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.
 

Applications:

Applicable scope: This product is suitable for Engraving machine or Engraving and milling machine and Lock industry. It is mainly used for the circular carving and drilling and milling of the hardware, glassworks and woodworks.

Competitive Advantage:

Product features:
1, 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.
2, Low noise, little vibration, good stability, high processing precision
3, Infinitely variable speed transmission for frequency changer with wide speed range
4, Adopt the ceramic core Aerial plug, more safe and reliable
5, 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.

After-sale protection:

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

Notes for Use of Motor Spindle: 

1, Motor spindle should be compatible with frequency converter. The specification and parameter setup of  frequency converter should match the rated parameters of spindle. If not, spindle would burn out.
2, Before using the water-cooled motor spindle, it must be ensured that the cooling system is working properly and working without cooling condition is strictly forbidden. Cooling water calculate by 1 liter per kilowatt minute. The minimum flow rate of cooling water is not less than 5 liters per minute. The cooling water pipe and the water nozzle connection must be reliable to prevent leakage.
3, 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
