moving table machining centre
Multi-sided machining and automatic feeding of profiles
Precision and machining in pairs
Forklift mast channels constructed from rolled steel profiles can vary in length from 1 to 8 metres, so they need to be produced by a machining centre that combines high accuracy with a bar feeding transport unit. Since the 1990s, we have gained a lot of knowledge about machining these mast channels. We have translated that knowledge into a dedicated CNC machine: our Unimast. This vertical CNC machining centre offers you the highest levels of productivity, flexibility and safety, and what’s more, it’s easy to program and easy to use. It enables you machining in pairs of 4 or 6 profiles that are usually required for the production of a complete forklift mast.
- high uptime
- high flexibility
- Safety and operator comfort
The rolled, steel profiles are fed in pairs in our CNC machine and clamped by the double-executed, NC-controlled turntable. Just as in the assembled forklift truck mast, they are mirrored relative to each other in the double NC turntable. This enables you to process them both in a single operation. Furthermore, your material flow is a given, we ensure that our CNC machine fits in perfectly. Advantages like remote machine monitoring from Unisign’s own service centre ensure high uptime and a good ROI.
At Unisign, we are well aware of your challenges in forklift construction. U, I and other types of profiles with various cross-sections and in many different lengths have to be processed quickly and efficiently within your manufacturing process. Our dedicated CNC machine enables you to process steel profiles from 1 to 8 metres long and to rotate them along their longitudinal axis for drilling and milling on all four sides. Switching between profile types and the associated production programs is streamlined. No matter how wide your product range is, and with it the variation in profiles: you can process them on the same CNC machine.
safety and operator comfort
By utilizing a Unimast you’ll achieve considerable safety improvements. This CNC machine reduces the number of human interventions to a minimum. So you’ll not only reduce the risk of hazardous situations, you’ll also minimise the chanche of errors. What’s more, your employees are always at a safe distance and are fully shielded from the machining process. The work becomes less labour intensive for your operators. They place the profiles on the loader, or they are automatically retrieved from your warehouse. The barcode or other type of code on the profiles is then scanned, the correct processing program is loaded and the machine automatically sets itself up for the product. After machining, the profiles are transfered with a bar feeding system to the exit position for further handling.
This Unimast is a very powerful CNC machine, dedicated for forklift mast channels with automatic adaptability for many variations in profiles, flexible hydraulic clamping and the lowest cost per parts.

CNC machine applications
With over a million truck front axles being produced every year on Unisign machines it’s fair to say that we know what we are talking about in applications like these for the truck makers industry. We have established a world leading position by introducing the Unitwin6000, a CNC machine with two very powerful main spindles. The improvement in quality and reduction in cycle time is astonishing!
