Horizontal double spindle glass drilling machines
The first question to ask is : small or important series to drill? From the answer you have some clues about the drilling machine and options you need.
The majority of the glass drilling machines available on the market allows to drill an hole between 1000 and 1800 from the glass edge (it means you can drill everywhere your hole on glass between 2 meters and 3,6 meters lenght with such machines).

The second parameter is how is managed the rotation speed spindle adjustment. The main solution on the market are with pulleys and belt (not easy) or with electronic regulation. If you have small holes series on glass the electronic regulation is easier and faster to use (and you are sure your operator uses it!!!).
An other important point is the adjustment of the drilling point on the glass (laser, manual or automatic square..)
A lot of glass drilling machines for small series are very similar. These machines are generally well protected against water.
The working spindle stage for the inferior spindle is generally automatic. The one for the superior spindle can be manual or automatic.

If you have big series you must have also a look on
-Adjustment for the drill wearing
