CNC High Torque Electric Motor with Automatic Tools Changing Bearing Water-cooling
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.

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.
Notes for Use of Motor Spindle
- The specification and parameter setup of frequency converter should match the rated
- parameters of spindle. If not, spindle would burn out.
- 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 cooling water pipe and the water nozzle connection must be reliable to prevent leakage.
- Coolant must be clean and free of grease. Precision machining machine requires coolant temperature at 20 degrees positive or negative
- 2 degrees.
- 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. 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 motor spindle must be preheated before processing every day.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.
