Abrasive machining is a material removal process that uses abrasive particles to cut, grind, polish, or finish a workpiece. Unlike conventional cutting tools (e.g., drills or lathes), abrasive machining relies on hard, granular particles (such as silicon carbide, aluminum oxide, or diamond) to erode material through friction and micro-cutting. This process is particularly effective for hard, brittle, or heat-resistant materials that are difficult to machine using traditional methods.  
Key Types of Abrasive Machining Processes: 
1. Grinding – Uses a rotating abrasive wheel to remove material, achieving high precision and fine surface finishes.  
2. Honing – Employs abrasive stones to improve the geometric form and surface texture of cylindrical bores.  
3. Lapping & Polishing – Uses loose abrasives in a slurry to achieve ultra-smooth, flat surfaces (common in optics and semiconductors).  
4. Abrasive Jet Machining (AJM) – Blasts high-speed abrasive particles (e.g., garnet or aluminum oxide) to cut or etch hard materials.  
5. Abrasive Flow Machining (AFM) – Forces a viscous abrasive media through complex passages to deburr and polish internal surfaces.  
6. Ultrasonic Machining (USM) – Combines high-frequency vibrations with abrasive slurry to machine brittle materials like glass and ceramics.  
Advantages of Abrasive Machining:  Capable of machining extremely hard materials (e.g., tungsten carbide, ceramics).  Produces superior surface finishes (up to nanometer-level smoothness).  Suitable for precision tolerances in critical applications like aerospace and medical devices.  Abrasive machining is indispensable in industries requiring high precision, such as automotive, aerospace, and electronics manufacturing.
Abrasive Flow Machine Uses Diamond Fine Powder, Silicon Carbide Powder or other Abrasives Mixed Into Polymer Elastic as a soft medium .The abrasives flow up and down through the inner holesor over the machined surface to achieve surface polishing. Especially suitable for all kinds of mould and irregular shape tiny cavities.Abrasive flow is not only a device, but also a system engineering!It includes equipment, abrasives, tooling fixtures, and important detail design and experience, which are not only reflected in the final effect and efficiency, but also reflected in the long-term stable use, and can help customers save a lot of trial and error costs!
