8A Low Rotating Speed Water Cooling Engraving Spindle for All Engraving Software

Instructions for use

1) In use, must first connect the cooling water pipe, make spindle connect cooling water and then start.
2) Before driving, turned by hand spindle. If sensory block is not flexible, you should troubleshoot, and then check the direction of rotation of the spindle from the spindle end to see if the match should rotate counterclockwise power wiring should be changed to make it consistent.
3) Before driving, cooling water for grinding workpiece can’t be in the front end of the spindle cover, to prevent the front bearing cover slot inlet burning motor and bearing. the motor must not enter the water, after turned on of the motor, when you live in grinding the workpiece to open the grinding of workpieces coolant. First off the workpiece coolant shutdown, and then close the spindle motor.

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 machining machine requires coolant temperature at 20 degrees positive or negative 2 degrees.
4, 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.
5, 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.
6, 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.
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.
9, Please refer to the instruction manual when store the spindle.
10, Cooling the spindle by water cooling machine should control the temperature between 22 to 25.
11, 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.
