The front end of the bearing use the water-cooling equipment , the cooling effect of the spindle is better. The durable years of the Bearings gets more longer.
4,L ow noise, little vibration, good stability, high processing precision
5,Infinitely variable speed transmission for frequency changer with wide speed range
 

After-sale protection:

Bearing warranty last for half a year,Machine quality assurance last for a year.

Notes for Use of Motor Spindle: 

 Coolant must be clean and free of grease. Temperature should be controlled in 5 to 30 degrees. If the ambient temperature is above 30 degrees, the cooling medium must be forced to cool. Precision machining machine requires coolant temperature at 20 degrees positive or negative 2 degrees.  In the process of saving and transporting motor spindles, the high speed grease in the bearings could be changed. So before using, the spindles should run in low speed for a period time at first. Running must start from the minimum speed of the spindle and add speed to differential growth by 3000rpm after 30 minutes. Each level is run in 20 minutes. If just start using in high speed without running, abnormal noise and heat would happen then the using life will be shortened. In the long-term use of the electric spindle, it should be working(in low speed) at least 15 to 30 minutes within one week.  The motor spindle must be preheated before processing every day. Until reaching the processing speed and running for 15 to 20 minutes, the spindle could start fine finishing. The spindle should stop 2 hours to prevent mechanical fatigue every day, so as to prolong the life.  Knock on the spindle end cover, collet and cutterhead when remove bit is forbidden. No bump in the process of saving, transporting and using motor spindles especially the end cover.  The spindle should rotate in the specific direction.  Please refer to the instruction manual when store the spindle.
