Cotton abrasive disks
Composition and Use
The entire cotton abrasive disks are made with whole cotton sheets joined by a seam around the central hole, or entirely sewn. This article can be made from different types of cottons, with impregnation or natural, depending on the consistency of the material to be processed. The disk in whole cotton is particularly suitable in the roughing-out and polishing processes, both in the manual working and in the automatic one, depending on the size of the disk. Usually the large disks are mounted on automatic robots, while smaller ones are installed on manual machines. Depending on the softness of the cotton, these cotton abrasive disks are used for the polishing or finishing processes. The materials on which such article is used with more frequency are brass, the zinc alloy, aluminum and stainless steel.
Available sizes
From Ø 150 to Ø 1000
Disk types
White, Dora, Rio and made of Flannel
Type of structure: quilted, whole

Sisal abrasive disks
Composition and Use
Sisal abrasive disks are made with sisal, a textile fiber of rough plant origin. Thanks to this characteristic, this fiber is used in the roughing-out process of metals. Sisal abrasive disks present a hard abrasion suitable to impress in a decisive manner on the workpiece. In fact, this type of disk is mounted, during the operations of polishing of metals, on the machines suitable for the roughing-out of the workpiece, that means in the first steps of the finishing process of the raw materials. Sisal abrasive disks are also available in sisal-cotton, in order to increase its abrasive force on the workpiece to be processed.
Available sizes
From Ø 200 to Ø 1000
Disk types
Sisal or Sisal-Cotton, Quilted, SP

Corrugated abrasive disks
Composition and Use
This particular type of disk can be composed of both several types of cutting and polishing cotton, and sisal/cotton, for roughing out process. There is also the possibility to resinate sisal/cotton disks with various colors , to make even more rigid and incisive the corrugated disk.
The cloth is folded in such a way to get regular corrugation. The main use of the corrugated disks, consists in mounting on a shaft more elements so as to obtain a cylinder with a compact surface, since the convexities and concavities of the disks fit together perfectly.
The working surfaces on which the corrugated disks are particularly suitable are the aluminum and brass; They are also used with excellent results in the polishing of the pots.
Available sizes
From Ø 300 to Ø 500
Disk types
Corrugated cotton RIO disks – Corrugated cotton DORA disks – Corrugated Sisal-Cotton disks – Corrugated abrasive cloth disks

Fold Up abrasive disks
Composition and Use
Fold up disks can be composed of both cotton, for the finishing processes and sisal/ cotton, for roughing out processes.
The fold up disk is used in immersion processes of shaped articles and mounted on rotary tables machines which work either continuously or by jerky shots.
The particularity of this disk is precisely the pleating, that means how the cotton sheets are overlapping so as to form elastic folds, which allow a perfect balancing of the wheel. The main strength of the fold up wheel is the ability of penetration into the workpiece, since the elasticity of the folds, created by the cotton, allows to wrap partially the workpiece to be polished and accordingly, to allow a perfect finishing of the object.
Available sizes
From Ø 200 to Ø 1000
Disk types
Fold Up cotton RIO disks – Fold Up Cotton DORA disks – Fold Up Sisal-Cotton disks – Fold Up abrasive cloth disks

Ventilated abrasive disks
Composition and Use
Ventilated abrasive disk can be composed of both sisal, sisal/cotton, for roughing out processes and several types of cotton for the finishing processes of the surfaces.
The ventilated disk is used both in manual workings that in those robotized.
Its main feature is precisely ventilation, that means how sisal or cotton are disposed so as to avoid overheating of the disk; this occurs through the air passage in the external part of the disk. Consequently, the ventilation allows the perfecting of the finishing process of the metal, without causing any damage to the product under treatment.
The ventilated disk is available in several types of cotton and colors, which are distinguished according to the hardness.
Available sizes
From Ø 100 to Ø 690
Disk types
Ventilated cotton RIO disks – Ventilated Cotton DORA disks – Ventilated Sisal disks – Ventilated Sisal-Cotton disks – Ventilated abrasive cloth disks
