Tube cut-off machine range THE Multi-Cut tube cut-off machine series from Linsinger is well established in the global market. For example, the Multi-Cut MC 4-610, with low tool costs and optimised saw blade life, quickly cuts the burr-free inner and outer edges of longitudinal welded tubes. A logical development of the MC4, which works with four independently controlled drive assemblies, is the MC3 tube cut-off machine, for cutting tube from 150 to 660mm Ø. The stationary tube cut-off machine is suited to the sampling of tube end-cuts, deployed both for welded tubes and seamless tube mills. It features three smaller circular saws, which are fixed on a radial revolvable disc, and delivers a clean, ready-for-sale cut. Shorter length of cycle results in the simultaneous engagement of all three saws in the tube, and the subsequent rotation about 120°; the cutting time for a P110 steel tube of dimension 244 x 13.5mm is around eight seconds. Another advantage is that if one sawing station fails, the tube line operation can be continued with the remaining stations, with reduced line speed. The cutting time can also be synchronised to the saw blades. According to the manufacturer, compared to the large and expensive blades of conventional steel circular saws, the Multi-Cut machine can use smaller and lower-priced disposable blades. The longer durability of the smaller blades enables a reduction of tooling costs, and the thin cutting width saves material. The MC3 also features fully automated tool changing, performed by a robot that changes all three saw blades in only 90 seconds. Based on a machine lifecycle of 20 years, the claimed time saving is more than half a year in three- shift operation.
