3D-printed gas turbine blade success

Siemens has received an award from the American Society of Mechanical Engineers (ASME) for its technological achievement with the first successfully 3D-printed and tested gas turbine blades.

Siemens kann mit seinem umfassenden Wissen in den wesentlichen Bereichen wie der Werkstoffkunde, der Automatisierung, dem Fertigungsprozess und der Verfahrenstechnik die Hochleistungskomponenten mittels Additive Manufacturing herstellen.
Siemens is able to produce the high performance components using Additive Manufacturing due to his broad knowledge in materials sciences, automation, manufacturing and process know how.

The components were tested at 13,000 rpm and temperatures beyond 1250°C, and featured completely revised and improved internal cooling geometry manufactured using AM technology. Siemens’ project team worked with blades manufactured at the company’s 3D printing facility in Finspong, Sweden, and at Materials Solutions, the recently acquired company in Worcester, UK.

Industry awaits SteelFab 2018

SteelFab 2018 gets underway next week (15-18 January) at the Expo Centre in Sharjah, United Arab Emirates. As the region’s most prominent business event specialising in steel fabrication, SteelFab 2018 will boast a large number of steel industry professionals and decision-makers among its exhibitors and visitors, as well as an interesting seminar programme.

The 14th edition of the show will present modern technologies in steel forming, metal-cutting, finishing, milling and heavy machinery, as well as other related engineering applications. SteelFab attracts worldwide attendance and participation both from national companies and hundreds of foreign firms and leading international brands in the field. XYZ Machine Tools and Chester Machine Tools will be among the 54 UK exhibitors at this year’s event. Around 8000 visitors attended the 2017 show from 83 different countries.

Kiwa HMCs exclusively at Dugard

Dugard recently announced that it is the new exclusive agent for Kiwa Machinery throughout the UK and Ireland. Based in Nabari, Japan, Kiwa is renowned for offering affordable yet state-of-the-art technology based on a strong R&D background.

OLYMPUS DIGITAL CAMERA

Specialising in horizontal machines, Kiwa says that its expandable tool and pallet technology sets the company apart from the competition, allowing for tailor-made designs to meet specific customer requirements. The tool changer and multi-pallet systems are upgradable on a retrofit basis, from a two-pallet, 120-tool machine, to a six- or eight-pallet machine with 220 tools. This gives customers the flexibility to meet any future expansion requirements without having to buy a completely new machine.
Kiwa machines feature high speed rapids (up to 80,000 mm/min on the KH-400 model) as well as direct-drive (up to 15,000 rpm) and built-in (up to 20,000 rpm) spindle options. What’s more, the patented hybrid slideway design of the machines, which combine roller and boxways, gives Kiwa horizontal machining centres both speed and rigidity.
A compact footprint is yet another distinctive attribute, at just 1.6 m wide for a 400 mm cube HMC with 500 x 500 x 500 mm travels in the X, Y and Z axes (Kiwa KH-4100). Cost-effective multi-pallet options are available on most models, as well as horizontal 5 or 4+1 axis configurations for optimum chip clearance.

Rigid yet compact machining centre

Burkhardt + Weber (B+W) has incorporated the stiffness and power of its heavy-duty MCX horizontal machining centres into a new, smaller model, the MCC 630. In so doing, the company says it has created one of the most rigid and powerful machines in its class for producing prismatic components weighing up to 1.5 tonnes (including the fixture). Availability in the UK and Ireland is through Geo Kingsbury Machine Tools.

The volcanic landscape with fields pahoehoe practically washed almost cover the entire surface of Santiago Island in the Galapagos Islands.

The four-axis machine (including C-axis rotary table), has twin 630 mm (optionally 630 x 800 mm) pallets and a nominal 1 cu m working envelope. External dimensions are 8 x 3.3 x 3.5 m.
B+W’s MCC 630 can deliver 1300 Nm of torque continuously if a 41 kW gear-driven spindle is chosen instead of a 30 kW/300 Nm motor spindle. There is a further alternative of a +45/-110° tilting spindle of identical power (also new), which adds a fifth CNC axis.
Spindle speed is up to 6000 rpm, optionally 10,000 rpm, while an ISO50 tool interface can be specified instead of the standard HSK-A100 with a tool clamping force of 45 kN. The tool changer serves a tool magazine with 64 pockets that can be doubled in size on request.
Productivity is promoted by a cutting feed force of 17.5 kN and 7 m/s2 acceleration to 60 m/min rapids in the linear axes, which are fitted with linear scales for feeding positional data back to the Siemens Sinumerik 840D sl control. B+W integrates a high level of Industry 4.0 monitoring and networking capability into its machines, offering data acquisition and communication for efficient production, process safety and timely maintenance.

Wele HMC500 launched in UK

The latest addition to the Wele range of machining centres is the HMC500 horizontal spindle model, which offers positioning accuracy of ±0.005 mm in the X, Y and Z axes, and a repeatability of ±0.003 mm over the full working strokes of 640 mm in X, 610 mm in Y and 680 mm in Z. With 60 m/min rapid traverse rates in each axis, positioning times are reduced, contributing to shorter cycle times and higher levels of productivity.

Launched in the UK by 2D CNC Machinery, the 500 mm twin-pallet machine (optional 400 mm pallet size) has a maximum workpiece capacity within a cylinder diameter of 750 x 900 mm high with a full B axis. The B axis has 1600 Nm of torque and a positioning accuracy of 10 arc-secs (with a repeatability of 6 arc-secs). Also featured is a zero-point clamping system via four radial pre-tensioned tapers to ensure alignment. Index times are 1.5 seconds with a pallet interchange time of 7 seconds.
The built-in 22 kW, Big-Plus dual-contact spindle has a speed range between 40 and 15,000 rpm with up to 167 Nm of torque available through a low and high-range transmission. Spindle acceleration and deceleration is 3.3 seconds. In order to minimise any deformation caused through variable cutting forces or thermal effects, the spindle head is mounted between twin box-type gantry columns, while the cast-iron bed is supported via three-point levelling.
There is a 60-tool magazine, providing 3 seconds chip-to-chip time, which is capable of carrying tools up to 80 mm diameter (or 160 mm with adjacent pockets left empty). Maximum tool length is 400 mm. Control is via Fanuc 0i-MF.
