SAUNO laser-engraving machines
How does the SAUNO laser engraving machine differ from already known laser engraving machines on the market?
SAUNO company has developed several original technologies that can bring laser engraving on stone to a new, previously inaccessible level of quality and ease of use.
Distinctive features of SAUNO laser engraving machine
Traditional laser engravers
1.The diameter and depth of the engraved points are the same for the entire image.
2.The depth of all engraving points is the same.
When you try to increase the depth by increasing the power, points merge, halftones disappear, and the image becomes “flat”.
3.Images on stone after engraving require painting to increase the brightness of the engraving.
4.If the workpiece is of unequal thickness, manual adjustment of the level (distance from the laser head to the surface) is required. If the surface of the stone is curved or has depressions, such as after hand polishing, then engraving on a machine is almost impossible.
5.The focal length before each engraving is set manually using a template.
6. Combined machines ( laser+impact ) have separate control units and various control programs for laser and impact engraving.
7. Two-axis machine with two horizontal drives X,Y.
8.The machine is equipped with belt drives.
9.Before engraving, preliminary conversion (rasterization) of the image in Photoshop is required. If you need to resize the image, you need to re-raster it.
10.There is no mode for adjusting the picture on the stone.
11.There is no automatic traversal mode along the image contour.
Manual operations are required to define the contour.
A contour walk is done before engraving to check that the engraving will not extend beyond the workpiece.
Traversing the contour is especially convenient when engraving on shaped workpieces.
12.Connecting to a computer via USB.
Requires installation of USB drivers for Windows.

The diameter and depth of each engraving point depends on the brightness of the point in the original image.
Light dots are engraved stronger and deeper than dark dots.
This allows you to get more halftones when engraving.
The strength and depth of the impact is set in the control program and can be easily adjusted during operation.
Brighter points penetrate deeper.
In result, the engraving on stone is brighter while maintaining all the shades and halftones of the original image.
You can do engravings without painting on many types of stone
(such as basalt, Chinese gabbro or Shanxi).
For those types of stone where painting is required, the paint holds better due to the greater depth of the engraving.
System for automatic monitoring of the workpiece level surface using an electronic sensor.
When engraving, the machine repeats the profile of the surface, tracking not only the inclination of the workpiece, but also the bend (curved surface).
There is no need to level the workpiece.
Autofocus - automatic setting of the focal length by an electronic level sensor.
Forget about measuring templates.
Single control unit for laser engraving and impact-etching.
Three-coordinate machine.
Thanks to the vertical drive, Z axis can be easily adjusted to suit different stone thicknesses.
Ball screw drives on all three axis.
More accurate and durable than belt ones.
Converting an image to a raster in Engrave program - simply copy the image from Photoshop and paste it into Engrave.
You can resize the image directly in the Engrave program. Original rasterization algorithms to choose from, created specifically for stone engraving.
Adjusting the size and location of the picture on the stone. Specifying the shape of the stone - rectangular, oval or shaped. Setting the starting point for engraving in any corner, center of the stone or at an arbitrary indent.
Preliminary traversal along the image contour.
Automatic calculation of the boundary contour of a picture.
Connecting to a computer with a USB cable.
Does not require installing drivers on your computer.
