Grease Lubricating 4500watts Machine Tool Brushless Spindle Motor Little Vibration


Structure features

1, High speed electric main bearing all use high speed angular contact ball bearing, axial sets pre-load to improve the support stiffness & grinding precision of spindle under high speed rotation.
2, Motorized spindle can use high speed grease and mist lubrication for different rotating speed
3, Temperature rise caused by high speed rotation, use coolant liquid circulatory system to remove
Instructions:
1. Water-cooled pipe needed to be connected with the motorized spindle while using, then launch
2. Use hand to turn spindle before operating. If there is any inflexible occur, Need to do trouble shooting then check the spindle rotation. It should be counter-clockwise rotation from motorized spindle side, if not, change over.
3. Cooling water used by grinding parts cannot splash on front cap of the motorized spindle before operating in case of burning the motor and bearing. Motor needs absolutely dry, when it is switched on, the cooling liquid can be used, when switched off, shuttle down the cooling liquid first then is the spindle motor.

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.

Description:


GDL125 series Motor Spindle is the automatic tools changing (can store encoder) spindle designed by our company. It adopts six-pole motor-driven system and the BT40 knife handle, could usually be used in the quick processing of different materials with 12000rpm. The multichamber protective measure including double-layer sealing device and air sealing conformation can efficaciously provide liquid from getting in and keep Motor Spindle working for a long time. The GMN import bearings and engine oil are used to ensure high performance of the spindle. Tool changing structure is advanced so that the signal and tool changing movement could be reliable and stable. The Motor Spindle can additionally store the encoder and have the rigidity tapping function. It can be used in the numerically controlled production center.


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.
