Top performance
High productivity in SAUNO machines is achieved by a whole range of methods:
1.Engraving speed.
In engraving machines, the speed of movement of the impact head is determined by the frequency of engraving.Frequency shows how many strokes per second the machine makes.
In SAUNO machines in amplitude and point modes, the engraving frequency reaches 400 beats per second, and in combined mode - 2000 beats per second.
2.High speed ensures excellent engraving quality and striking depth.
High speeds place high demands on the mechanics of the machine in general and in particular on the coordinate drives.
SAUNO machines use ball screw drives (ball screws). Tests carried out by SAUNO have shown that other types of drives, such as belt drives or racks, used in coordinate machines, do not provide stable engraving quality, especially at high speeds.
Over time, due to increased wear and tear when working in a dusty environment, traces of “machine” engraving appear on the engraving - lines and stripes. To make them less noticeable, you have to reduce the engraving step, that is, the distance between the lines.
But reducing the step means increasing the engraving time. For example, when the step is reduced from 0.300mm to 0.200mm, the engraving time increases by 1.5 times. The high-precision mechanics of SAUNO machines allows you to engrave with high quality at any step (resolution).

3. To reduce engraving time, SAUNO machine automatically divides the images into parts.
Engraving in parts can speed up work by 2..3 times on composite images.
See below for details about the partial engraving mode.
4. SAUNO machines are fully automated.
Operations such as repeat pass can be set before starting work to save time.
Partial engraving mode (cells)
Partial engraving mode speeds up the engraving of composite images, inscriptions, and frames by several times.
Let's look at an example.
A portrait, an inscription, a cross and a frame are engraved on a 60x80cm plate.
The time for engraving an image with a step of 0.300mm is:
-2 hours 20 minutes in partial engraving mode;
-5 hours 40 minutes in standart mode, with the machine engraving the entire image, passing over a black background from edge to edge of the frame.
Thus, engraving in parts is 2.5 times faster.
Answers to questions
- How is the picture divided into parts?
The image is divided into parts automatically without operator intervention.
The program itself determines the fastest route.
- Why doesn’t the program divide some pictures into parts?
The program does not divide the image into parts if dividing into parts does not save time.
For example, the machine engraves closely spaced letters as one whole.
