Gleason’s Titan grinding machine line is designed to reduce finish grinding times on gears with diameters ranging to 1,500 mm. On a single platform, the machine offers both pure profile grinding for flexible single-part production as well as a combination of threaded wheel and profile grinding for faster, fully automated, large-scale production.
 
This process, called Power Grind, reduces gear production times by roughing via threaded wheel grinding before employing profile grinding to perform complex modifications and achieve optimal quality and surface finish.
 
An optional external setup table enables setup of the workpiece and workholding package to be parallel with primary production rather than sequential. To reduce non-productive time, the machine features an optional workpiece changer and a high speed toolchanger to automate loading and the exchange of a threaded wheel for a profile grinding wheel.
 
Two available models, the Titan 1200G and 1500G, are designed for 1,200 and 1,500 mm workpiece diameters, respectively. Each machine features a single, universal dressing tool for on-machine dressing of both threaded and profile grinding wheels to eliminate change-over time.
 
During production of individual parts via pure profile grinding, a dual-flank, twist-free grinding option can create asymmetrical tooth trace modifications in half the time as conventional single-flank grinding, the company says.
 
The machines are equipped with Siemens 840D CNCs and Gleason Windows-based Intelligent Dialogue software to simplify setup and operation. For example, a grinding technology database recommends and optimizes the production methodology for the Power Grind process before machining starts. This enables less-experienced operators to produce high-quality parts more productively, the company says.
