How does a CNC machine work?
Milling a workpiece involves holding the workpiece to be machined in a horizontally mounted, adjustable spindle. As the workpiece itself rotates, various cutting tools (cutters) are applied to it to create various shapes and elements such as rings, grooves, slots, contours, radii, internal holes, threaded connections. On our milling machines, it is possible to work perpendicular to the workpiece of the milling machine, for the production of square surfaces, as well as for boring the inner holes of the rings. This expands the traditional processing capabilities.
3 and 5 axis machines.
In a three-axis machine, the above-mentioned cutting tool can move relative to the part along the X, Y and Z axes, but the spindle of the device can only be in 2 positions: horizontally or vertically to the workpiece itself. It is worth remembering that it is impossible to perform negative angles and some types of negative grooves in the product on 3-axis machines. On modern machine tools, the cutting tool can simultaneously move in any combination of 3 axes automatically.
A 5-axis machine is capable of performing all the same movements as a 3-axis machine, but with additional rotation around the X and Y axes. The way of rotation depends on the machine model. Usually, the workpiece rotates around the tool, not the cutting tool itself. But there are CNC models where the second version of this combination is also implemented: the rotation of the cutting tool around the workpiece. This does not affect the quality of the product and the surface, but only partially on the time of some operations. 5-axis machines offer much greater machining capabilities than 3-axis machines.
Using our 3-axis and 5-axis milling machines, our trained technicians will advise you on the right equipment and processing method for each specific product. We will also supplement your project with 3D printing if it is impossible to manufacture some parts on CNC.
Benefits of CNC technology
Surface and detail.
When milling, there is the possibility of finishing with the smallest tool available, which gives a perfectly smooth surface and detailing even the smallest elements.
Low ash content.
The wax used as a material is ideally burned out without leaving behind a deposit.
Quality and availability.
One of the cheapest rapid prototyping techniques while maintaining excellent detail and surface quality.
Disadvantages of CNC technology
Wax is very fragile. Some professionals have the skill of making rubber molds based on it, but it is very, very difficult.
Negative corners and undercuts.
Some negative corners and interior elements cannot be processed due to the corner of the cutter or lack of the desired projection.
