Processes for sheet metal cutting
erlcut cutting systems can be equipped with tools for plasma and oxy-fuel cutting. Furthermore, the machines can be extended with marking systems and drilling systems. The number of possible tool stations depends on the track width and the type of the tool carriage (driven or dragged).
Overview
- Plasma cutting up to 50 mm
- Oxyfuel cutting up to 300 mm
- Drilling, countersinking and threading
- Embossing system for component markings
Vertical and bevel cutting
Oxy-fuel cutting
As required, the erlcut can be equipped with one or more oxy-fuel tool stations. In addition, depending on the requirements, up to four different cutting torches are available, which differ in terms of ignition and height control.
- Automatic clamping (pneumatic) in multi-torch operation
- Proportional valve per torch for constant flame pattern even in multi-torch operation
- Max. cutting lenght standard: 200 mm
- Max. cutting lenght on request: 300 mm

Plasma cutting
erlcut cutting systems can be equipped with different power sources depending on the requirements. High-quality cuts are possible up to a cutting length of 50 mm. Depending on the model, the erlcut can be equipped with one or more plasma supports.
- Max. cutting length: depending on power source
- Power sources with an automatic gas console

Plasma bevelling
The plasma bevelling unit with intelligent initial height detection is designed as an entry-level solution for bevelling. The rotator unit is attached to a fully automatic z-axis on the gantry of the cutting system via a highly stable construction. The plasma bevel unit can be combined with other processes on erlcut gantry cutting systems.
- AC servo motors for high performance with low maintenance
- Intelligent initial height detection via tooltip
- Magnetic collision protection for the torch holder

Mechanical sheet metal processing
Drilling system erlcut-drill
erlcut gantry cutting systems can be extended by a drilling unit. The fully automatic erlcut-drill drilling system offers the possibility of drilling, threading and countersinking components before the actual cutting.
- 4/8/12-fold magazine for fast and manless tool changes
- Parking position for tool magazine protected from swarf and sparks
- Pneumatic downholder prevents slipping of the metal sheets
- Displacement measuring system for material thickness detection ensures high working speed and prevents errors
- Minimum quantity lubrication with oil-air mixture in fine dosage prevents build-up of frictional heat
| Plate thickness | 0 - 200 mm (automatic without adapter) |
| Tool changing | manual or pneumatic with tool magazine |
| Tool holder | SK 40 with Weldon surface clamping chuck |
| Drilling / countersinking | ∅ 5 - 24 mm |
| Threading | M6 to M22 (internal thread) |
Marking
Embossing system erlcut-sign
The erlcut-sign needle matrix embossing system can be used to mark components with the erlcut gantry cutting system. It can be used to create clear texts, lines and data matrix codes on the surface of the sheet metal plate.
- Thanks to its own x/y-axis, the embossing system works in a self-sufficient area without machine movement, which means that drives, pinions and racks are protected, and high working speeds are possible.
- The digitally controlled Z-axis guarantees highest repeat accuracy in the automatic control of the embossing process. In addition, it provides the full lowering speed depending on the material thickness up to the plate surface.
| Marking field | max. 150 x 100 mm |
| Marking height | 7 - 99 mm (depending on number of characters) |
| Materials | Steel, non-ferrous materials, plastics |
| Marking depth | up to 0.8 mm for mild steel |
| Air pressure | 2 - 6 bar (determines penetration depth) |
