Portal milling machines<\/h1>\n
\n
\n

Portal milling is ideal for the precise machining of large surfaces or for when different kinds of parts have to be obtained from one sheet of plastic. A portal milling machine has a vacuum bed on which a plastic sheet is secured. The spindle is attached to a portal construction, so it can move back and forth over the bed or product. This form of plastic processing is also known as vacuum milling.<\/p>\n<\/div>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n\n

Portal milling: a summary<\/h2>\n\n\n\n

The plastic sheet is secured by means of a vacuum: the vacuum bed has small holes through which air can be sucked. In addition, this vacuum can be selectively located by having the air sucked through different groups of holes. Our latest machine is so advanced that it can determine which areas need vacuum securing during milling so that the plastic is kept absolutely flat.<\/p>\n\n\n\n

An additional benefit to this method is that all the parts that are milled out stay fixed to the bed. We often use a\u00a0special foil\u00a0between the vacuum bed and the plastic so that the plastic can be completely milled through. This makes it possible to manufacture\u00a0very small products\u00a0without needing a second operation.<\/p>\n\n\n\n

The portal milling machines have a minimal cooling system through which we apply as little liquid as we can as efficiently as possible. This improves machining conditions and results in\u00a0shorter production times,\u00a0better surface quality of the plastic, and\u00a0less residue\u00a0during portal milling. In addition, this technique is sustainable and efficient.<\/p>\n\n\n\n

Our portal mililng machines<\/h2>\n\n\n\n

The portal milling machines we use fall into a special outlying category of CNC machine, which were often designed for the aircraft industry. These machines are very accurate and equipped with a high-speed spindle. They can accurately mill over a length of more than 6,000 mm to 0.03 mm.<\/p>\n\n\n\n

We have the following portal milling machines:<\/p>\n\n\n\n
