CNCGLASS glass straight line edge grinding machine is suitable for grinding the straight
edge and 45°corner angle of flat glass with various dimensions and thickness. It can be
used to implement such procedures as coarse grinding, fine grinding and polishing the
straight edge, as well as coarse grinding and fine grinding the corner angles at two sides.
One-time processing. Frequency control of motor speed in a wide adjustable range, and
the speed is changed smoothly. During the grinding process, you can adjust the feeding
speed as you want. With such advantages as advanced structure, high
precision, convenient operation and high operation efficiency, it is an absolutely
necessary tool for glass processing technique.
CNCGLASS straight-line edge grinding machine is composed of such parts as feeding rail,
glass thickness adjusting mechanism, glass support, principle machine and the discharging
guide rail.
The two hanging rings of the principle machine are used to lift the principle machine. A
hoister with the capability of 3 tons hoists the machine by using two steel cables, and then
places the machine onto the installation situation. After setting down the machine, remove the
two hanging rings.
Horizontal adjustment：
1) Horizontal adjustment of the principle machine
Horizontal adjustment of the principle machine is implemented by adjusting the position
of bolt 1, nut 2 and supporting disc A, so as to make the machine maintain in horizontal level.
2) Horizontal adjustment of the glass support
Adjust the position of nut 1, bolt 2 and supporting disc B, so as to make the glass support
maintain in horizontal level. When the horizontal adjustment is finished, fix the glass support
onto the floor with the expansion bolt 3, nut 4 and the opposite vertex nut 5.
3) Adjustment of the go-out guide rail
a. The horizontal adjustment of the go-in and go-out guide rail (the conveying guide rail) is
implemented by adjusting bolt 7.
b. The position the go-in and go-out guide rail located on the principle machine is adjustable
by adjusting nut 1 and nut 2 on the screw mandrel.
Connecting the cooling system：
Introduce the cooling water to the fluked joint 1 through a plastic hose with the inner
diameter ofΦ19. After passing through the fluent distributor 2, fluked joint 3 and a plastic
hose with the inner diameter of Φ13 in turn, the cooling water runs into the three-way joint 4.
Then, the cooling water runs through a plastic hose with the inner diameter ofΦ12, and at last
goes into the cooling equipment 5, so as to cool down 8 or 9 grinding heads. Then, use a
plastic hose with the inner diameter of Φ50 to make the cooling water run back to the water
tank be used in duty-cycle operation. Besides, the fresh water (with a hydraulic pressure more
than 0.5MPa) also can be used as the cooling water to cool down the grinding heads. But, in
this condition, the cooling water is discharged from the plastic hose, and does not go into the
next operation cycle.
Connecting the cooling pump：
The plug seat located in the right and back of the principle machine is the outlet for the
cooling pump of the cooling system.

Maintenance and Service
Lubrication
1) After running for a day, you should clean the machine, and paint the rust preventative oil
onto the revealed parts without painting or oxide coating. Apply the mechanical oil to
lubricate the sliding bar of grinding head rack as well as the slide plate chair.
2) For the mechanical step less variable speed unit, use the UB-1 dedicated oil for step less
variable speed unit to lubricate the variable speed components. It’s necessary to change the
original oil with HB-1# oil At an interval of 1000 operating hours. It should be noted that the
oil level can only reach the middle of oil mirror, and the oil amount can’t be excessive. For
the speed reducer, it’s necessary to inject ZGN-1 natrium lubricating grease (SY1409-77) at an
interval of 3000 operating hours, in order to lubricate the bearings and gears. For the worm
reducer, it’s necessary to change the lubricant oil at an interval of 3000 hours. Select the 350#
industrial gear oil (SY-1172-80) to lubricate, and it should be noted that the oil level could
only reach the middle of oil mirror.
3) After the grinding head motor running for 3 months, it’s necessary to remove the grinding
wheel. When change the reinforced seal (indicated as N..7 in the 10) of the motor, it’s
necessary to paint the seal with the ZB-3 barium lubricant grease（SY1409-16）。
4) For such components as the grinding head rack bearing, grinding head rack screw mandrel,
grinding head rack gear and main driving bearing of the chain, etc, it’s necessary to paint them
with ZG-2H compositive calcium lubricant grease (SY1409-16) at an interval of about 2-3
months.
5) For all of the chains, it’s necessary to paint the with ZG-2H compositive calcium lubricant
grease (SY1409-16) at an interval of about 2-3 months. If possible, it’s best to remove the
chains, and clean them with kerosene. When dried, paint them with lubricant grease and then
fix again for using.
6) For the guiding plates on the front and back transmission chain guide rail as well as the
stainless steel guide rail, it’s necessary to paint them with ZG-2H compositive calcium
lubricant grease (SY1409-16) at an interval of one month. When painting, you should remove
the front cover, then the left and right covers. At the corners of transmission chain, paint the
grease onto the transmission plate. Then, the lubricant grease shall be brought into the guiding
plate and stainless steel guide rail by the transmission plate running.

Resolving means for the electrical accidents
1. The voltmeter works improperly, and the indicator doesn’t shine
Check whether the power supply and the fuse sire is burned out, if so, change with a new
fuse wire and fuse tube.
2. The failure indicator lights, and the machine can’t be started up.
The motor is overloaded, and the thermo relay acts to cut-off the power supply circuit, so
the machine can’t operate. To resolve this accident, you should stop work for a while, and
then press the manual reset buttons of thermo relay from the first button to the tenth button. At
this time, the failure indicator blacks out. Then, the machine can be started up. If the failure
indicator it’s necessary to find out the cause why the motor is overloaded, and whether the
thermo relay breaks down.
