Biffignandi Spa – Precision Polishing, in order to increase and complete own products portfolio for its customers, began the production of Scalloped Rolls Microfinishing Film.
The scalloped rolls have edges with a waved customized design according the customer request or developed on worked piece dimension combined with the superfinishing machine setting.
We offer consultancy and technical support to develop the best profile for every application/worked piece.
The scalloped rolls dimensions are defined as: roll Width (W), Scallop Length (SL) and Scallop Depth (SD).
The rolls are wounded on 1” or 3” plastic core with ASO (Abrasive Side Out) or ASI (Abrasive Side In) specifications.
Scalloped Rolls Microfinishing Film represent the higher quality alternative to coated abrasives cloth jagged/waved rolls thanks to:
High performance and high torque crankshafts have journals with radius (and without deep rolling fillets) in order to improve the structural strength of critical brake points of the component.
The superfinishing process made with scalloped rolls will allow the microabrasive film to follow and finish gently the journal profile keeping the requested tolerances, while straight edges rolls could affect or damage the geometry of the radius.
Scalloped rolls can be applied to other superfinishing process where the worked pieces have angled or rounded profiles that cannot be handled with traditional straight edges rolls.
