Notes for Use of Motor Spindle:
1, 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.
2, 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.
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, The spindle should rotate in the specific direction.
6, Please refer to the instruction manual when store the spindle.
7, Cooling the spindle by water cooling machine should control the
temperature between 22 to 25.

Depth of parallelism within 0.002mm and Perpendicularity within
0.002mm are necessary. 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. 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.
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. 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.This product has
wide application.Low noise, little vibration, good stability, high
processing precisionInfinitely variable speed transmission for
frequency changer with wide speed rangeAdopt the ceramic core
Aerial plug, more safe and reliable .
Machine quality assurance last for a year,Bearing warranty last for
half a year.
Engraving and milling machine mainly used for the circular carving
and drilling and milling Applicable scope: This product is suitable
for Engraving machine orand Lock industry. It is of the hardware,
glassworks and woodworks.
