Multi-Cut efficiency from Austria

pipe production line was a smooth process with the help of Linsinger and its technicians. The 50-ton machine has shown its pedigree from the beginning. With low tool costs and optimised saw blade life the Multi-Cut MC 4-610 cuts the burr- free inner and outer edges of longitudinal

AUSTRIAN machinery specialist Linsinger has produced its popular tube cut-off machine-series Multi-Cut for many years. Managers responsible for service and maintenance in tube mills often find that machines need to be repaired and improved more than suppliers some- times claim when they originally pur- chased the machine. This is something Linsinger specifically works to avoid. “We plugged in the Linsinger Multi-Cut and it has been running from the first minute,” said the manager responsible for the maintenance department of the German tube specialist Mannesmann Line Pipe MLP in Hamm. The Linsinger tube cut-off machine was first installed in 2004 and has worked continuously since then without a problem. The construction and installation of the cut-off machine into an existing

welded tubes in an exceptionally fast time. A logical develop- ment of the Linsinger cut-off machine Multi- Cut MC4, which works with four independent controlled drive assem- blies, is the Multi-Cut tube cut-off machine MC3, which helped to revolutionise tube cutting with cross- section dimensions of between 150 and 660mm. The stationary tube cut-off machine

costs, which, after often more than 20 years in use, clearly carry more weight than the costs for the machine itself. The MC3 also features fully automated tool changing, which is performed by a robot as soon as a certain number of cuts have been made. The robot changes all three sawblades in only 90 seconds. Over the lifecycle of the machines of approximately 20 years this can help to save more than half a year during three-shift operation. “Not only through accuracy but also due to its cost effectiveness the MC3 is state-of-the-art. The additional charge compared with conventional saws amortise within two to three years,” said Linsinger-CEO Hans Knoll, when he summarised the multiple advantages that many customers worldwide have enjoyed. The tube cut-off machines, Multi-Cut MC3 and MC4 from Linsinger, Austria have made tube cutting technology faster, more efficient and more economical.

MC3 is particularly suited to the sampling of tubes’ respective endcuts, and is deployed both for welded tubes and seamless tube mills. It possesses three smaller circular saws, which are fixed on a radial revolvable disc and deliver a tidy, ready- for-sale cut. Considerable shorter length of cycle results from the simultaneous engagement of all three saws in the tube and the rotation about 120°; the pure cutting time for a P110 steel tube of dimension 244 x 13.5mm is about eight seconds. Another essential advantage is that if one saw fails, the machine is able to continue the work without interruption to the schedule or changing of the sawing blade. Furthermore, the cutting time can be synchronised optimally to the sawblades, which benefits the cost effectiveness of the machine. Compared to the larger and more expensive sawblades of conventional steel circular saws, the Multi-Cut machine can be used with smaller and less expensively priced sawblades. When combined with the longer durability of the smaller sawblades this results in a reduction of the tooling
