Semi-flexible abrasive tools are a variety of products also known as coated abrasives. These include the popular flap discs, semi-flexible grinding discs, mounted flap wheels, fiber discs and CBS, as well as nonwoven discs. Semi-flexibles are abrasive tools with a wide range of applications, from operations to remove large allowances, machining welds, grinding to size, deburring, cleaning to smoothing and polishing.

Different resin bonds and different backing materials

In the case of semi-flexible tools, the bond acts as a link between the individual abrasive grains, as well as the grain and the background. Bonding technology is more complex (multi-stage) than is the case with classic resin or ceramic bonded grinding wheels, sometimes with various types of composites.
The background itself also comes in several solutions - paper in different weights, canvases, fibers, polyester and others - which is elementary in terms of its strength and flexibility. Thus, depending on the version of the organic bond used (adhesives or synthetic thermosetting resins), as well as the backing material, different performance of abrasive tools can be expected.

ANDRE's semi-flexible tools (coated), thanks to our many years of experience, are of high quality. Our team of technology specialists responds to the individual needs of end users by manufacturing abrasive tools with strictly designed physical and mechanical parameters dedicated to specific grinding operations.

Example of a semi-flexible abrasive tool design

Applications of semi-flexible abrasive tools:


  • Used in grinding operations including different level of removal to finishing operations, various types of maintenance and repair.
  • Used for grinding a wide variety of materials of steel, aluminum, wood, marble, granite, terrazzo, concrete, ceramic, glass, cast iron and more.

Features of semi-flexible abrasive tools:

wide range of applications thanks to original appropriately selected, grain compositions and various backing materials

flexibility in relation to the materials to be machined; tools "adapt" in shape to the surface to be ground

the desired machining effect in the form of an evenly smoothed surface

high safety

low level of noise emission

convenient for the operator - a lot of pressure do not required

FLAP DISCS

Features of flap discs:
• deburring and surface finishing in a single operation
• do not cause scratches on the workpiece
• easily adapt to the workpiece shape
• easier corner processing than with other tools
• quiet operation
• direct mounting on the grinder - no pads.

DISCS WITH PROFILED ABRASIVE COATING

Features of discs with profiled abrasive coating:
• long life
• resistant to "loading", no burns
• easy to adapt to the workpiece shape
• convenient for the operator - a lot of pressure do not required
• require shims (plastic or rubber) when mounting to the grinder.

CBS DISCS

Features of CBS abrasive discs:
• deburring and surface finishing in one operation
• do not cause scratches on the workpiece
• cool grinding • quiet operation
• they are an alternative to steel brushes
• direct mounting on the grinder- no pads.

MOUNTED FLAP WHEELS

Features of mounted flap wheels:
• precise, uniform surface finishing
• easily adaptable to the workpiece, even more complex shapes
• easier processing of hard-to-reach places
• work in great comfort
• wear evenly due to good balance
• direct clamping thanks to the pin.

FIBER DISCS

Features of fiber discs:
• high working efficiency
• long life
• cool grinding
• quiet operation
• require the use of backup pad when mounting to the grinder.

SOFT NON-WOVEN DISCS

Features of non-woven discs:
• deburring and surface finishing in one operation
• adapting to the specific shape of the surface to be worked on
• high efficiency in polishing work
• direct mounting on the grinder - no pads.

Abrasives

Grain compositions dedicated to different operations

At ANDRE ABRASIVE ARTICLES, the production of semi-flexible abrasive tools uses modern abrasives, selected for the task at hand, both in terms of removing the allowance and finishing the surface to be ground. The most common is brown aluminium oxide for standard applications, while zirconia and ceramic grain are used where much higher performance is required. Some of the semi-flexible tools dedicated to specific applications are also produced based on silicon carbide.

95A - Brown fused alumina

ZrA - Zirconium alumina

X (Ca) - Ceramic electro-corundum (blue)

99C - Green silicon carbide

98C- Black silicon carbide

Abrasive tools by ANDRE ABRASIVE ARTICLES are safe.

ANDRE gradually improves its technological process to offer abrasive tools with increasingly better usability and a high safety factor in accordance with the applicable standards. Membership in organizations of leading abrasive tool manufacturers and regular certification fully confirm that.
