The two ZFA series gear grinders are designed to perform high-speed and high-precision finish machining on gears. The two models are each designed for a different gear size range, with ZFA160 capable of handling gears with an external diameter of up to 160 mm, and ZFA260 accommodating gears with an external diameter of up to 260 mm. Capable of meeting the increasingly sophisticated users’ needs, both ZFA160 and ZFA260 can mass-produce gears with a gear accuracy level equivalent to ISO 3 (JIS level N3).

With the new Automated Tool Production (ATP) system, Walter now offers a comprehensive automation solution for cutting tools. ATP networks grinding, eroding and measuring machines from Walter, as well as upstream and downstream machines from other system partners in the production process.

Overall developments and widespread public awareness of man-made climate change are transforming the way people think. The awareness has inspired a shift towards a more ecologically sustainable way of life. Driven by policymaking and technological innovation, ambitious efforts are underway to reduce greenhouse gas emissions to curb the rise in average temperatures. A key focus of these efforts is the mobility sector. 

Weiler Abrasives has announced its new blending disc product lineup that is ideal for a wide range of blending, weld cleaning and polishing needs. The blending discs can help operations save time and money through faster material removal and longer product life in such applications as shipbuilding, structural fabrication and welding. 

The world of bevel gear grinding is a complex topic. How do you determine which grinding and dressing parameters to select for a desired surface finish? What type of grinding wheel should be used? What type of dresser should be used? How do all these factors affect the gear noise and quality levels? These are some questions that will be addressed in this article.

The Curvic coupling from the aviation sector is a critical component used in helicopters. Previously, the external helical gearing was manufactured on one machine and the curvic coupling gearing on a second machine. The external and internal cylindrical grinding was then carried out on a third machine in two consecutive process steps.

From the outside, Gallmar Industries, nestled into an Oshkosh, WI, neighborhood, looks like any unassuming, medium-sized gear shop. Then take a plant tour with Gallmar’s VP of Operations Kenan Zolota—and prepare to be amazed. The facility stretches on like the Army’s warehouse at the end of Raiders of the Lost Ark, with everything from gear cutting to heat treat, gear grinding to inspection, all under one roof. Gallmar’s breadth of product line is in evidence too: defense-related transmission gears, 60-in. diameter internal gears for mining equipment, axle components for fire/ rescue trucks five feet in length, right down to a bin of brass ammunition casings that Zolota says are a special order.

UK-based PTG Holroyd has announced that, in the future, all models in its TG Series of ultra-precise helical rotor and thread grinding machines will be equipped with the Siemens digitally native Sinumerik One CNC as standard.
