travelling bridge CNC machining centre
Large, flat components machined fast
Industry leading table-size-to-cost ratio
For OEMs in the metalworking industry flexibility is extremely important. This makes the Uniport 4000 the ideal gantry style machine for a whole range of applications, particularly for large and relatively flat components. This compact travelling bridge CNC machining centre is the smallest portal machine in our range and has a stationary machine bed and a movable bridge. The rigid construction and double cross rail ensure high stability. Options include split work zones for pendulum machining, an extra fast spindle for high-speed cutting, and more tool pockets.
- Dynamic features
- Easy to monitor
Tailor-made CNC Machine
The Uniport 4000 can be tailor made to suit many different requirements by adding custom fixtures and rotary tables for example. The ratio of table size to costs is one of the best in the industry and means all our customer specific solutions offer excellent value for money. Each one is based on proven Unisign technology, backed up by over 40 years of experience.
The 36 kW main spindle rotates at 12.000 rpm (option: 16.000 rpm) and features closed-loop cooling to provide high thermal stability. There is a double cross rail construction on the Y-axis for high rigidity, and electronic synchronised X-axes drives can be fitted to both sides to increase the rigidity even further. The working area of the large Y-axis can be extended to 3.500 mm.
Easy to monitor
The open bed design of the Uniport 4000 provides excellent chip flow as well as good visibility to help monitoring of the process. Automatic tool changes from the chain-type storage with 39 pockets are standard on the CNC machine.
This CNC machine, the Uniport 4000, is available with two main spindle configurations, 36 kW at 12.000 rpm or 16.000 rpm. The main spindle is equipped with an HSK63 or ISO40 interface.

CNC machine applications
- Oil & gas
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.
applications for aerospace
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.
applications for oil & gas -+
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.
