1. Installation and Operation
(1). General construction (Fig.6)
The SM5C Straight Line Edging Machine consists of an Input Conveyor, Glass Support Rack,
Main Machine, and Output Conveyor. It is important to set the machine up on a level surface or
level it if setting up on an uneven surface.
(2). Lifting (Fig.7)
Two lifting rings are on the main machine and are the recommended way to lift the machine.
Use wire cables and a crane to lift the main machine to the installation position. After positioning
the main machine onto the feet (see below), remove the lifting rings. Install glass support rack, input
and output conveyors and pull rods.
(3). Machine Installation and Leveling Adjustment
•Set up 6Shock Absorber Feet as shown in the photo at right. Thread a
square-head bolt into each foot until it touches the metal plate inside the foot.
•Lift the Main Machine Body and install 6 Foot Pad Assemblies. Add washers
and nuts to each bolt but do not tighten them down yet.
•Place a level on the front conveyor guard. Raise the low side by turning the
square bolt heads clockwise until the machine is level, side to side. Now
adjust the rear feet to maintain a 5 degree tilt-back. This is the standard angle
to keep glass secure on the conveyors. The machine is made with the 5 degree
tilt built in. If the adjustment of the feet is not enough to get the machine level,
insert flat metal shims between the foot and the machine.
•With the machine level, tighten the top nuts down securely while holding the
square bolt head.
•Install the conveyors and assemble the feet onto the conveyor legs the same way
the machine was set up. Use a level on each conveyor. The conveyor can be
leveled further with its own adjusters. See Figure 10.
(4). Electrical Connection
•The power source box on the backside of the main machine is for connecting the
power source. Use 3-phase, 4-wire cables to connect the power source, and make sure there is a
good ground connection. Running the machine, check the conveyor running direction, in case
the direction is opposite from the direction on the switch, change one pair of wire connections.
Be sure the machine is wired according to local codes. You may want a licensed electrician to do
the wiring for you.
Caution: Before machines are shipped, all motors are connected for correct rotation direction;
do not change the motor connection at will.

Cooling System Connection
Ⅰ. Power Connection: Plug the water pump into the front socket on the right side of the machine.
There are two sockets. The water pump can draw power from either socket.
Ⅱ.Water pipe connection (Fig.11)
Use the ¾” (19mm) inner diameter plastic tubing to connect the cooling pump to the Water
Entrances. 2 adjustable water lines are directed at each of the 4 wheels.
Use 2.5” (63mm) inner diameter plastic hose to connect the drain water from the main machine
to the outside water tank.
See figures 17 and 18 for a guide to positioning the coolant nozzles for best performance.

(7). Operation
After machine installation, adjustment and connection, you can start grind set-up and testing.
Grinding wheel position adjustment
1. Turn the hand-wheels of all spindles counter-clockwise to move the wheels backward (away
from glass). The grinding positions where adjusted before the machine was delivered. Turning the
hand-wheel clockwise one full turn moves the wheel towards glass grinding position in 1mm
increments. 1 full turn = 1 mm.

