Notes?for?Use?of?Motor?Spindle:

1, 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.
2, 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.
3, When stored clamping tool on electric spindle, the collet , nut and tapered bore must be cleaned to ensure accuracy. The hilt is inserted into the collet must be greater than 15 mm.
4, 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.
5, The spindle should rotate in the specific direction.
6, Please refer to the instruction manual when store the spindle.
7, Cooling the spindle by water cooling machine should control the temperature between 22 to 25.

Description:

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 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. 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:

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

Competitive Advantage:

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. 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.This product has wide application.Low noise, little vibration, good stability, high processing precisionInfinitely variable speed transmission for frequency changer wit
