Laser Drilling Line 1 (3 Lasers)
Three lasers in one line for high output
3 laser drilling machines in series
Max. glass size 2500 × 1300 mm
Glass thickness 3–12 mm
Total line length approx. 20.7 m
Glass enters on the infeed table and passes three laser drilling machines in series, which share the drilling work. The sheet is then washed, dried and stacked on the rack by the automatic unloading table.
Two to three operators per shift run the whole line.
Why customers choose this line
High output
Three lasers work on the same sheet in turn, so each machine drills only part of the pattern.
Dry, non-contact drilling
No drill bits, no cooling water at the laser, no tool changes. Round and special-shape holes from a DXF file.
Clean glass at the outfeed
Brush washing, three-stage spray and infrared drying. Glass leaves the line ready for the next process.
Automatic stacking
The tilting unloading table places every finished sheet on the rack and warns when the rack is full.
Safe by design
Class 1 enclosed laser, emergency stops along the line and anti-collision interlocks between stations.
Supported on site
MOKE engineers install, commission and train your team at your plant.

- 3
Laser drilling ×3
Each laser re-positions the sheet, drills its part of the pattern and passes it on.
- 4
Washing & drying
Brushes, three-stage spray and infrared ovens remove all dust and slurry.
- 5
Positioning for unloading
The clean sheet is aligned on the unloading table.
- 6

Modules and specifications
Module 1 · Automatic unloading table and transfer tables
At the end of the line, a tilting arm with vacuum suction cups moves the glass between the belt table and an A- or L-type storage rack. The table body travels on floor rails to the rack. Transfer tables convey and position the glass between the machines.

What your site needs to provide
Each module has its own electrical cabinet. You bring power, compressed air and water to each cabinet; MOKE supplies a layout drawing with every connection point marked.
Power (per module)
| Module | Supply | Supply rating (max.) | Cable |
|---|---|---|---|
| Infeed transfer table | 220 V AC single-phase (L, N, PE) | 1.5 kW | 1.5 mm² Cu |
