1. A jig and fixture is required.
There are many slots on it. A stack of glass with
several pieces of small thin glass is put inside
each of the slot. The total thickness of each
glass stack should be similar to the thickness
of each slot such that the glass stack is fix
and does not move inside the slot. Another glass
stack is put inside another slot until all the
slots are filled with glass stack.
2. When it is ready, the jig and fixture is
put on the rotating platform and is then fixed
by clamp or screw.
3. Water pump is started and water is sprayed
onto the glass stack for cooling during grinding.
Motor is started. Operator pulls down the handle
so that the grinding wheel becomes closing to
the glass stack until it touches the edges.
Then grinding is begun. After one platform rotation,
all the glass is edged.
4. If a fine edge is required, a polishing
wheel is used to polishing for a second rotation
of platform.
5. When ready, the jig and fixture is unloaded
and the glass stacks are removed. Another batch
of glass stack is loaded and the cycle is repeated.
6. If corner grinding is required, another
jig and fixture is prepared with the slots well
made such that the glass stack can be hold firmly
inside the slot with 45 degree tilted.
7. If high production is required, more jigs
and fixtures are prepared. After one jig and
fixture is edged, another jig and fixture with
glass stacks ready could be loaded right away
so that the machine could continue to edge to
minimize the downtime.
