Milling-engraving machines differ in the parameters cutting speed and the stroke in the Z-axis, and capacity.
When choosing milling and engraving machine need to pay attention to the following parameters:
the speed of movement of the portal on all axes.
- the amount of power the spindle, which is equipped with milling and engraving machine.
- size of the working field of the machine and method of material handling.
- ratio of performance and accuracy of the receiving surface.
the Advantage of CNC milling machines over other manufacturing methods is the speed, accuracy and simplicity: it is enough to prepare the image file and load it into the machine and the machine will calculate how faster and better to even the most complex patterns.
For engraving use a plain round cutter, either specific engravers.
When working on a milling-engraving machine the 1 lead cutter, it is recommended to take not more than 5 mm per pass, with a 2-lead can be milled to 10 mm in 1 pass. When exceeding this depth may receive the charring of the cut edge.
Spherical cutters give a lower roughness of the machined surface due to less vibration during the cutting process.
cheaper options milling-engraving machines of the type SUDA ST-8070, Beaver 9AT2 and more expensive class to represent the type of machine MEII-2212S.
These milling-engraving machines are designed for different work.
SUDA has three undeniable advantages in terms of stiffness.
SUDA ST-8070 all iron, Beaver 9AT2 strut and beam portal aluminum.
Width of the portal SUDA ST-8070 less than 20%.
the SUDA is built on rails and Z Beaver 9AT2 on cylindrical.
have SUDA minor in all respects, defects:
