Description:

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. It adopts six-pole motor-driven system and the BT40 knife handle,

It can be used in the numerically controlled production center. could usually be used in the quick processing of different materials with 12000rpm.GDL125 series Motor Spindle is the automatic tools changing (can store encoder) spindle designed by our company.  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 Motor Spindle can additionally store the encoder and have the rigidity tapping function. 

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:

•  little vibration, good stability,Infinitely variable speed transmission for frequency changer with wide speed range, High rotating speed used for engraving and milling or fine machining. This product has wide application.
•  Constant power spindle with low rotating speed and high torque; Low rotating speed used for drilling and milling or rough machining;
•  Low noise, high processing precision
•  Adopt the ceramic core Aerial plug, more safe and reliable.

Notes for Use of Motor Spindle 

•  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. 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.
•  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.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. 
•  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.Coolant must be clean and free of grease.  Precision machining machine requires coolant temperature at 20 degrees positive or negative 2 degrees.
•  If just start using in high speed without running, abnormal noise and heat would happen then the using life will be shortened. In the process of saving and transporting motor spindles, the high speed grease in the bearings could be changed. 
•  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.
•  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.
•  The spindle should rotate in the specific direction.
•  Cooling the spindle by water cooling machine should control the temperature between 22 to 25.
