Description:


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 GDZ High Speed Motor Spindle researched and developed by our company has low noise and high accuracy characteristics. 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. ?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.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.

Notes for Use of Motor Spindle:?

?

1, Cooling the spindle by water cooling machine should control the temperature between 22 to 25.
2, 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.

3, 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.

4, Please refer to the instruction manual when store the spindle.
5, 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.
6, 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.
7, 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.
7, 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.
8, The spindle should rotate in the specific direction.
