PFERD Policap abrasive cap with cylindrical shape and pointed cone end have a seamless design for smooth operation, and the entire surface of the abrasive cap can be used. The high degree of fitting accuracy between the components ensures that the abrasive caps remain securely attached to the holder during use. Advantages; Because of slots, the holder expands during use, guaranteeing that the abrasive cap is firmly clamped in place; Good dimensional stability and excellent fine grinding thanks to a special manufacturing process; Easy to change-out abrasive caps. Application examples; Fine grinding in tool and mould construction; Finishing on turbine blades after repair; Feather edging of radii at transitions after milling frames in aircraft construction; Fine grinding of hard-to-reach areas and bores; Levelling of transitions in fitting and pump construction. Recommendations for use; Abrasive caps can be mounted and removed by turning them slightly to the right; Abrasive caps are easier to replace when the holder is mounted on the tool drive.
