Description:

GDL80 series Motor Spindle is the automatic tools changing spindle designed by our company. It adopts four-pole motor-driven system and the ISO20 knife handle, could usually be used in the quick processing of different materials with Φ3~Φ10 blade from 24000rpm to 30000rpm. 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.
 

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 matrix, spectacles and jewelry.
 

Competitive Advantage:

1, Low noise, little vibration, good stability, high processing precision
2, Infinitely variable speed transmission for frequency changer with wide speed range
3, Adopt the ceramic core Aerial plug, more safe and reliable

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.
