Abstract
A nanoparticle colloid jet machining (short for NCJM) system was designed combined with computer control technology, that can be used for ultra-smooth surface machining of small curvature radius aspherical components and free surface components. Ultra-smooth surface machining experiments were done upon a high-purity quartz glass substrate with an aspheric surface. Surface profilometer was utilized to measure the surface profiles of workpiece before and after being polished by NCJM. The results indicated that the NCJM can realize material removal of nanometer level by computer control. The maximum material removal of 900 nm was achieved at axial direction of aspheric workpiece. Atomic force microscopy results showed that the surface roughness of the component's outline cross-section curve was reduced from R a 2.860 nm to R a 0.460 nm. NCJM is suitable for polishing free surface components and can realize controllable material removal.
