Overview
The Gleason P 90 WM is a CNC gear cutting machine for producing cylindrical gears using the power skiving process. Gleason is the world leader in gear manufacturing technology, and the P 90 WM represents their latest generation of power skiving machines for high-volume production of spur and helical gears.
The P 90 WM handles workpieces up to 90 mm in diameter. Power skiving combines the speed of hobbing with the flexibility of shaping, enabling efficient production of internal and external gears, including gears that are difficult or impossible to hob due to interference with shoulders or adjacent gear meshes.
The machine features a direct-drive workpiece spindle capable of high-speed synchronization with the tool spindle. The tool spindle provides speeds up to 5,000 rpm. All axes use direct-drive motors for fast, precise motion without backlash.
The P 90 WM runs on Siemens 840D sl with Gleason-specific gear machining software. Automatic tool measurement and compensation are included. Machine weight is approximately 6,000 kg.
Power skiving on the P 90 WM can be 5-10x faster than gear shaping and handles both internal and external gears with the same machine. The P 90 WM competes with power skiving machines from Liebherr, MAG, and Pittler.
New machines price $400,000-$600,000. Used trade $200,000-$400,000.

Strengths & Limitations
Strengths
- Power skiving is 5-10x faster than gear shaping for many applications
- Handles both internal and external gears on the same machine
- Direct-drive axes eliminate backlash for precise gear tooth geometry
- Gleason gear software includes automatic tool compensation
- Gleason is the undisputed world leader in gear manufacturing technology
- Produces gears that cannot be hobbed due to clearance issues
Limitations
- Limited to 90 mm workpiece diameter
- Power skiving requires specialized carbide skiving tools that are expensive
- $400,000+ price point is significant even for gear manufacturers
- Gleason service contracts can be expensive
- Operators need specific power skiving process knowledge

Frequently Asked Questions
01
New $400,000-$600,000. Used $200,000-$400,000.
02
A continuous cutting process where a tool resembling a shaper cutter rotates synchronously with the workpiece. It combines hobbing speed with shaping flexibility.
03
Yes. Power skiving excels at internal gears that cannot be hobbed due to tool clearance issues.
04
90 mm workpiece diameter.
05
Siemens 840D sl with Gleason-specific gear machining software and automatic tool compensation.
