CARVING WITH TRACKING OF THE LEVEL OF WORKPIECE
The newest SAUNO Graphic-3KS machine has a unique milling technology with tracking the surface level of the workpiece.
Advantages of SAUNO technology:
- Milling on workpieces with an inclined and curved surface.
- Simplifies the work of the operator - the workpiece is not required to be installed in the machine exactly at the level.
- Processing of large stone slabs on the machine without using a table.
- Excluded uncontrolled fluctuations in the depth of processing. Reduces the load on the drives of the machine, increases the service life of the milling cutter.
The essence of the problem
The quality of carving is largely dependent on the accuracy of the workpiece. This dependence is especially pronounced when milling inscriptions, ornaments, and areas with variable depth.
Even a small tilt or bend of the surface of the workpiece leads to unpleasant effects. The video (see above) shows the result of milling an inscription on the centerline of the workpiece with a slope of +/- 0.7mm from the zero point in height. Where the surface is even a few tenths of a millimeter below zero, the lines of the inscription become thinner or completely disappear. Where the surface level is higher, the lines are thicker than required.
When milling, to get a good result, you must have:
a) workpiece with a smooth surface and the same thickness;
b) a machine with a perfectly calibrated worktable at Z level.
Problem solving - SAUNO technology
To solve these problems, SAUNO company has developed its own technology of milling with tracking the surface level.
Before carving, SAUNO machine scans the surface of the workpiece with an integrated level sensor. The Engrave software recreates the surface profile of the workpiece in the machining area. When milling, a height correction is constantly made to the path.
The level sensor is reliable and easy to use. Such sensors have been used for many years in SAUN0 impact engraving machines. At the end of the scan, the sensor can be easily removed upwards to protect against the coolant. The scanning process itself takes about 2 minutes.
