First, the metal substrate is cut down to 50 μm in diameter using WEDG, then, the micro-diamonds with 0-2 μm grain is "plated" on the surface of the substrate by composite electroforming, thereby becoming a multilayer micro-grinding tool. The thickness of the electroformed layer is controlled to within 25 μm.

The research deals with the development of micro compound tool consisting of a micro flat drill as a drilling part and a micro electroplated diamond grinding part for finishing.

Mechanical grinding is an efficient material removal process, however, for machining engineering ceramics, tool wear and cracks limit the development of grinding. In electrochemical discharge compound grinding, material is softened by spark discharge before being removed by grinding, so the problems of tool wear and cracking can be mitigated.

Tool wear in micro-manufacturing process is of paramount importance to meet stringent design requirements of workpiece in a cost-effective manner. In present work, tool wear in micro-rotary ultrasonic machining (μ-RUM) has been investigated for Ø300-μm peck drilling operation. Two sets of experiments have been conducted using electroplated hollow diamond tool and borosilicate glass as ...

Grinding and polishing of cutting tools, optical instruments, and other high-finish workpieces. It is also suitable for special-shaped workpieces made of the above-mentioned materials that are difficult to process with a grinding wheel tool. How to use diamond paste. Grinding paste is a type of surface finishing.

Micropencil grinding tools (MPGTs) are micromachining tools that use superabrasives like diamond and cubic boron nitride (cBN) grits to manufacture complex microstructures in a broad range of hard and brittle materials. MPGTs suffer from a rather low tool life, when compared to other more established microprocessing methods.
