To ensure an efficient cutting process, even for small quantities, IMA has used the powerful technology used in the BIMA Cutting Center in a new, more compact and less expensive machine.
The Performance.CUT provides optimum cutting performance at a lower price, even in small spaces. The precision cutting of rough cut components made from standard panels often develops into a costly process. Sawing technology struggles to produce workpieces in the order required. It results in a lot of leftovers and the process can be time consuming.
Nesting machines do not have these disadvantages, but produce a lot of costly sacrificial panels and the renovation that is sometimes associated with them. Considerable flows of exhaust air are required for effective chip removal, in order to create a reasonably clean cut.
The BIMA Cutting Center from IMA has revealed a long-established method for achieving production that is as effective as it is economic. This method, using milling technology, was designed for bulk quantities, combining the advantages of nesting machines with the speed of sawing.
A smaller version, the new Performance.CUT is now available and is the ideal machine for cutting 800 to 1,500 parts per shift, depending on the cutting plans involved. The result is a precise manufacturing method for continuous machining.
A milling cutter separates each blank from the standard panel at high speed. The automatic tool change ensures that blunted tools are replaced quickly. Unlike nesting methods, the Performance.Cut moves the starter panel in the Y-axis while the milling tool operates in the X and Z directions. This means that the cutting area is limited to one line. Sacrificial panels are not needed, and the Performance.Cut provides the possibility of nesting the cutting plans.
During the detailed design of this machine, IMA designers also looked at the issue of extraction. The aim was to construct as clean a machine as possible that would also produce a clean cut. To achieve this, the processing area was encapsulated and fitted with extraction at the top and at the bottom. Even limited extraction flow volumes are able to keep the cut parts and the machine free of dust and cut-offs. The reduced energy consumption used in extraction and optimal utilization of the panels makes the machine efficient in its use of resources. The raw board is guided by several grippers on the rear and one side edge of the panel.
The panels are cut safely and accurately until all the parts have been produced. The last separating cut to release a blank is always carried out when the workpiece is not moving and is securely fixed. The machine is very easy to automate. The support table is free from above for loading the raw board with the help of the loading gantry. The feed is by roller or belt conveyor and can be from behind or from both sides. The subsequent stacking can be done manually or with an automatic stacking system, or the parts can be transported on a conveyor.
Behind the output conveyor, a sufficiently large brush table is positioned to act as a buffer and the milled parts are re-assembled there in a manner similar in appearance to nested components. A handling unit can be used to rearrange, rotate, and realign the items. Where removal is by hand, the Performance.CUT has the ability to take leftover panels from the output side. The lateral grippers are then used in the output section.
The design of the standard panel feed, the treatment of remnants and offcuts, and the cut parts themselves can be individually adjusted to suit the operating environment, the degree of automation and output requirements.
Materials and workpieces in the machine are handled very carefully, making it suitable for all types of coated or foil-faced materials and also for raw particleboard.
