The double-sided edge shaping machine ROBA Fusion has been developed for the milling of edges of furniture and interior doors.
- Interior work and joinery
- Furniture fronts producers
- Door producers
Modern „lot size one“ production puts high demands on production planning and technical equipment. Part of this is the formatting and edge shaping of furniture and interior doors. This is usually done by double end tenoner who have integrated all necessary milling and sanding units and enable high performance with components of same size. But here the necessary long machine construction has disadvantages for those producers who have to process completely variable part sizes. There is the need to empty the entire machine before you can make the next width adjustment.
It takes a smart solution to give furniture fronts, that come with completely variable outer dimensions to the shaper, a high-throughput edge processing. The ROBA Fusion from MB Maschinenbau tackles the problem with a completely new concept. In order to make the required fast width adjustment, the machine has been designed to be particularly short and compact. The faster the workpieces leave the machine, the earlier the adjustment. The needed position must be determined fully automatically in through feed.
The completely redesigned ROBA Fusion consists of a left and right milling unit carrier equipped with high-speed servo drives. On the infeed conveyor belt the furniture front width, which outer dimensions are unknown so far, is determined in through feed by means of two lasers. The determined dimension is communicated to the machine and the right-hand milling units move fast to the required position. The furniture front is drawn into the work area and as it passes through the zone, the edge contours are processed by four milling cutters.
Two 11KW HSK63 spindles per machining side, working in conventional and climb cut rotation, are each equipped with a tool changer with 12 free spaces. The required tool values have been stored beforehand in the tool list and used as the necessary information to position the units. This is done by means of high-precision and dynamic servo drives in high-speed mode.
A solid welded steel construction with a high-precision aggregate carrier, powerful spindle design, freely programmable milling speed, conventional and climb cut rotation of the tools and a sophisticated part transport by means of a driven top pressure system, ensure a high surface quality and dimensional accuracy of the parts. A jump control of the spindles ensures a tear-free milling of the door corners in the end grain area. If MDF shaping only needs one tool, the free spindle can be used for a sanding head.
In case the ROBA Fusion edge shaper is in line with a ROBA REP edge sander and a return system, that moves the fronts back to the beginning of the line to proceed the unprocessed two sides, you have perfect complete machining. With a capacity of up to 2,500 four-sided machined fronts per shift, without any adjustments, the ROBA Fusion / ROBA REP combination is a highly effective solution, that is extremely effective in regards of the needed footprint and budget.
