In the field of high-end precision gear manufacturing, the performance of processing equipment directly determines product accuracy and production efficiency. With growing demand for large, high-precision gears in industries such as wind power, marine, aerospace, and heavy machinery, combined grinding technology is becoming a key focus for gear manufacturers worldwide. As a factory dedicated to producing premium precision gears, Gearseiko continuously monitors cutting-edge processing technologies. Below is a technical overview of several representative combined gear grinding machines currently available on the market.

Gleason’s TITAN series of large form grinding machines, including the 1200G and 1500G models, accommodate workpiece diameters of up to 1200 mm and 1500 mm respectively. The most outstanding feature of this series is its ability to perform both pure form grinding and worm‑wheel generating grinding on a single platform. Using Gleason’s exclusive POWER GRIND process, worm‑wheel grinding is applied for high‑efficiency roughing, followed by form grinding for finishing, which can reduce total grinding time by up to 50%.

Key technical parameters for the TITAN 1200G include: centre distance (between grinding wheel centre and table centre) of 100–950 mm; maximum axial stroke standard 700 mm (optional 1000 mm or 1300 mm); rapid traverse rates of 12 m/min in axial (optional 20 m/min) and 12 m/min in radial. The worktable has a diameter of 800 mm, a centre hole diameter of 250 mm, and a table height of 1100 mm. For worm‑wheel generating grinding, the maximum module is 14 mm; work spindle power is 24 kW (90 N·m) with a maximum speed of 5500 rpm; maximum worm wheel outside diameter is 350 mm and maximum width 160 mm. For form grinding, the maximum grinding tooth depth is 80 mm, maximum wheel width 100 mm, spindle power and speed remain the same, maximum wheel outside diameter is 450 mm, minimum dressable diameter 175 mm, and wheel bore 127 mm. The machine is equipped with an automatic tool changer (2–4 grinding wheels) and can use two wheels simultaneously for high‑efficiency roughing. Notably, a patented universal dresser allows both worm and form wheels to be dressed on the machine with a single dressing tool, significantly reducing setup time and tooling costs. Machine weight (without cooling system) is 40,000 kg, and overall dimensions are 8070 mm × 5020 mm × 4000 mm.

The TITAN 1500G extends the centre distance to 100–1100 mm while all other specifications remain consistent with the 1200G. Additionally, the Gleason 300TWG high‑speed CNC worm‑wheel grinding machine also offers form grinding capability, providing more flexible options for small‑ to medium‑sized gear production.

For batch production of small‑ to medium‑sized workpieces up to 500 mm in diameter, Höfler’s VIPER 500 series offers an exceptionally flexible solution. The series is available in three configurations: form grinding (standard), K‑version (for special workpieces and multi‑wheel grinding technology), and W‑version (worm‑wheel grinding). The combination model (KW) integrates both functions.

The VIPER 500W model is particularly remarkable – it can perform both form grinding and worm‑wheel generating grinding on a single machine, with extremely fast tool changeover. Switching from generating to form grinding takes less than 5 minutes of auxiliary time; changing from external to internal gear grinding takes less than 15 minutes. To change the grinding function, only the grinding wheel, flange, and dressing roller need to be replaced. The machine can also be equipped with different internal grinding arms, enabling flexible conversion between external and internal gear processing.

Key specifications of the VIPER 500W include: workpiece diameter up to 500 mm; module range 0.5–13 mm; grinding head swivel angle range –45° to +180°; maximum grinding wheel diameter 350–221 mm; maximum wheel width 150 mm; and maximum rapid traverse speed 20 m/min. The highly dynamic axes with acceleration of 5 m/s² ensure excellent productivity. The machine adopts dry grinding technology, eliminating the need for an oil pump station and significantly reducing operating costs and maintenance workload.

As a professional factory in the field of high‑end precision gears, Gearseiko fully understands the decisive impact of processing equipment on product quality. From the POWER GRIND high‑efficiency process represented by the Gleason TITAN series to the “one‑machine‑multiple‑functions” philosophy embodied by the Höfler VIPER 500W, world‑leading combined grinding technologies are redefining the boundaries of efficiency and accuracy in gear manufacturing.
