Description:

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. Balance test should use the computerized balancer machine to check the precise balance of spindle with full speed. Assemble and install area’s temperature is controlled by the thermostatic air conditioner within accurate fit tolerance. 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.

Product features:

• Low noise, little vibration, good stability, high processing precision
• 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.
• Infinitely variable speed transmission for frequency changer with wide speed range
•  Adopt the ceramic core Aerial plug, more safe and reliable

After-sale protection:

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

Notes for Use of Motor Spindle:

1, The spindle should rotate in the specific direction.
2, Please refer to the instruction manual when store the spindle.
3, Cooling the spindle by water cooling machine should control the temperature between 22 to 25.
4, The spindle using gas seal should dry and filter its gas source by the water oil separator before using. The atmospheric pressure is required to be 0.25MPa and filtering accuracy should be 5µm, or the bearing would be damaged.
