Imec processes first power devices on 200mm CMOS-compatible GaN-on-Si
Imec and its partners in the GaN industrial affiliation program (IIAP) have produced device-quality wafers with GaN/AlGaN layers on 200mm silicon wafers. With these wafers, functional GaN MISHEMTs were processed using standard CMOS tools.
GLOBALFOUNDRIES enters a broad strategic partnership with imec
GLOBALFOUNDRIES, one of the world’s leading semiconductor foundries, has signed a strategic long-term partnership on sub-22nm CMOS scaling and GaN-on-Si technology with the nanoelectronics R&D center imec.
Imec presents new GaN-on-Si architecture for enhancement mode power switching devices
At this weeks International Electron Devices Conference, the nanoelectronics research center imec presents an innovative, simple and robust GaN-on-Si double heterostructure FET (field effect transistor) architecture for GaN-on-Si power switching devices. The architecture meets the normally-off requirements of power switching circuits and is characterized by low leakage and high breakdown voltage, both essential parameters to reduce the power los...
Irish Manufacturer Expands High-speed Machining With 5-axis Acquisitions
As far back as 1998, Smithstown Light Engineering in Shannon, Co Clare, was in the vanguard of high-speed metalcutting, having installed the 12th machining centre ever built by the German firm, Roeders. The 3-axis, vertical-spindle machine has been in continual operation ever since and its 44,000 rpm spindle is still the fastest in the Irish manufacturer's factory.
Uprated conversational control cuts cycle times by a third
Two Hurco VMX30t vertical machining centres (VMCs) have been added to the subcontract machine shop of Schivo Group in Waterford, on the south coast of Ireland. Compared with a VMX42 installed in 2004, the latest machines are 50 per cent more productive, due entirely to the increased functionality of Hurco's conversational programming software, WinMax, incorporated into the control systems.
5-axis machining centre offers easy access
The new DMU 80 eVo vertical machining centre from DMG has an overhead gantry supporting the spindle head, resulting in exceptional accessibility to the working area, including from the side, even when an automated workpiece handling system is used. The design also provides a large 800 x 650 x 550 mm working volume in a compact footprint.
LARGEST MACHINING CENTRE FROM HERMLE
German machine tool manufacturer, Hermle, has added a new model, the C 60 U, to the upper end of its range of vertical-spindle, 5-axis machining centres. Availability in the UK is through sole agent, Geo Kingsbury Machine Tools, Gosport.
Six German Machine Tool Manufacturers To Be Promoted On One Stand
The very best in 3- to 5-axis machining centres, advanced mill-turning lathes and industrial cleaning machines will be promoted on the Geo Kingsbury Machine Tools stand at Aero Engineering 2011.
LARGE 5-AXIS MACHINING CENTRE HAS TURNING CAPABILITY AT ANY TABLE ANGLE
To reduce production costs and increase accuracy when producing complex parts requiring rotational as well as prismatic machining, Hermle introduced at EMO 2011 an 'MT' version of its largest 5-axis machining centre, the C 60 U, capable of turning components in the same clamping. Availability in the UK is through sole agent, Geo Kingsbury Machine Tools.
New Sliding Head Lathe With B-Axis
Traub, launched a new version of its 20 mm capacity sliding/fixed-headstock TNL18 lathe, with the addition of a 100-degree pivoting B-axis on the upper turret. The machine is available in the UK through sole agent, Geo Kingsbury Machine Tools. The machine is intended for the production of highly complex parts, particularly those needing angular milling and drilling operations, which no longer require the use of expensive and often inaccurate ang...
