Bending large parts from thick material

Amada has extended its range of HFE3i intelligent press brakes by adding a 400 tonne machine in 4, 5 and 6 m lengths. Aimed at heavy-engineering sectors such as agriculture, commercial vehicle, rail, construction, mining and shipbuilding, the new HFE3i HT (High Tonnage) model can bend mild steel up to 20 mm thick.

A high-rigidity frame offers optimum performance in high-tonnage applications, while Amada’s design of the lower table guarantees parallel beam deflection. Furthermore, the strong and flexible back gauge combines payload and positioning accuracy via its five motorised axes.

The standard single Delta-X finger, which can move forward and backwards independently of the other, allows high gauging flexibility and is particularly useful when bending asymmetrical workpieces. Optionally, customers can select Delta-X on both fingers.

HFE3i HT machines feature a range of equipment designed specifically for high-tonnage applications. For instance, Digipro uses wireless technology to transmit the measured angle to the control before the machine compensates to provide a precise bend angle. At all times, operators can use a hand wheel to make manual adjustments to each axis. If required, an optional device for active angle measurement is available: the Bi-M laser can measure and correct the angle in real time.

A further benefit for customers is Amada’s Eco inverter technology, which means the machine stops using power as soon as the bend is complete. As well as saving energy, this smart hydraulic power system reduces maintenance requirements, oil consumption and noise.

The HFE3i HT can be optionally fitted with Amada SF200 sheet followers (200 kg per arm) to help improve accuracy and safety. SF200 units follow the bend speed as folding takes place.

First engine run on Testbed 80

Rolls-Royce has successfully completed the first engine run on its state-of-the-art Testbed 80, which will be the largest and smartest indoor aerospace testbed in the world after its official opening in the coming months. With an internal area of 7500 sq m, making it larger than a football pitch, the testbed conducted its first run on a Rolls-Royce Trent XWB engine at the company’s facility in Derby. The project has been under construction for almost three years and represents a £90m investment.

Chris Cholerton, president of Rolls-Royce Civil Aerospace, says: “Testbed 80 will not only test engines such as the Trent XWB, but the engines and propulsion systems of the future, which will see us take another step towards decarbonisation. It’s great that the first engine test has been a success.”

Renishaw joins umati community

To continue providing customers in the CNC machining industry with vital data that helps realise the benefits of Industry 4.0, Renishaw has become a member of the umati community, which will complement its existing role on the standards committee of MTConnect. As an active member of both communities, Renishaw will support the development of common language standardisation for machine tools by publishing process measurement and part quality data.
The universal machine technology interface (umati) is an open standard backed by the German Machine Tool Builders’ Association (VDW) and the German Mechanical Engineering Industry Association (VDMA). Members of both organisations worked together in the development of a common information model, based on the OPC UA protocol, to simplify connectivity between equipment and software, and control data exchange between different machines.

Large-capacity Y-axis lathe

Components are becoming more and more complex, and drawing tolerances ever-tighter. The ability of a CNC turn-mill centre’s live turret tooling to move in the Y axis, as well as in X and Z, has therefore become increasingly important to facilitate high accuracy, one-hit machining. If travel in only the latter two axes is available, the milling of flats, deburring, and the possibility of machining pockets and off-centre features in-cycle, are either difficult or impossible.

The latest Miyano fixed-head lathe from Citizen Machinery UK to feature a Y-axis turret, in this case with all 12 tool stations driven, is the new BND-64SY for turning parts from bar up to 64 mm diameter. Joining a similar model that accepts bar up to 51 mm diameter through the main spindle, the 4.75-tonne machine is a mid-range, multi-purpose, twin-spindle turning centre. A ribbed monobloc bed slanted at 30°, and carrying precision-scraped square guideways, provides high rigidity, optimal thermal and mechanical stability, and excellent vibration damping, says Citizen.

These characteristics result in highly accurate machined components and longer service life of the tools, which can mount flexibly in the turret using multi-tool holders in any position. The robustness of machine construction allows the turning and milling of tough alloys and metals in their hardened condition, even when taking intermittent cuts. Polygon turning and thread milling are both options in the FANUC 0i-TD control, which is capable of simultaneous four-axis interpolation.

The specification of the Japanese-built machine includes turret travels in X/Y/Z of 175/75/435 mm, some 530 mm of sub-spindle axis travel, and up to 20 m/min rapid feed rate.

Pneumatic unloading system for Swiss DT26

The latest innovation from Tornos to support its sliding-head lathe customers is the pneumatic unloading system for the Swiss DT26 machine series. This new system avoids damage to any particularly intricate or fragile workpiece features.

For long workpieces with delicate features such as a fragile thread, the standard long-part system on Swiss DT and Swiss GT sliding-head machines may not provide the careful part handling required by the end user. For such types of workpieces, with a diameter up to 24 mm and a maximum length of 260 mm, Tornos now has a solution that enables delicate part removal.

Mounted on the tooling block for back machining, the system does not impair the possibility of using T510 and T520 tools. Ejection is via pneumatic operation, by using clamping jaws adapted to the respective workpiece type and material, ensuring there is no potential for part damage. 3D printing can facilitate jaw manufacturing, allowing complete customisation to the component form.

As a point of note, the system is equipped with sensors to monitor machine movements and provide optimum protection of the device. Furthermore, the design is such that it avoids interference with the machine’s counter-spindle.

With the addition of this system it is possible to keep a machine up to date and in conformance with customer component requirements, while employing only minor modifications. Tornos says that the retrofitting of existing machines is straightforward.
