The flexible high-performance cutting machine Combi.cut 1 is the first concrete product that has been made possible by the new corporate structure with IMA and Schelling as subsidiaries of the IMA Schelling Group. The machine combines the splitting technologies of both sister companies in a completely new type of cutting system for processing coated chipboard for furniture production on a commission basis. During the development of the new system, the focus was clearly on maximum cost-effectiveness and optimal material utilization. This makes the new Combi.cut 1 the ideal solution for production systems with a capacity of 3000-4000 furniture parts per shift. With its small footprint of only around 123 m², it offers maximum performance and functionality in the smallest of spaces.
The Combi.cut 1 optimally combines the fast Schelling sawing technology for the precise and fast longitudinal division of the raw panels into strips with the flexible IMA milling technology for the transverse division of the strips. A third step takes place during the cross-splitting process – without any additional technical effort and with only minimal loss of performance. In this way, the new cutting system combined optimum adaptability with a high degree of manufacturing. Flexible cutting plans with contour strips and nesting ensure optimal material utilization.
The system is fed with raw plates or large residues via an external gantry with two horizontal axes and a vacuum load pick-up that can be rotated by 90°. The panels are placed in the correct position on the transfer table and aligned parallel to the X and Y axes. After that, the tray pushes the panel up to the sawing line and the splitting begins. Large remnants are returned to the transfer site. Sawdust, residues from trimming and waste strips fall through the saw’s waste flap onto a vibrating chute and are automatically transported away. A suction strip takes over the finished sawn strips at the strip pull-out and pulls them onto the brush plate of the downstream belt conveyor. The strips move into the transverse division via two further belt conveyors. The resulting temporal decoupling of the two cutting technologies allows the simultaneous processing of different raw panels in the sawing and milling areas.
In the milling station, which is equipped with five spindles, the strips are pushed against the transverse stops from the transverse divider insertion and aligned parallel to the X-axis. The movable X-clamps, which are pre-positioned according to the cutting plan, close and the insertion moves in the Y-direction to the processing line. The positioning of the spindles and the question of how often the splitting process must be repeated depend on the respective cutting plan and the number of depth cuts.
The separated parts are taken over by the strip elevator by means of a vacuum suction strip and positioned with the trailing edge on the subsequent transverse conveyor belt. Waste is machined or pushed into the waste flap.
With various options such as a thin parts package for panels less than 12 mm thick, a pusher with up to 9X clamps and a stationary tool changer, the cutting machine can be used even more flexibly. In particular, the tool changer allows additional work to be carried out during the transverse division. This includes, among other things, the insertion of seams, holes, grooves and notches as well as diagonal cuts. In this way, the degree of production of the workpieces after division is much higher than usual with a pure cutting. This allows the user to save an additional machine when manufacturing rear panels, for example.
The IMA Schelling Group offers the Combi.cut 1 in sizes 330 and 430 with a strip width of 1300 mm. A version with a maximum strip width of 1600 mm especially for the production of office furniture is being planned.
