World premiere: Titan® 1500G
Up to 50% increase in productivity at maximum quality levels achieved by combining threaded wheel and profile grinding.
Gear manufacturers expect modern gear-cutting machines to be able to produce gears with considerably increased productivity while maintaining the highest levels of precision. In the Titan 1500G grinding machine, Gleason is now launching a highly innovative machine which addresses both of these issues.
- From making an individual part to large-scale production - always the right solution.
From making individual parts, which requires the greatest possible flexibility at maximum efficiency, the performance of the Titan 1500G can be increased in stages right up to fully-automated large-scale production of gears and adapted to suit users’ individual requirements.- Pure profile grinder option (profile depth up to 100 mm)
- Combined threaded wheel and profile grinder (profile depth up to 35 mm)
- Automatic tool change
- Tooling-up table for tooling up during primary production time
- Automatic workpiece change
- Advanced profile grinding
The unique patented option of dual-flank twist-free grinding halves finishing time! A highly dynamic machine concept furthermore reduces non-productive downtime to an absolute minimum. The time required for setting up the workpiece is also reduced to an absolute minimum with the machine recording and automatically compensating for misalignments during the chucking process. Time-consuming alignment is eliminated. - Significant reduction in primary production time for workpieces up to module 14
The combination of threaded wheel and profile grinding allows significant reductions in grinding time of up to 50%. The customary high quality of gears generated by profile grinding, for example, can be achieved on a workpiece with module 14 and a tip diameter of approx. 1500 mm with a 55% increase in productivity. Only the use of threaded wheel grinding combined with profile grinding – a unique feature worldwide – can achieve such convincing results. - Dresser - no tooling-up required
The optional addition of a dresser (patent pending) for the combination of threaded wheel and profile grinding allows dressing for both grinding processes using only one dressing tool. No need to change tools. - Automatic tool changer
- Grinding Wheel change is fully automatic.
- A coarse roughing wheel and a fine finishing wheel enable previously impossible results to be achieved for a short grinding time combined with highest surface quality, both for the combination of threaded wheel and profile grinding and for pure profile grinding.
- No interference between tool and workpiece in the entire diameter range. This means both processes can be combined without reservation up to the maximum workpiece diameter of the machine.
- External Set-up table (option)
Set-up table allows the next workpiece to be set-up in workholding equipment in parallel with primary production. Zero-point clamping systems ensure maximum precision and repeat accuracy at all times. This significantly reduces machine idle time. - Automatic workpiece changer (option)
Actual workpiece change is very quick and independent of workpiece weight. A zero-point clamping system ensures high reproducibility of workpiece position at all times. - Adjustable coolant nozzles
Coolant nozzles are automatically adjusted to the decreasing tool diameter resulting from dressing, guaranteeing optimum delivery of coolant straight to the grinding process at all times resulting in thermally safe grinding at maximum productivity. - Dialog program
Depending on the desired end-result regarding grinding time, quality and/or gear modifications, the dialog program generates a proposed optimum process combination for roughing and finishing . The technical cut segmentation is fully automatic and can be accepted or also modified by the user. The time required for centering and measuring has been significantly reduced by means of modern integrated programming technology, while maintaining the same high quality and reliability. The time required for centering and pitch measurement could be reduced by as much as 50%, tooth trace and profile can be measured up to 25% faster.

Multi-disc grinding
Up to 40% increase in productivity
World first: dressable profile grinding in several workpiece slots at once.
To enable our customers to derive significant productivity benefits on tried and tested Gleason-Pfauter profile grinding machines as well as on the Titan machine on diameters up to 6,000 mm, multi-disc grinding at EMO is setting another milestone in the hard finishing of large-module gearsup to module 16.
Multi-disc grinding facilitates:
- Productivity benefits of up to 40% (depending on workpiece characteristics).
- Greater process reliability as a consequence of more favorable contact conditions between the grinding wheel and the workpiece flank.
- Superior results in terms of productivity and surface quality from the use of grinding wheels with different grains for roughing and finishing.
World premiere: Phoenix® 280C
Up to 35% increase in productivity at maximum quality level.
Bevel gear manufacturers expect modern gear-cutting machines to be able to produce bevel gears of the required precision with considerably increased productivity. The new Phoenix® 280C from Gleason’s is a significant step forwardin gear-cutting technology.
- Productivity
Substantial increase in productivity is effected by integrated part loading system which allow gears to be changed in a maximum of 5 seconds and pinions in a maximum of 7 seconds. Processes such as deburring and spinning-off in wet machining are performed during primary production to eliminate non-productive time. - Chamfering and Deburring
This process is carried out on the optional loading station. Heel and toe can be chamfered and deburred – all during primary production time. - Quick change tooling
Particular attention has been paid to changeover time which has been minimized using quick-change equipment for both cutter bodies and workholding equipment tools. The Phoenix® 280C features the same excellent ergonomic characteristics as its predecessor. - Machine features
While the new machine retains the extremely rigid monolithic column design, there is a new approach to the frame, which is cast from an advanced polymer composite material. This provides significant benefits in terms of thermal stability and damping in particular. Chip evacuation has also been optimized, preventing cutting chip build-up in the work chamber. The perfect machine for dry cutting. - Software
The Phoenix® 280C has an innovative new user interface suitable for both Fanuc and Siemens control systems. Machine operation is very simple and the machine can be operated after a short introduction. The operating instructions and videos can be called up to support any troubleshooting required. - Integrated measurement
Tooth flank form and pitch are measured in the machine to help reduce long waiting times in the measuring room. Our customers expect a preliminary test to be performed on the first part before the machine is released for production and this is the next step towards fully-automatic closed-loop production.

Spheric® Power Honing Machine 150SPH
Up to 100% increase in productivity
At this year’s EMO, Gleason is presenting the new 150SPH Power Honing Machine with leading-edge Spheric® Honing for finishing hardened spur and helical gears. Its directly-driven honing head with speeds of up to 3,000 rpm, linear drives and up to 10,000 rpm at the workpiece enable this machine to produce automotive gears in half the time previously required. A wide variety of honing tool systems can be used on this machine to satisfy the various requirements of different component geometries, resulting in a significant increase in tool life. Honing of gears is used to achieve low-noise surfaces. Furthermore, honing is also used for machining workpieces which can’t be ground due to interferences.
The latest version of the Spheric® Honing software runs on the Siemens 840D control. In addition to simple, graphically-aided data input, the software also provides process data calculation. In combination with easy-change fixtures and tools, the system could not be any more user-friendly. The integrated loading system reduces loading times and downtimes by up to 70%, and it provides a link to the customer’s own automation concepts. On the basis of many years’ experience in honing, Gleason-Hurth bundles its experience in machine tool engineering, tool design and technology for maximum productivity and quality.
