Unisign CNC machine - Uniport 6000-HV


The portal machines in our Uniport series are particularly suitable if you need to machine large components from more than one side. Our CNC machines offer you the flexibility to do this rapidly and accurately.

Moving Column

For milling operations on products with a limited width, we have developed two vertical CNC machining centres: Univers 6000 and Unipro 5-L. These CNC machines are powerful all-rounders when it comes to milling.

Multi task

You will find many CNC milling machines with turning functionality added and conversely, many CNC lathes with milling functionality added. With our multitasking CNC machines you get the best of both worlds.


Your product might require a CNC machine to be developed specific to your needs. We have considerable experience building dedicated CNC machines for aerospace products, truck front axles, truck rear axles and forklift mast profiles.

Points for you to consider
Buying a CNC machine, how to make the right choice


CNC machining centres come in all shapes and sizes, so which one do you need? Just consider the difference between a CNC machine with a gantry, a CNC machine with a moving column, a multitasking CNC machine or one that has been built to your specifications. You want to make a properly thought-out choice, not least because a new CNC machine is a considerable investment. Based on our many years of experience and our expertise, we will help you make that choice. These are the most important points to consider when deciding which CNC machine is right for your manufacturing situation.

CNC machine tailored to your product

You are looking for a CNC machine and have Unisign on your shortlist. The first question we will ask you: what kind of products will you manufacture on a CNC machine? Do you have drawings, dimensions and product specifications? Using this information we will draw up a shortlist for you. Another important question we always ask: what do you want to use your CNC machine for in the near future? Is there a possibility that you will want to make larger products? Will other operations be required? We do our best to anticipate your future needs.

Your product dimensions

Naturally, the size of your product is the major determining factor when choosing a CNC machining centre. For lengths of 2 metres or longer (up to more than 30 metres with our CNC gantry machines) Unisign has numerous options for the X, Y and Z axes. We will give you relevant advice based on your product specifications.

Which metals?

You can deploy our CNC machines in almost any sector. From general machining to the oil and gas industry, the energy sector and truck and train manufacturing. You can machine a very wide variety of metals on our CNC machines. From normal grade steel to hardened materials, from super alloys to aluminium which has many applications in the aerospace industry.

Operations required

Do you particularly need CNC milling operations? And do you also need turning operations? And will 3 axis milling be sufficient, or does the machining process require 5-sided or even 5 axis simultaneous milling? You probably already have answers to most of these questions, but we would still like to answer these based on our experience. Often our answer differs from yours but rest assured: the outcome is always the best CNC machine for your product.

Product accessibility

An important consideration is the accessibility of the product to be processed. Perhaps this is challenging or even quite problematic for your product. In which case, we will recommend a CNC machine that allows for different machining heads. Such a machine automatically switches between a number of heads (right-angled head, 5 axis, product specific, etc.) and selects the head that can reach those awkward areas of your product. This in contrast to CNC machining centres with a fixed head, which makes you much less flexible.
An additional advantage for you is that at Unisign, we develop these heads ourselves and we can make them exactly to your specifications. With automatic head changing, long lead times due to repeated product clamping or the use of long ‘slow’ tools is a thing of the past.

Value added and turnkey

We not only provide added value with our CNC machines, but we also add value by integrating automatic loading systems, developing clamping fixtures and tools and help you with the production engineering. With a full turnkey project we take care of everything for you from A to Z.

High service level

When you purchase a CNC machine from us, you start from one of our ‘standard’ machines. A CNC machine with gantry, a CNC machine with moving column or a multitasking CNC machine. We then adapt it to create your new CNC machining centre which meets your specific needs regarding speed, capacity and operations.

Because we know exactly what goes on inside our CNC machining centres, we also know exactly how you can get the maximum possible benefit from your machine. Our service doesn’t stop after commissioning your machine. We provide extensive support with our detailed product and process knowledge and, in the event of a breakdown, our factory support team will help you resume operations as quickly as possible.

Requiring one of the highest chip removal rates in the market, the aerospace industry needs high dynamic machines. The Unipent4000 and Unipro5000 for example are ideal for volume production in this demanding environment and can remove 10 litres per minute of aluminium while maintaining the highest accuracy. For extra large parts or engine components, the Uniport6000-HV, Uniport7000, Unicom6000 and Unicom7000 machines offer the best solutions.

At Unisign we understand that our customers don’t just buy a CNC machine, they buy a process. And price per part is key. So for general applications we offer high torque machines with high material removal rates, including 5-axis and 5-sided machining and a choice of moving table or palletized, depending on the footprint available.

Pumps and valves for the oil & gas industry can be highly complex parts to produce with seals, gaskets, flanges and requirements like spiral grooves and elliptical conical eccentric turning. The machining centres from Unisign, with their high degree of automation and specially designed software, are a unique solution capable of milling parts that others cannot.

Heavy duty turning, milling and drilling characterises the production of components for energy-producing equipment like (wind) turbines. So you need a CNC machine that can take the load. A mill-turn machining centre like the Unicom6000, Unicom7000 and the Uniport7000-MTC or a multi-functional Uniport6000 and Uniport7000 are the ideal solution for producing these demanding parts.
