The machine could drill two holes in one line, the movement of workbench is controlled by an pneumatic device which could achieve distance setting, and equips moveable coordinate location which could control the holes distance in high precision tolerance. It applies to bulk production for the glass with two holes in one line.
Double surface automatic drilling which controlled by PLC drilling program.
The drilling apparatus adopts hydraulic buffer and pulse technique, which could drill holes rapidly and with good forming quality, no cracking around the hole.
For the different diameter hole, the tower type apparatus is adopted for adjusting the rotate speed of drill spindle.
Patent: Controlling by pulse device, Patent No: ZL200620126380.4
