Laser Cutting Thickness And Speed Chart

The configuration of Laser cutting machine varies in different machines with respect to their speed, thickness, power, focus, pressure and diameter of nozzle. These parameters are much important to be discussed before going for any purchase of this laser cutting machine.

It is necessary to understand the relationship between these parameters and their effects. Like material which requires high power if kept under low power laser cutting it will produce burr on the surface and will produce poor quality cutting. For better understanding to these parameters and their relations we are providing you a detail chart which will guide you to select the right machine for your required material.

For a 1000W Laser cutting machine the thickness of material only ranges between 1mm to 12mm. For a MS material the maximum speed achieved can be 9 m/min whereas for an Aluminum and SS this is 25 m/min. This is because a low power machine do not offers high speed cutting.

Mild Steel restricts a 2000W Laser cutting machine. Material with thickness of 16mm can only be cut by this power where as low thickness materials vary their power below 2000W. This thing only affects a MS material whereas the rest use this standard power rating of machine as offers a high speed of 35 m/min.

For a power range of 3000W to 30000W the Laser Thickness and Speed Chart follow the same technique. Only the thickness level increases with increase in Power and same does the speed. But different gases like O2, N2 and AIR are used with these materials. MS material does not offer the maximum power range in all of the scenarios.

Other materials then MS offer wide range of cutting i.e. from 1mm to 100mm. This reduces the speed value to as low as 0.03 m/min.
Laser cutting technique is widely used in many industries as it provides highly efficient cutting and with now poor design. The power range varies from 1000W to 30000W but with this speed level also changes.

Conclusion

In this article we have present a detailed information regarding the relation of Speed and Thickness of a Laser Cutting Machine with respect to different power levels. It can clearly be observed that as the power increases the thickness level also increases, ,machine with low power cannot cut a high thickness material. It will either cause poor cutting or will destroy the cutting head.

Raymond provides you a complete overview between the inter relation of Laser Cutting Machine Thickness, Speed and Power. This guiding manual will help you get familiar with all these parameters and their dependencies. So, carefully reading it before you buy a Laser Cutting Machine for your material.
