You should check coolant level in the coolant tank (chip plate) as soon as coolant is
being jetted from the coolant jet decreases. If coolant is not enough, add more and
make its level be over the sucking mouth of the cooling pump. If coolant is too dirty,
change the coolant in the coolant tank with the new completely. At the same time, also
clean inside of the chip pan.
 Cleaning of coolant filter
Take down the coolant filter and clean or change it.
7.4 Adjustment and Maintenance of the Machine
7.4.1 Adjustment of V- belts
The serving life of V-belts and bearings may be reduces if tension of V-belts is more than
allowable value. On the contrary, if the tension of the V-belts is too small, the V-belts
have not enough force to transfer rated power.
It is available to adjust the tension of the V-belts through moving the motor base upward
and downward. Proper tension of the V-belts should be determined by swag resulting
from loading the V-belts.
Adjust tension of the V-belts according to steps given below.
The belts shall be adjusted after the belts have been used for 3 months for the first time,
and later on, adjust them once every six months.
Adjusting steps:
 Pull the belt up at the direction vertical to the belt by hand. Applied force must be at
middle of the two pulleys.
 Screw up the four installing bolts on the motor base
 Screw the adjusting bolts to move the motor base, providing the belts with proper
tension.
 Cleaning grooves of the pulleys
The oil, dirty matter, dust or similar foreign matter in the grooves of the pulleys will
make the belts slip, shortening the serving life of the belts.
7.4.2 Adjustment of Spindle
Too large or too small clearance of spindle bearings can directly affect machining
accuracy of the machine. Rotating accuracy of spindle includes two items
：radial run-out
and axial slip. The radial run-out is guaranteed by the double-row centripetal short
cylinder roller bearings in front of spindle and centripetal thrust ball bearings at the rear
of spindle. Axial slip is guaranteed by centripetal thrust bearings at the rear of spindle.
This accuracy has been well adjusted before delivery of the machine, so you needn’t
adjust it in general case. If it is necessary to do adjustment due to turret’s impact or other
reasons, please adjust it according to following steps:
