Special cutting machines for cut and recut operations

New orbital flying cut-off machine

EMS, France, is the designer and manufacturer of special tube cutting and end-forming machines. The company supplies solutions for tube cutting and forming problems in the automobile, heating, sanitary and other tube related industries. The company’s EMS cutting machines are essentially used to recut bent tubes for applications such as exhausts. Alternative technology is also available to cut or recut hydroformed tubes. The model CT machine is used for chipless cutting without material tearing, fi EMS provide a range of cutting and end-forming machines

based on a combination of two knives: one vertical to pre-cut the tube, and one horizontal to make the main cut. The model CTR machine operates with a rotating head and recuts without burrs from inside to outside. EMS technology is based on a range of techniques including extrusion, expanding, reduction, pushing, segment head and mandrel forming. This is enhanced by the company’s own tooling developments. Acknowledged by leaders in the European automobile industry, the company’s tube end-forming and cutting machines are reputed for their robustness and reliability. Based on the highest quality hydraulic and electrical components, the machines are designed in accordance with user specifications.

MTM, Italy, has launched the new Comby orbital flying cut-off machine for a clean cut of heavy section tubes. The Comby range includes three models, covering outside diameters from 63mm to 323mm. The wall thickness on such applications is normally in the range of 3mm to 12.7mm. The main features of the Comby range include cold saw cutting process (clean cut) on heavy sections. The machine involves a simple cutting process, carried out by two combined axes for each cutting head. The Comby has electrically actuated cutting heads, that operate like a milling-machine. The machine employs small diameter HSS and TCT blades (independently from the tube OD). It also takes advantage of a rack and pinion carriage accelerating system.
