that combines all steps of hydraulic tubing (sawing, deburring, bending, flaring, cutting ring assembly and chamfering) in just one machine. To avoid leakage in hydraulic systems, a precise rectangular sawcut and clean internal and external deburring of the

tube ends are as important as the safe connection of all components involved. Whether by means of the Tubomat’s integrated cutting ring assembly device or by the optionally available flaring device, the tube working professional can perfectly master both hydraulic connection methods. The machine is available in two versions, with a tube diameter range from 6mm up to 48mm. All of the tube working features integrated into the Tubomat are also available as separate functions in compact and powerful table-top units. The Tubograt performs clean internal and external deburring of sharp-edged tube ends after sawing. The tube end is briefly pressed against the deburring tools and is burr-free within a few seconds. To provide safe cutting ring or flaring connections in hydraulic systems Tracto- Technik has developed table-top assembly devices for both methods. The Tractopress is suitable for fast and faultless cutting ring assembly, as the specific work pressure is automatically adjusted by set up of the tooling for each tube diameter. The Variomat is a combined working machine for cutting ring assembly as well as for flaring of tubes up to Ø 42mm. Because of very short set up times, this device is well suited if both tube connection methods are in use.

Latest 8-station end-forming machine from Grazioli

The Grazioli Group, Italy, has launched a new end-forming line for effective tube processing. Based on 40 years of experience, this new generation of special equipment has a strong structure, precision assembly, and strict controls. The result is high performance and long life ensuring a very reliable product. The advanced end-forming machine has 8 forming stations and is equipped with a new numerical control and Grazioli’s remote assistance with live video support. The machine enables automatic forming via 1 to 8 forming stations through one working cycle. It supports 8 spinning units that can ram, cut, and roll with the maximum tube capacity of 90mm. The forming ram force can hold 10,000kg with a maximum working cylinder speed of 0.7 seconds.
