Orbital tube and pipe cutting and bevelling machines PROTEM tube cutting and bevelling machines are portable machines that are light, reliable, easy to use and they allow the user to get a perfect preparation with no thermally affected zones. They are composed of two rings: one fixed and one rotating. The tube cutting machines of the TT-NGseries are accurate in cutting and/or bevelling tubes and pipes of all schedules individually or in one simultaneous operation. These machines are especially designed to machine heavy wall tubes and pipes. They can have a pneumatic or hydraulic motorisation,with electrical drives on request. The machines are very robust and can be installed in various positions. Their split frame configuration allows their opening in two half-shells. For the manual clamping four independent adjustable jaws are used. The machines have a rear centring feature and completely enclosed drive gears for the operators’ safety. The TT-NG can be equipped with ovality copying slides enabling to correct the defects of ovality of tubes and pipes. They can also be remotely controlled for operations in areas under ionizing radiations. The machines of the Protem TT-NG series can machine pipes with diameters ranging from 60.3mm (2") up to 2,082.8mm (82") OD and over on request. Several configurations of tool holders are available including wheel holders enabling for example for the replacement of steam generators to cut on a 90mm wall thickness with severing tools and to cut the remaining 10mm with wheels in order to reduce the production of chips and thus contamination. Fast cutting SAWING bar or tube is a machining process that all too often leaves the operator to decide the speed of the blade and the downfeed rate, which means it is the operator who dictates the cutting efficiency and, therefore, the actual cost. However it is possible to take the guesswork out of the process and to achieve significantly improved production rates as well as longer blade life.  Danobat’s range of heavy-duty automatic horizontal bandsaws offers a maximum round cutting capacity of 420mm for the smallest model up to 1,100mm for the largest model.
