Spline rolling : Technology

ESCOFIER has created and developed several technologies for the spline rolling. According to the work piece to be rolled, we define the best process adapted to your specific needs.

Incremental® spline rolling

• Fixed centreline distance (T1). Possible adjustment during production changeover
• Rolling cycle = 1 single tool rotation. The work piece is driven by the tools

Advantages and characteristics

• Extremely short rolling time (Most of the time less than 4sec.)
• No waste of productivity since there is no back motion of the rolling tools
• Fp < 30 µm
• Max. Module : 1,5

Syncroll® spline rolling

• Variable centreline distance (T1)
• Rolling cycle = as many tool rotations as required (limitless). The work piece is driven by an CNC motor synchronized with the tool rotation.

Advantages and characteristics

• Cycle time is generally between 6 and 12 sec.
• Fp < 20 µm
• Max. Module: 1,5
• Rolling of long splines using through-feed system
• Rolling of helical splines
• Rolling of hollow parts
• Rolling of parts with a high number of teeth
