Title:
SHAPE-CONTROLLED FLEXIBLE POLISHING METHOD FOR MICROARRAY MOLD
Document Type and Number:
WIPO Patent Application WO/2024/045493
Kind Code:
A1
Abstract:
A shape-controlled flexible polishing method for a microarray mold. The following solution is used: a magnet is mounted below a microarray mold (3), so that a prepared magnetic abrasive is attached to the surface of the microarray mold (3) under the action of a magnetic field force to generate contact pressure; a tip-containing polishing tool (1) is mounted above the microarray mold (3), and the tip-containing polishing tool (1) has the capability of attracting the magnetic abrasive; the tip-containing polishing tool (1) rotates, and under the action of a magnetic force and a centrifugal force, the magnetic abrasive at the tip of the tip-containing polishing tool forms a spherical polishing head; or the following solution is used: a ball-end milling cutter (8) is mounted above the microarray mold (3) by using a shear thickening fluid (11); by means of high-speed rotation of the ball-end milling cutter (8), the shear thickening fluid (11) is driven to rotate and a relative shear motion is generated; and polishing is performed under the action of the shear thickening effect. The shape-controlled flexible polishing method for a microarray mold can be adapted to the curvature of feature points of microarray molds, achieve efficient polishing of microarray molds, ensure the original surface shape precision of microarray molds, and achieve high surface quality.
