Portal milling machines manufacturer

CNC-guided milling heads facilitate working on a large scale!

Portal milling machines guide the milling head, which is located on a cross beam, between two columns. The workpiece is fixed on a clamping table. Depending on the design, either the clamping table is guided through the portal or the milling head moves above the clamping table during the milling process. Portal milling machines for industry are used for milling large surfaces. This type of machine tool works according to the continuous machining method.

Requirements for the manufacturers:

Precision, durability and accuracy of fit are basic criteria for the selection of a manufacturer for portal milling machines. A manufacturer is only as good as his machines. Furthermore, nowadays it is essential that the machines have CNC equipment. This makes it possible to work much more precise and faster. Many years of experience in mechanical engineering is the basic requirement for a very good manufacturer.

In addition to milling machines, engraving machines can be personally inspected during a demonstration. Competent advice is in the foreground here. "Made in Germany" is in the foreground for many interested parties. Manufacturers must be able to develop complete solutions according to customer requirements. Short reaction times are welcomed by all customers.

What should be considered when choosing a manufacturer for portal milling machines?

Aluminium profiles offer comfortable quality. Most producers offer different sizes. When buying a machine, especially for industrial machines, you should make sure that the machine tool fits into the workshop. In the case of the frame construction, a protective cover should be included in any case. CNC machine tools should have a multi-axis machining concept. High-speed milling machines are in continuous operation and should have a direct drive.

The design should be maintenance and wear-free. The high-precision milling of small parts requires special knowledge and experience, especially in the field of micro-machining. Special attention should also be paid to the CAD/CAM software. End-to-end solutions are preferable for both prototyping and production itself. 3-D capability is an absolute must for many purposes.

All portal milling machines should be ready for mains connection. Excellent machine concepts with robust granite/steel construction with optimally matched control technology are in great demand. Of course, it always depends on the purpose. Table versions with corresponding 3-D technology are also in great demand. It is essential to ensure that the width and height of the workpieces match the internal dimensions of the gantry. Flexible solutions in terms of design and adaptability by the manufacturers are therefore in great demand.

What should be emphasized with regard to the motor?

The motor is the heart of every machine. When selecting the manufacturer, special attention should therefore be paid to a good, robust motor suitable for the respective application. The most common form is the stepper motor for smaller CNC machines used as portal milling machines. This drive is ideal for surface processing, engraving or 3-D development of forms in stone, plastic or non-ferrous metals as well as wood in use. Servo motors are ideal for certain applications.

What do manufacturers for the industrial sector pay particular attention to?

The most important thing here is the rigid design. This guarantees the positioning accuracy. The accuracy of industrially used milling tools should be up to 5/1000 mm despite the extreme dimensions of the equipment. The solid construction allows a certain insensitivity to ground vibrations. High dimensional accuracy, cutting capacity and surface quality are further quality criteria for the selection of manufacturers.
