Flexible polishing mechanism for blade profile abrasive belt

The invention discloses a flexible polishing mechanism for a blade profile abrasive belt. The flexible polishing mechanism is fixed on a numerical control machine through an installing frame. The flexible polishing mechanism drives a polishing wheel to act along the direction of a stationary shaft for controlling the polishing force; and a rolling wheel is arranged on a base plate for supporting the abrasive belt, a tensioning cylinder enables the abrasive belt to generate a pretightening force on the rolling wheel, a drive wheel drives the abrasive belt to rotate at high speed on the rolling wheel for controlling a cylinder in the flexible polishing mechanism so that the polishing wheel can make an axial displacement action, i.e. a cutter acts through flexibility in the polishing process, thus blade profile deformation and damage caused by rigid shock are avoided. The line deflection of the abrasive belt, generated in the polishing process, is regulated through a deviation correcting mechanism. The flexible polishing mechanism has the advantages of simple structure and convenience for operation, and realizes an automatic polishing process of the blade profile, thus the polishing quality of the blade profile is increased and the working efficiency is increased.

Numerical control abrasive belt grinding machine with six-axis linkage

The invention discloses a numerical control abrasive belt grinding machine with six-axis linkage. An upright post component and a worktable are arranged on the grinding machine body in a sliding way, and the relative sliding between the two of the upright post component and the worktable and the grinding machine body respectively forms liner motion of X-axis direction and Y-axis direction; an A-axis component is arranged above the worktable and used for clamping a workpiece to rotate around the axial line thereof so as to form rotary motion of the A-axis; a cantilever on the upright post component is provided with a grinding seat which is connected with the upright post component through a box body in a sliding way so as to form liner motion of Z-axis direction; a turntable is arranged on the box body in a rotating way, and the relative rotation between the turntable and the box body forms rotary motion of B-axis direction; an abrasive belt machine is arranged inside the grinding seat, and the relative rotation between the abrasive belt machine and the grinding seat forms swivel motion of C-axis direction; and the grinding machine controls the motion of each axis direction by a numerical control system. The numerical control abrasive belt grinding machine can greatly enhance grinding efficiency, and can effectively improve the grinding precision and surface quality of the workpiece.

Single-step electromechanical mechanical polishing on Ni-P plated discs

Beginning with a smooth ground aluminum blank with a relatively thin layer of leveled Ni—P, circumferential electropolishing/texturing is carried out to achieve a smooth oriented surface. A conductive slurry is provided between the disc and a porous texturing tape which is in contact with a conducting plate or equivalent conductor. The disc serves as the anode, and the conducting plate as the cathode, while the slurry, being conductive, functions as an electrolyte. In the presence of current, a reverse electroplating occurs so that the Ni—P dissolves to form Ni2+, or nickel ions which are carried away by the conductive slurry. The conductive slurry further supports or carries therein abrasive material so that by moving the porous texturing tape past the disc surface, the texturing tape picks up the abrasive material in the slurry and simultaneously with the reverse electroplating, provides the desired mechanical abrasion to achieve texturing of the disc surface. The abrasive material comprises diamond particles. The circumferential electropolishing/texturing polish is achieved by spinning the disc while applying the mechanical-chemical action through the slurry system to the disc surface with electric current passing through the electrically conducting interface during processing.
