Horn recently announced another milestone in the history of the Supermini with a sintered chip-breaking geometry for the Supermini type 105. Boring, profile turning, internal grooving, threading, chamfering, face grooving, drilling and slot broaching: The Supermini tool system can be adapted for numerous machining operations. 

Manufacturers of EV drive systems are leaving no stone unturned in their quest for quiet-running, dependable transmission gears and shafts. Where once chamfering and deburring operations were almost an afterthought, they’re now considered a primary soft machining process, with widespread recognition that anything less than a flawless tooth flank can result in premature transmission failure, less-than-optimal efficiency, and unacceptable noise.

The electrification movement is in full swing despite many obstacles still in play. Regardless of these challenges, machine tool providers are expanding their machine operations and tooling capabilities to meet the e-mobility demands of the future.

Capital Tool Industries (CTI), a leading gear-cutting tool manufacturer in India is pleased to announce the acquisition of long-established gear tool manufacturer Mico Tools (Mishalle NV) in Belgium. The acquisition extends the CTI footprint in Europe and expands its Gear Cutting Tools product line, especially the Power Skiving Cutters.

As a newly developed custom solution, a combination tool for heavy goods vehicle (HGV) freeze plug/water plug boring from CERATIZIT dramatically reduces cost and increases performance when producing the holes in cylinder blocks and heads. Such results are possible because the tool roughs, chamfers and reams/fine finishes holes in a single operation – even in grey cast iron with EN-GJV450 vermicular graphite.

It wasn’t long ago that cylindrical gear chamfering and deburring was almost an afterthought. Now the process ranks as high in importance as hobbing, shaping and grinding. Seemingly every gear manufacturer, particularly those developing transmission gears for e-drive applications, recognizes that anything less than a flawless tooth flank can result in premature transmission failure, less-than-optimal efficiency, and unacceptable noise. Thus, generating a chamfer to precise customer specifications is critical to minimize the potential for sharp, brittle edges after heat treat; avoid edge load situations in the gearbox; and eliminate excessive stock and hardened burrs in the tooth flank prior to the hard finishing operations (conditions which can greatly diminish tool life).