2. Turn on the Main Electrical Disconnect Switch (8) on the left side of the control panel.
Voltmeter (7) indicates the power source voltage, check that the voltage is within specified range;
turn on Power Source Switch with Indicator Light (1). All other power should be off.
3. Put a piece of glass that is long enough to occupy Pos.1-Pos.5 wheel on the input conveyor.
Set the Conveyor Direction Switch (11) to the glass working direction (right to left), Activate
Conveyor Transmission Switch (10), the glass should start moving. Stop Conveyor Transmission
Switch (10) or Emergency Switch (9) when the front of the glass passes the Pos. 4 wheel.
4. Turn the hand-wheel of Pos.1-Pos.5 spindles clockwise to move the wheels toward the
grinding position until the wheel touches the glass (manually turning the wheels during spindle
adjustment will help you hear the wheel touch the glass). Record the indicator’s position and then
turn the hand-wheel of the spindles anti-clockwise to move the wheels away from the glass grinding
position.
5. Restart Conveyor Transmission Switch (10), when the glass leaves the main machine to the
output conveyor, stop Conveyor, Switch (10) or Emergency Switch (9).
6. Turn the hand-wheel of Pos.1-Pos.5 spindles clockwise to move the wheels towards the glass
grinding position back to the above-mentioned adjustment position that you recorded.
Grinding Testing
1. Now all the wheels are at Zero grinding position. You can now adjust the wheel position
according to the grinding amount desired. In normal operation, Pos.1 grinds about 1/32” of the
flat-edge grinding amount. Always test with the Water Pumps running!
2. Adjust the arris wheels in so they grind the desired amount of seam. Generally keep this to a
small amount of grinding.
3. Slowly adjust the No.4 polish wheel up to achieve the best quality polish.
4. Adjust the No. 5 polish wheel up to give the best final luster, start Water Pump Switch (15),
check the coolant flow and start the Motor Switches (14), start Conveyor Transmission Switch (10).
5. Put the glass that was used for adjusting the wheel position on the input conveyor. Adjust the
wheel grind position according to the indication on the Grinding Motor Ampere Meter (2).
Quantity grinding
1. After several test runs, all the wheels are in the best grinding position. Now you can start
quantity grinding.
2. Add about 1/2 pound of synthetic diamond coolant (Cat No. 2651005) to the 45 gallon tank of
clean water and start Water Pumps, Switch (15), and check that the coolant is flowing to the wheels.
Start the Motors (Switches 12-13-14), start Conveyor Transmission Switch (10). Adjust the
transmission speed according to the glass thickness and grinding amount. Put the glass on the input
conveyor.
3. Watch the indication on the Grinding Motor Ampere Meter (2) and make up the loss of
wheels if it is necessary especially on the polishing wheel. Lower Amp readings indicate less
contact with the wheel and therefore the wheel can be adjusted closer to the glass.

Caution: When changing glass thickness, back off the front arris spindle, #2, and slowly dial
in the amount of arris to be ground. This should match the rear arris grind, which should not
have to be changed when glass thickness changes.
Maintenance
(1). Check the electrical ground connection to guarantee safe operation before working everyday.
(2). After working everyday, sweep away broken glass pieces and glass grind from the water tank
then wash it and check the coolant pipeline for blockage. Clean the machine, use light oil on
exposed or unpainted areas. Lubricate the slide plate of the spindles and front conveyor with light
machine oil.
(3). Use special step-less reducer lubrication oil (Mobil SHC 630 Synthetic) to lubricate the
mechanical step-less reducer. Change this oil every 1,000 operating hours. The oil level should
show on the oil gauge to avoid high oil temperature. Add grease to lubricate bearings and gears of
the step-less reducer every 3,000 operating hours. Use Mobil #350 oil in the worm gear box and
change it every 1,000 operating hour. Oil level should be at the middle of the oil gauge or have the
box ½full.
(4). Grease the bearings, gears and sprockets of the right and left gearbox every 3 or 4 months of
operating.
(5). Change the water in the coolant tank periodically. Too much glass powder will block the
pipeline and pump, and affect the grinding quality, shortening wheel life.
(6). The machine is equipped with a Central Lubrication System for the pad slideway. It is located
on the lower right front corner of the machine base. Fill this reservoir with 10 wt. light oil and, after
the plastic lines have filled with oil, pump the handle 5-8 times slowly while the machine is running.
This will keep the pad slideway lubricated. Be sure to get oil onto the entire length of the conveyor
as it passes the oil tube. Perform this task every 2 weeks and vary the oiling as needed due to high
production or less use. The chain links will benefit from having grease applied to them with a small
brush. Remove the guards and operate the conveyor slowly while carefully brushing grease on the
links as they pass along the chain sprocket on the end on the conveyor.
(7). Check the front and rear conveyor pads periodically, when most of the conveyor pads have
worn seriously, all should be changed.
(8). Check the wearable plates of the slideway periodically; change them when most of them have
worn seriously.
