Escofier has developed multiple patented processes for spline rolling. Based on the desired characteristics of the final part, we specify the right process for your needs.
The Incrémental® process
- Fixed centre distance (T1). Adjustment possible when changing series
- Rolling cycle = 1 rotation of the tools. Part rotation is induced by the tools
Advantages and Characteristics
- Extremely short rolling time (in general < 4sec.)
- No waiting for the return of tools to home position
- Fp < 30 µm
- Maximum module 1.5
The Syncroll® Process
- Variable centre distance (T1)
- Rolling cycle = As many rotations as necessary. Driven workpiece holder induces synchronised tool rotation
Advantages and Characteristics
- Rolling time is generally between 6 and 12 seconds.
- Fp < 20 µm
- Maximum module 1.5
- Long spline manufacture using forced through-feed rolling
- Rolling of helical splines
- Rolling of hollow parts
- Rolling of splines with a large number of teeth
Applications
Spline rolling has many applications in a number of fields: automotive, aerospace, construction, medical, tools, household appliances, etc.
