Drilling Milling Spindle Motor , Grease Lubricating Internal
Balance test should use the computerized balancer machine to check
the precise balance of spindle with full speed. Assemble and
install area’s temperature is controlled by the thermostatic air
conditioner within accurate fit tolerance The GDZ High Speed Motor
Spindle researched and developed by our company has low noise and
high accuracy characteristics. It adopts two-pole to six-pole
motor-driven system and the spindle is made by the nickel chromium
molybdenum alloying steels through standard heat treatment program
to reach the requirement of high accuracy and stability. Depth of
parallelism within 0.002mm and Perpendicularity within 0.002mm are
necessary. . The assemble and install step is adjusted according to
standard correction program when tightening the nut and is
tightened by torque wrench within criterion, which make us not to
correct the spindle by adjust the nut. Our high speed motor spindle
utilizes hydraulic pull weights imported from German to measure the
spindle’s pull accurately. The spindle leaving the factory is
promised to run all for an integral test process so that the time
of machine tool manufactors’ running time and machine tools
delivery time could all be shortened.
Applicable scope: the circular carving and drilling and milling of
the hardware This product is suitable for Engraving machine or
Engraving and milling machine and Lock industry. It is mainly used
for, glassworks and woodworks.
We offer one years warranty. Within warranty period, all exchanges
or repairment due to defects are free (Buyer is responsible for

1, Low noise, little vibration, good stability, high processing
2, Infinitely variable speed transmission for frequency changer
with wide speed range
3, Adopt the ceramic core Aerial plug, more safe and reliable
4, Constant power spindle with low rotating speed and high torque;
Low rotating speed used for drilling and milling or rough
machining; High rotating speed used for engraving and milling or
fine machining. This product has wide application.
5, The front end of the bearing use the water-cooling equipment ,
the cooling effect of the spindle is better. The durable years of
the Bearings gets more longer.
Notes for Use of Motor Spindle:
1, 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.
2, 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.
3, 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.
4, 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.
5, 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.
6, 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.
