Products Production machinery Laser chosen for its piercing technology
Accurate Laser recently opened its sec- ond subcontract laser cutting company in the UK. The success of its quick turn- around, small batch manufacturing facil- ity in the West Midlands has led to the replicating of this proven business model in Leeds. Growth is clearly anticipated and the investment in a TruLaser 3030 is seen as an essential component to the future success of the business.
This is the company’s first Trumpf machine. “I have purchased six laser machines in the past 10 years and all have served my business well,” explains com- mercial director, Jon Till. “However, I could not ignore the superior piercing technolo- gy and edge quality of the TruLaser 3030 by comparison with its competition.” According to Accurate Laser, the pierc- ing times on the TruLaser machine is up to four times faster during pulse piercing, this translates to three seconds instead of 12 seconds on some material. Small hole quality is better too, says Till. Trumpf T: 0844 482 0188

High temp air amplifier moves hot air
Exair’s new high temperature air amplifier, available from Good Hand UK, is said to offer a simple, low cost way to move high volumes of hot air to sur- faces requiring uniform heating while in a furnace or oven. There are no impellers or moving parts to wear out and it amplifies air- flow up to 18:1 at outlet.
The High Temperature Air Amplifier is the most efficient for pushing high volumes of hot air to points that typically remain cool. This special design is rated for environments up to 700°F (374°C) and its surface is pro- tected from heat stress by a mil- spec coating process (developed for the aircraft industry), allow- ing easy disassembly for chang- ing shims or cleaning. Efficiency is high and the sound level is low at only 72dBA. It is suitable for corrosive applications. Available in 1-1/4in (32mm) diameter only. Good Hand UK T: 01908 221151

Lean manufacturing theory gets put into practice ‘Eliminate waste and maximise efficiency’ - this was the overriding message given to a group of delegates at
the latest Lean Factory Group workshop, hosted in Andover, Hampshire. The Lean Factory Group, a consor- tium of seven suppliers to the manufacturing sector (iCart, Bosch Power Tools, Bosch Rexroth, K.Hartwell, Sick UK, SSI Schaefer and Spitfire Consultancy), provides manufacturers with hands-on advice and guid- ance on a range of innovative, yet practical lean manufacturing solutions to boost productivity. A demonstration manufacturing cell, set-up within SSI Schaefer’s headquarters, gave delegates the unique opportunity to see how an efficient working production line should look and run. The cell, created using the very latest developments in lean manufacturing technology, provides a highly effective, practical and visual way of educating manufacturers to the benefits of lean implementation. Top and tailed with a number of presentations on the theory and benefits of lean manufacturing, including value stream map- ping, Kanban boards and workplace design, it was the practical session within the production cell that gave visitors the chance to compare their own production plant and examine the operation behind a lean manufacturing cell.
The cell clearly highlighted the actions that add value within a production line and gave food for thought to current actions across a host of production lines throughout the country. SSI Schaefer T: 01264 386600

Enter 321 Lathe with lower live turret provides mill-turn flexibility
German machine tool manufacturer, DMG has launched a CNC lathe capable of single-hit production of complex, multi-sided components. Designated CTX beta 1250 TC 4A, the machine features a powerful upper B-axis mill-turn spindle and a conventional lower turret with live tool stations and direct drive. Compared with the single B-axis variant of this lathe, the new model with additional bottom turret is able to carry out more complex work at the main spin- dle. Either or both turrets can operate at the counter spindle if that option is chosen, or else simultaneous work at both spindles can be undertaken. Productivity potential has been increased by up to 50 per cent in the new lathe compared to the purely
B-axis version. The B-axis with its 12,000rpm motor spindle swivels by ± 100 degrees and is supplied with HSK-A63 / Capto C6 tools from a 24-position disc magazine, although an 80-position chain maga- zine is an option. The bottom VDI 40 direct-drive turret has a ± 40 mm Y-axis and 12 driven stations (optionally 16) capable of speeds of up to 10,000 rpm. All tool stations are equipped with the DMG TRIFIX interface, which offers reduced set-up times as well as increased tool precision and stability. The machine features widely spaced linear guide- ways to ensure high stiffness, and a thermo-symmet- rical design. These, together with cooling of main and counter spindle as well as the tool spindle, allow top precision machining, assisted by linear scales. Rapid traverse speed is 45m/min, raising productivity by keeping idle times short.

The 19in screen of the DMG ERGOline CNC enhances reading comfort, while SOFTkeys allow the integration of additional and more detailed status information. The Siemens ShopTurn 3G user interface provides G-code or conversational pro- gramming, or a combination of the two. DMG T: 01582 570661
www.gildemeister.com MARCH 2011 Factory Equipment Gear honing rings
increase productivity A new range of gear honing rings using specially fused abrasives, said to last virtually twice as long as similar con- sumables on the market, has been introduced by Tyrolit. Called MIRA, the products are available in the UK through the company’s Crick sub- sidiary in Northamptonshire. Not only do the rings last longer, allowing production machines to com- plete more gears before the tool needs changing, but cycle times are also claimed to be reduced as infeed rates can be increased. Both factors combine to raise honing productivity by up to 30 per cent, without the need for capital investment in new machine tools. Demand from the automotive industry for ever quieter vehicle transmissions means that tooth geometry and surface quality must constantly be improved. In the manual transmission of a luxury car, up to 70 per cent of the gear wheels undergo honing on the flanks. Finish- honing of large volumes of gears in their hardened state is therefore called for and it is this trend that prompted Tyrolit to develop new abrasive specifi- cations for its MIRA rings.
