Tube and rod end-finishing machine

according to the tube diameter and weight, and are made to slide on bearings to prevent noise and wear. The movements of the piece along the working axis are ensured by four self-centring mandrels, activated by synchronised hydraulic cylinders. A tempered and rectified precision helical toothed rack activates the advance, operated by brushless motor and precision reducer withslack recovery system.Themandrelsare designed to allow the machining of different diameters and sections, with no change of tools. An integrated floating system allows the compensation for a piece’s uneven straightness during machining, enabling precision machining even on particularly irregular tubes, and preventing dangerous mechanical stress on the mandrels. belts and de-burring wheels. Changeovers are easy and can be completed in minutes with four sets of tools covering a 5 / 16 " to 2" diameter range. Eight spindle speeds are available from 760 to 3,920 RPM, and the maximum stroke is 1¼". The end-finishing machines are easy to operate and offer a variety of accessory equipment and tooling options.

Manchester Tool & Die, Inc, USA, offers Pines Technology Model 660 tube and rod end-finishing machines for fast and simultaneous de-burring, ID/OD chamfering, and facing. There are two Model 660 variants, one manually operated and one air- operated, for finishing up to 1,500 ends per hour and 1,875 ends per hour, respectively. The end-finishing machines can provide cost savings by freeing lathes and other machines on a wide range of work. Model 660 can also increase production and improve accuracy compared to abrasive Dynobend BV, The Netherlands, manufactures a wide range of bending machines, specialising in custom-made machines to meet customers’ requirements. The company’s latest developments focus on the possibilities for automation in the bending process, for customers in industries such as heating/cooling, furniture and automotive. Automation can range from automatic loading to complete functioning production cells. In these production cells it is possible to work with loading systems, weld seam detection units, transfer units, robots, cutting systems, drilling/punching and even end-forming machines. Camera systems are used for checking bend quality, and can assist in creating a work cell with higher output. The company states that, providing bending is the main process, it is able to The tri-dimensional system allows operation on any point in a sphere space, while movement along five interpolated axes, with precision ball screws and linear motors, ensures high dynamics and performance. FL 600 3D is equipped with a double tube loading system: one from bundle, which allows the automatic loading of tubes with round, square and rectangular section and a loading capacity of 10,000kg, and one from chain, which also enables the loading of open section profiles. It is composed of V-shaped supports: the chains move at variable speed, The FL 600 3D from Tube Tech Machinery Srl, Italy, was designed for machining tubes and structural profiles with a maximum external diameter of 610mm and a maximum length of 24,000mm.

Tri-dimensional system with three CNC controls

The plant is automatically controlled by two CNC controls: one for the handling area and the other for the laser working area (Sphera). A third CNC control manages and supervises the laser source. The three computers are set to interact with one another, with no need for human operation: they automatically handle profile loading, dimensional control, 3D laser machining and discharge of the machined parts. The software is simple and user-friendly, and can be upgraded to include the handling of lists of materials and stock.

Custom-made bending machines

complete any working cell. When suitable machines are available, the company buys them and integrates them into the process. If the right machine cannot be found, the company develops one to fit the requirements. The bending machine in the process is the master, meaning that the

computer of the bending machine regulates all the other processes. Dynobend BV – The Netherlands Fax: +31 53 850 7731
