Laser Cutting Capacity: A Guide to Thickness and Speed
Want to buy a laser cutting machine that would cut through heavy and thick pieces of metal in next to no time? Do you know what power your laser machine should have to implement the kind of accuracy you want? The most important factor that decides which power is suitable for the laser you want to buy is the material and its thickness.
Suppose, one laser can cut through a stainless steel metal piece of 10 mm width at a speed of 1.2 m per minute. Another laser can cut through the same piece of metal at a speed of 0.6 m per minute, then it would be wise to choose the latter machine because of its higher cutting speed.
Laser Cutting Capacity
The laser cutting capacity also depends on the type of laser cutting machine that you buy. There are three types of laser cutting systems that you need to know about:
1. Gas lasers
These are the traditional and oldest method of all times. It uses a technique called CO2 mixed laser. This type of laser is ideal for engraving on metals or cutting non-metal objects.
2. Crystal lasers
A crystal laser uses a crystal medium that has a tremendously high power to cut through metals. In fact, you can use it for both metal and non-metal objects. Although it has a high cutting capacity, it doesn’t last long. Investing in it would mean spending on a machine that will break down within a few years.
3. Fiber lasers
This is the latest type of laser that produces a focused, stronger, and more intense beam. It is best for cutting heavy metals, thus lowering overall production costs.
Cutting Speed on Different Metals
Let’s take three different powers of laser cutting machines and check out the speeds at which they can cut through mild steel, stainless steel, and aluminum:
1. Mild steel
You have three laser cutting machines with power IPG 1000W, IPG 2000W, and IPG 4000W, respectively. Here’s how much time they will take to cut a piece of mild metal of width 5 mm.
● IPG 1000W – 1.4 to 2 m/min
● IPG 2000W – 2 to 2.75 m/min
● IPG 4000W – 2.5 to 4 m/min
2. Stainless steel
You take the same three cutting machines to cut a piece of stainless steel of width 5 mm.
● IPG 1000W – 0.4 to 0.7 m/min
● IPG 2000W – 1.5 to 2 m/min
● IPG 4000W – 4 to 5.5 m/min
Finally, you take a piece of aluminum with a width of 3 mm and use the same three machines to cut it.
● IPG 1000W – 0.6 to 1.32 m/min
● IPG 2000W – 5 to 6.6 m/min
● IPG 4000W – 8 to 12 m/min
There are also more advanced models of laser cutting machines with higher power and cutting abilities. You can check their speeds and compare them with the thickness of the metal they can cut. That should give you an idea of which machine to buy.
