Frame for lasering, milling, etching, welding, cutting and engraving
Many people are looking for a laser cutter, CNC milling system, laser engraving machine . And here I am going to tell you about all the aspects you need to know about high-quality frame systems.
First of all, we need to understand that a frame or a gantry is a mechanical and electronic device that is controlled with the help of your computer . Or it can work independently performing business tasks such as cutting, engraving, milling, etching, etc.
There are a variety of frames: 2 axis, 3 axis, 4 axis, even 5 axis.
Most of 2 axis systems are used for color printing in XY plotters, for instance.
3 axis systems are well known as 3D printers and CNC routers.
As for 4 and 5 axis systems, they are rather complex and mainly used in industrial production including metalwork.
The main purpose of the frame is to position your laser, plasma, or mill to do the cutting, carving, etching, engraving, etc.
This is where the key aspect is. Depending on what you are doing, you will need 3 parameters: maximum payload, speed, and accuracy.
The payload parameter is needed to install a spindle on your frame, usually a Z-axis. If your spindle is heavy and powerful you need a higher payload. Especially, if you want to carve hard materials such as metal.
And the payload should be evenly distributed per each axle. The frame must be well-balanced.
Traveling speed and accuracy
The traveling speed of engraving and cutting speed is also very important since it allows you to operate during a certain period of time. Less speed – less work is done. More time needed. Of course, the parameters of the frame itself must correspond to the parameters of the laser or spindle. For example, if the frame can move at a speed of 1 meter per second. Then the laser or the spindle must be capable in operating with such speed. It will be quite pointless to add 1 watt laser on such a fast frame.
Accuracy is essential almost in every section of production, including jewelry, space, and aircraft industry.
It is hard to find any carving, cutting, engraving, or milling application when accuracy is not important.
By accuracy we mean the accuracy of movement, i.e. if you need to make a cut of 10.01 cm, and the device did 10.02, then we have here the accuracy of 0.01 cm or 0.1 mm.
On the other hand, the accuracy of the system itself is also very important. if the system worked and then returned to zero, it did not reach 1 cm, then this means that all work related to processing could be very inaccurate once such an error accumulated and has not been compensated.
