Cup wheels double edger machines or lines.


These machines are using cup wheels. It means they are only able to carry out flat edge. They are mainly used for large batches and for glass over 8 mm (even if they are also used to work on 3 mm glass) when a good polishing is required.

The machines on the market are supplied with, 6, 8 or 10 spindles and more for each double edger side.

But the more popular machine is a 10 wheels (3 diamond wheels, one diamond and one polishing for each seam, 3 polishing wheels or 2 polishing wheels and a bright polishing wheel).

Machines with 11 wheels (4 polishing wheels) and machines with 12 wheels (same than the 11 wheels but with 4 diamond wheels) are also available on the market. But with a 12 wheels the diamond wheels position adjustment is not easy.

For the lines, a transfer is installed between the 2 double edger (on line or at 90°) and the squaring devices is installed on the second double edger which must to be the machine able to process the more important width (to have the more precise squaring).

To be able to put on line after the double edger line a more economical horizontal machine and to have only one operator on the line (for loading and unloading), generally another transfer is added after the second double edger.

Due to the market inquiry the suppliers propose more important machines (able to open up to 6 meters width)

Main options.

The number of options for the double edgers are very important, because they are very often customized lines.

Corner cutting spindles

There are 2 special spindles (one for each side and only on the second machine for a line) to edge the 4 corners of the glass (without polishing) to prevent glass broken during tempering).

Motorization for upper seams diamond spindles

To be able to adjust automatically the seams’width with the glass thickness

Motorization for the diamond spindles for the edge to adjet the spindle position with the tools wearing.

For this kind of machine the wheels wearing is very fast.




You must also to have a look on :

-How is done the replacement for the polishing wheels.

For this kind of machines you can have to change polishing wheels every day (on average a polishing wheels has to be changed each 2000 meters processing) and on a 10 spindles lines you have 20 polishing wheels!

-Speed and precision for the glass changing dimensions ( double edger opening and closing)

Mainly when you process small batches
