The flexible high-performance Combi.cut 1 cutting centre is the first real product made possible in the first place by the new company structure with IMA and Schelling as subsidiaries of the IMA Schelling Group. The machine combines the panel cutting technologies of both sister companies in an entirely new type of cutting centre for processing faced chipboard panels in custom production of furniture. The new Combi.cut 1 is the ideal solution for processing plants with a production capacity of 3000 to 4000 furniture components per shift. With small floor space requirements of only 123 square meters, it provides maximum capacity and functionality on minimum floor space.
The Combi.cut 1 optimally combines the fast sawing technology from Schelling for accurate and fast rip cutting of raw panels in strips with the flexible IMA milling technology for cross-cutting of the strips. In the cross-cutting process, a third cut is made – totally without additional technical effort and with only minimum loss of capacity. In this way, the new panel cutting centre simultaneously increases both flexibility and degree of completeness. Flexible cutting plans with contour strips and nesting allow for panel optimisation.
Parallel processing increases capacity
Raw panels or large residual parts enter the work cell via an external gantry equipped with two horizontal axes and with a vacuum pick-up device rotatable through 90°. The panels are placed in the position required on the transfer table and aligned in parallel to the X and Y axes. After that, the infeed system feeds the panel to the saw line and the panel cutting process is started. Large residual parts are carried back to the transfer table. Sawdust, residual parts produced in the panel trimming process and waste strips fall through the waste flap of the saw onto a vibratory trough and are automatically removed from the cell. At the outfeed of the rip cut saw, a vacuum pick-up device takes away cut strips from the saw and carries them to the brush plate of the downstream multi belt conveyor. These strips are carried by two further multi belt conveyors to the cross-cut station. Hence, both panel cutting technologies are decoupled from each other, which enables simultaneous processing of different raw panels in the sawing and milling areas.
In the milling station equipped with five spindles, the strips are pushed from the infeed of the cross-cut station against the transverse end stops and aligned in parallel to the X axis. The movable X grippers pre-positioned according to the cutting plan close, and the infeed system moves in Y direction to the processing line. The positioning of the spindles and the number of repetitions of the cutting steps depend on the individual cutting plan and the number of depth cuts.
A pneumatic suction bar takes away the cut pieces from the outfeed belts and positions each of them with the trailing edge on the downstream cross conveyor. Waste parts are hogged or discharged through the waste flap.
Additional options increase flexibility
Various options such as a thin piece package for panels with less than 12 mm thickness, an infeed system with up to 9 X grippers and a stationary tool changer magazine can even further increase the flexibility of the panel cutting cell. In this context, especially the tool changer magazine enables additional operations to be carried out during cross-cutting. This covers, amongst other things, the machining of rebates, drilling of holes, production of grooves and cut-aways as well as diagonal cuts. Hence, the degree of completeness of the parts after the cutting process is substantially higher than that achieved by pure panel cutting. For example, for the fabrication of back panels, the user can do without an additional machine.
The IMA Schelling Group offers the Combi.cut 1 in sizes of 330 and 430 for a strip width of 1300 mm. A version with a maximum strip width of 1600 mm specifically for the production of office furniture is being planned.
