Having supplied Micro horizontal spinner transfer.

Precision Gear Technology of Hemel Hempstead with a GTG2 model gear and thread grinder eight years ago, Holroyd Precision, a division of the Precision Technologies Group, canvassed the company's Phil McIntyre for feedback.

The machine is used in the manufacture of worms, helical and spur gears and Holroyd is working with the company to develop bespoke worm software. The machine is used to grind worms from 15 to 250mm in diameter with a smallest gear of 0.6 to 526590 ipesearch.com/enquiry Single set-up system WELDING SYSTEM FOR ORBITAL FABRICATIONS Ash Safety assembles, services and hires out safety equipment, and provides City & Guilds-accredited training for users. However, company founder André Beard decided recently to move into the world of manufacturing.

He has also invested in test equipment that allows the Honiton business to assess and certify other companies' safety products, thereby creating an income stream as an approved test centre.

Before installing a new XYZ TC 320 LTY turning centre in 2011, various components were machined on a subcontract basis. This entailed holding stock to avoid problems caused by late deliveries, which impacted on cash flow and inhibited product design/development.

Beard ruled out the idea of a lathe and mill in favour of a turning centre with Y axis, driven tooling and 78mm bar capacity.

The Y axis of the TC 320 LTY, which has a 45hp main spindle capable of 3300 rev/ min, can travel 50mm above and below the centreline, making easy work of parts that would otherwise require separate milling and turning operations. Canned cycles cater for machining functions such as stock removal against contour. The simple conversational programming of the Siemens 828D ShopTurn control means the entire sequence from drawing to finished part takes the minimum of operator keystrokes.

McIntyre says: "The machine has been extremely reliable. It's incredibly accurate and will run all day for six days a week. Its flexibility is a major plus and, just as importantly, it's easy to use and programme with a new operator usually able to get the hang of things within just two weeks." GTG2 is a multi-purpose grinding system for volume or batch production of precision spur and helical gears, worms, screws and rotors.
