Main Features

l Gantry structure

1) Gantry framework: Welded with metal plates. It is heavy and resistant to deformation with high precision.

2) Laser head moves within various cutting field and the focused beam diameters are same at any locations and thus the cutting edge is also same at any locations.

l Convenient to align the optical route and replace lamp & rod

Just move the laser head to the edge of the table. The operator can stand by the side of the table to make adjustment, repair & replacement.

l Safe & convenient to load/unload the workpiece.

It is convenient to load or unload the workpiece since the table is at reasonable height.

l Unique laser cutting head

The focused beam is always kept at the focus since a self-floating laser cutting head is used. The distance between the cutting nozzle and metal surface is automatically kept unchanged whether the surface is flat, curvature or rough. The height of the nozzle to the metal surface will automatically change according to the metal .

l Multifunction

The maximum 1.5x3m metal sheets can be easily cut. Furthermore metal tubes can be cut using a rotary table.

l Easy transportation and installation

The whole machine can be easily shipped at package. Also the machine can be installed by the users according to our detailed operation manuals.

Advantages

l High precision & high stability

It combines precision ball screw and optimized CNC system, thus meeting the need of precision processing. Dynamic performance is stable and sustainable even for long time.

l Cutting is smooth & continuous

Step motor is used to move the cutting nozzle to keep the focus point unchanged during cutting, which meets the requirement for cutting flat or curved sheet metal.

l Applicable for large area cutting in multiple types of materials

Cutting thickness and cutting area are respectively up to 5mm and 3000mm×1500mm sheet metal. Materials suitable for processing include stainless steel, carbon steel, alloy steel, aluminium, brass, titanium etc.

l Cost-effective

It can replace CO2 laser cutting machine and plasma cutting machine at much lower cost.

l Low operation cost

Main consumables include electricity and assistant cutting gas, which are much cheaper than CO2 laser cutting machines.

l High cutting speed

l Low maintenance costs
