A new, CNC circular sawing system, called KASTOvariospeed C14, has been introduced for high production cutting-to-length of solids, profiles and tubes in automatic cycle. Manufactured by KASTO Maschinenbau, Germany, and available from the UK subsidiary in Milton Keynes, it is ideal for applications in factories and stockholding operations requiring a large product mix in medium size batches down to one-offs. It also has the flexibility for efficient sawing of mixed materials such as bar, flats and profiles. Productivity is said to be at least 15 per cent higher than that of the saw it supersedes. Designed for cutting material up to 140 mm diameter with carbide blades or high speed steel (HSS) blades, the machine has a heavy-duty base, ballscrew-actuated material feed, and a 18.5 kW, frequency-controlled motor with spur gear drive that adapts to the type of blade being used. Blades from 360 to 425 mm diameter may be used and kerf is 4 mm for HSS and only 2.7 mm for carbide thin-cut blades. If a machine runs unmanned for long periods, the infeed mechanism not only has to supply large quantities of material to the saw but also has to accommodate different material shapes (round, square, rectangular or profile). With the KASTOvariospeed C14, chain magazines are used with dividers to segregate different materials and shapes. The magazines accept material lengths from 500 to 700 mm and can be equipped with between six and 20 sub-compartments, fed by gantry crane or directly from a bar storage system. To achieve a small footprint for a machine required to cut long pieces, KASTO has developed a pulling vice that reaches under the saw blade and pulls the work up to 2 metres in a single stroke to the desired cutting position, a system that also allows short rest pieces of just 40 mm. After the cut, the pulling-type gripper transports the cut piece onto a swivelling table that brings the cut billets, trim cuts and remnants to the required discharge positions. Different additional handlings systems are available. Using a sorting arm, for example, cut pieces can be lowered gently into containers to avoid surface damage. Another alternative is automatic palletisation of cut pieces using a multi-axis or gantry robot, reducing the need for personnel to sort, stack and prepare consignments for shipping. The centrally located operator panel requires only a few keystrokes to enter the data necessary to fulfill an order. Up to 1,000 orders can be input and urgent jobs may be placed at the head of the queue if desired. Further benefits of KASTO's latest control are automatic calculation of the number of pieces per bar length; rest piece optimisation for maximum material utilisation; and interfaces to a computerised MRP system and/or for teleservice. It contains knowledge of the optimum parameters for cutting common materials with either a carbide-tipped or HSS blade, while information on sawing new metals can be input by the user. In addition to storing the blade speed and feed rate for a particular job, the operator panel can be fed with additional data to minimise idle time during the cutting cycle and so maximise productivity.
