Models made in synthetic fibre and abrasive nappe colligated with resin, in two types of abrasives: Aluminium oxide (A) in red/maroon colour, and silicon carbide (S) in black/greyish colour.
The 08 model is made up of sheets of abrasive fibre set radially around a rigid core.
They can be used dry or lubricated with polishing paste or refrigerants.
In general, its main applications are glazed finishes or decorative grainings, light honing and trimming works, as well as preparation and cleaning of surfaces; type (A) is used for steels and stainless steels and type (S) for plastics, wood, ceramics and non-ferric materials, even though their indistinct use is possible, giving different finishes depending on the type of abrasive used.

Treatments E60 and E71 increase noticeably the performance as well as the hardness.

One of the applications of these products is the treatment of printed circuits:
Cleaning and preparation before the copper coating, treatment of the copper surface or de-rusting and elimination of burrs produced in drills. It is range 11.

>Printed circuit flap

GENERIC REFERENCE  11

Roller manufactured with sheets of abrasive fibre attached radially to a rigid tube, with J1 special chemical treatment.

Used in the printed circuit industry in its different work stages.

Impregnations: J1 (exclusive to this model)

External measurements: from 600 to 770 mm

Internal measurements: 50 mm

It can be presented with a conicity at 45º in the axis, which allows for a better settlement and centering.

With lateral rabbets to prevent the formation of ribs at the ends.


>Mixed flaps

GENERIC REFERENCE   09

Manufactured in the same way as the 08 model, alternating sheets of abrasive cloth (abrasive fabric) between the abrasive fabric sheets.
It combines the smoothing process with the uniformity of the glazing of abrasive fibre, allowing for decorative smoothing works and the smoothing of small burrs.

There are several combinations of abrasive cloth and fibre, we will usually have between 2 and 5 abrasive cloths per 1 or 2 sheets of abrasive fibre.

Possibility of special combinations for special works.

Standard measurements:

External:    165     : 200  :  250  :  290  :  340  :  390 :
Internal:   6/25/35 :   76  :    55  :   150 :  200  :  250 :
Width:  From 18 mm to 1400 mm
For widths over 300 mm, the roller is supplied balanced.
