Description:

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.  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. Our high speed motor spindle utilizes hydraulic pull weights imported from German to measure the spindle’s pull accurately. The GDZ High Speed Motor Spindle researched and developed by our company has low noise and high accuracy characteristics. 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, Low noise, little vibration, good stability, high processing precision
2, Infinitely variable speed transmission for frequency changer with wide speed range
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.

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, 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, Knock on the spindle end cover, collet and cutterhead when remove bit is forbidden. No bump in the rocess of saving, transporting and using motor spindles especially the end cover.
6, Cooling the spindle by water cooling machine should control the temperature between 22 to 25.
