CNC210 Operating Manual
A:whether the cooling pump is working properly ,no noise, flow and rated value.
B:whether the cooling liquid need to be replaced:when the nozzle out of the water reduction,
should check the level of the tank, timely replenishment. If it is too dirty, please timely
replacement.
Clean the sediment in the cooling water tank in time.
7.4 Adjust and maintain of the machine.
7.4.1 Headstock
Factory has adjusted the spindle bearing preload, within a short period of time it do not need
to be adjusted.After been used a period of time , the bearing clearance will increases, leading to
reduce the precision of rotary spindle, influences the machining accuracy of the products.In
normal use, spindle bearing temperature rise shall not exceed 40 degrees centigrade, temperature
shall not exceed 70 DEG.Otherwise, the bearing preload should be re adjust.if the accuracy of the
spindle can not achieve the accuracy requirement, also need to adjust bearing preload.For paired
angular contact ball bearings, they need to be removed and in accordance with the standard
method ,and determination under the predetermined pressure inside and outside the ring height
difference, and cooperate with each other, re installed onto the spindle box, preloaded with radial
locking screws, locking nut, and check the spindle of the precision, adjust bearing installation and
meets the requirement of accuracy, running 1 hour, meet the highest temperature and temperature
rise requirements.
Attention: The personal who adjust of spindle bearing shall have the professional and
technical qualifications .Adjustment should avoid pollution bearing. Very fine dust and impurities
will cause bearing excessive wear. The series of machine spindle bearing box have two kinds of
position, front and rear ,please pay attention while adjusting.
7.4.2 Adjustment of multi wedge belt
If the tension of the belt is greater than the allowable value, it may shorten the belt and the
main shaft bearing life. Instead, the tension is too small, there is not enough friction force to
transfer the amount of power.
The first belt tightness inspection should be in 3 months and then every 6 months.
Please see the below chart, Pressing belt by hand in the direction perpendicular to the belt,
the force must be in the middle position of belt wheel.
PK between 15-22N, H in 16 mm or so, if it is too large or too small, it will need to be
adjusted.
Release motor mounting plate and mounting screws, adjust the motor mounting plate, you
can adjust the tightness of the belt, while please attention that the belt and any other parts can not
be touched.
7.4.3 The adjust of lead screw.
The ball screw and drive motor Z axis of the machine using direct coupling, screw
positioning using near the end of the motor positioning, only need to adjust the positioning end
bearing elastic.
7.4.4 the adjust of the clearance for the different planker (adjust the clearance of guide way)

CNC210 Operating Manual
Between small carriage and the carriage, carriage and bed ,the sliding surface are used angle
plug iron, the plug iron inclination to 1:100. Inclined plane with the surface after distribution
scraping, and ensure good contact, when the gap is bigger, you can use the screws at the ends of
the gradual adjustment of the position of the plug iron to adjust the size of the gap. After
adjustment the ends of the two screws should contact with the plug iron, in order to ensure the
plug iron rigid.Adjustment should be in a moderate gap, not only to meet the accuracy
requirements of the machine tool, see precision test list , but also flexible sliding. Friction is too
large, although the detection accuracy is good, but it will lead to wear too fast.
