Grease Lubricating 4500watts Machine Tool Brushless Spindle Motor
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
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
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
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.

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.
