3-Way Motion - Key to Precision

• Bottom lap plate is fixed - providing a zero-runout base.
• Carriers orbit the center sun gear at controlled speeds.
• Top lap plate spins at twice the speed of the planet carrier orbit speed.
• Removes material from top & bottom of parts equally.
• Minimizes contact stresses on part edge and carrier teeth, which reduces "crashes" and edge chipping, and increases carrier, ring and center gear life. For very thin parts and high loads.
