Notes for Use of Motor Spindle 

• 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.
• 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.
• 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.
• 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.
• Please refer to the instruction manual when store the spindle.
• Cooling the spindle by water cooling machine should control the temperature between 22 to 25.

Description:

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. 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.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, Adopt the ceramic core Aerial plug, more safe and reliable
3, Infinitely variable speed transmission for frequency changer with wide speed range
