- Which software is suitable for working with a portal milling machine?
- Which points are important when buying a portal milling machine?
What is a portal milling machine?
A portal milling machine discribes as the name indicates, a particular building type of a portal milling machine. Here, the X-axis is arranged horizontal, the Y axis vertical, and the Z-axis perpendicular on the two other axes, which together results in a so-called portal. Some portal milling machines have multiple milling heads on the Z axis, in addition to the milling head on the Y-bridge, to allow simultaneous processing of all sides in one step.
The workpiece to be machined is either mounted on a movable clamping table which moves within the portal in accordance with the desired material to be removed, or on a stationary clamping table which is traveled by the sled of the portal milling machine.
What is a portal milling machine used for?
a portal milling machine ist in der metallverarbeitenden Industrie weit verbreitet. Die stabile Bauweise führt zu weniger Vibrationen und somit zu einer hohen Genauigkeit in der Bearbeitung, nicht selten unter 0,02 mm in der Positioniergenauigkeit und Wiederholgenauigkeit.
Auch deshalb werden kleine portal milling machineportal milling machines gerne im Bereich des Gravierens, der Bearbeitung von jeglichen Oberflächen und der Erstellung von 3D-Formen in Holz, Kunststoff, Marmor, Granit, Stein und Metall eingesetzt. Ebenso sind Dosieranwendungen sowie Plasma-Schmelzschneiden und CNC-Schweißen, sogar Wasserstrahlschneiden mit einer Portalfräse möglich.
Der Einsatzbereich ist vielfältig und somit reichen die Anwender von der metallverarbeitenden Industrie über den Hobby Modellbauer bis hin zur Lebensmittelindustrie, dem Architekten und der Werbeagentur.
Durch die große Auswahl an austauschbaren Werkzeugen und die meist einfach zu erlernende Software Anwendung, findet die portal milling machine auch immer mehr Anklang bei Quereinsteigern und Hobbyisten.
Which software is suitable for working with a portal milling machine?
A portal milling machine operates like all milling machines with a so-called control software. What was manually done in the past with drawing paper and pencil, happens today, with much less effort, using a PC. Thanks to modern CAD (of English. Computer-aided design) / CAM (of English. Computer-aided manufacturing) control software, it is possible to send data sets, usually called DIN ISO G-codes, of almost any shape, whether 2D or 3D, to the machine. The machine then works row by row, until the workpiece has been processed as desired. Ready is your customized workpiece in no time!
When choosing the control software for you portal milling machine, a professional, experienced seller should give guidance in finding the right solution. Again, the advice applies:
The better all components are matched to one another,
the more efficient and accurat a portal milling machine will work!
It is recommended to contact a milling machine manufacturer or vendor for the purchase of a portal milling machine,offering for example free support even after purchase. This ensures that any initial difficulties, during incorporation into a control software are technical supportet by experienced staff, in order to avoid additional, high costs. This makes the start much easier and cheaper!
Alternatively, there is also free 3D CAD software.
Here is a current list:
When I decided to buy a portal milling machine, it may be important to pay attention to the following.
Which points are important when buying a portal milling machine?
You should ask yourself the following questions before buying a portal milling machine:
- What type of material do I want to process and how hard is it regarding the engine power of the milling motor? Hard or soft? Heat sensitive?
- What are the maximum sizes of my workpieces in relation to the size of my desired milling machine?
- Which quantities do I want to manufacture in one operation?
- How exactly do the features of my chosen portal milling machine match the needs of my workpiece to be processed?
- Do I feel well advised?
- Do I get expert support even after purchasing, possibly even free?
The more precisely you can define the requirements of the desired machine before buying, the more accurate a competent seller can offer the right machine, and then the more accurate the milling results will be achieved. In a professional, experienced company, you will always have a trained technician and / or seller.
