Gear hobbing on a lathe

Many consider gear production to be complex and expensive because of the need to acquire a dedicated machine. However, CMZ has released a special video and downloadable guide on how to perform gear hobbing on its CNC lathes. The content steers CMZ lathe users through all the basic gear parameters and cycles required to machine gears. Hobbing is a process to manufacture gears by the use of a tool known as a ‘hob’, with the geometry of the gear obtained by synchronised movement between the spindle and live tool.

XYZ appoints commercial manager

Chris Hellier, who has spent his career specialising in manufacturing has joined XYZ Machine Tools as commercial manager. He brings with him extensive experience across a range of industries, as operations manager at a leading automotive component manufacturer, and managing director at both a vehicle adaptation specialist and an industrial fan company. A common thread during all of these previous roles was his purchase of XYZ machines within their production environments.

“It’s fair to say that I had a good knowledge of XYZ Machine Tools prior to this opportunity,” he says. “That knowledge, combined with the chance to put my skills to use in what will be an all-round role of overseeing the ongoing growth and development of XYZ Machine Tools, made it a straightforward decision to take on this position.”

Hainbuch gets a grip on Irish market

The Irish Manufacturing Research (IMR) facility in Rathcoole has recently installed a new Doosan Puma 2600SY II turning centre with work-holding technology from Hainbuch at the heart of the installation.

Working in collaboration with machine supplier Mills CNC, Hainbuch installed its SpannTop mini quick-change dead-length chucks on both spindles of the Doosan Puma, with an 80 mm chuck on the main spindle and a 52 mm system on the sub-spindle. The SpannTop mini incorporates a chuck with a dismountable end-stop plate that ensures precision workpiece clamping without the pull-back effect. SpannTop mini permits quick changeover from outside to inside diameter clamping, or three-jaw clamping, thanks to the flexibility of the modular system.

IMR’s machining applications specialist Chris Judge says: “To demonstrate the full technical capability of the Doosan Puma you need to be using the best work-holding and tooling systems available, so we were delighted to see the Hainbuch system selected.”

The design of the SpannTop mini significantly reduces interference contours and improves tool accessibility, making it suitable for limited space work envelopes. According to Hainbuch, with its compact design and lower mass than alternate systems, the SpannTop mini minimises inertia loss when compared with three-jaw chucks. The dead-length variant installed on the Puma machine converts to a fully functional ‘bar chuck’ when the end-stop plate is removed. Providing workpiece clamping without axial movement of the clamping head, the SpannTop mini clamps workpieces with a short collar or shoulder, even providing part pick-off without the pull-back effect.

Hainbuch UK supplied the SpannTop mini complete with machine adaptions, changing guns and a complement of 10 clamping heads on each spindle for holding a complete variety of components.

Light at the end of the tunnel

The VDW (German Machine Tool Builders’ Association) expects production in the German machine-tool industry to grow by 6% to around €12.6bn in 2021. At the association’s annual press conference, chairman Dr Heinz-Jürgen Prokop (pictured) stated that the improved mood in the economy is raising the willingness to invest. “After two years of great restraint, there is now a strong need to make up ground,” he said.

China is proving to be the principal driving force behind the economic green shoots, particularly for the automotive industry. In Europe, too, the expectations are that investment will rise again by 10% after the major slump. Oxford Economics, the VDW’s forecasting partner, is predicting strong growth of 35% for orders in 2021. According to the VDW, there were already indications of this improvement in November and December.
