

Aluminium oxide Flap wheels are conformable to intricate shapes and contours, high quality aluminium oxide abrasive cloth, high working efficiency, stable grinding quality, no burning working-pieces, easily continuous operating.


Flap wheels are conformable to intricate shapes and contours Design to deliver a consistent finish with a uniform rate of cut, flap wheels wear away,continually exposing fresh abrasive.


aluminium oxide abrasive cloth substrate keep synchronous consumption. Good heat dissipation, do not burn work-piece.


Good brightness after grinding, can be used as one-time grinding, no need last procedure of polishing

The first is the protection problem, the protective cover is the main protective device of the polishing machine, its role is, when the flap wheel is damaged in the work, can effectively cover the impeller, to ensure the safety of personnel.
Secondly, the balance of the flap wheel is mainly caused by the manufacture and installation of hundreds of flaps of inaccurate, so that the center of gravity and rotary shaft do not coincide.The harm caused by the imbalance is mainly shown in two aspects, on the one hand, in the high speed rotation of the vane wheel, cause vibration, easy to cause the workpiece surface polyangular vibration marks, on the other hand, the unbalanced acceleration of the spindle vibration and bearing wear, serious will cause the vane wheel page rupture, even cause accidents.
Matching problem.The matching problem mainly refers to the installation problem of chuck and flaps. According to the standard requirements, the diameter of the chuck shall not be less than 1/3 of the diameter of the installed sand disc, and the corresponding provisions wear to the diameter larger than the chuck 10mm should be replaced with a new flap wheel.
