Jan 01, 2015 Grinding of sub-micron-grade WC-Co with good lubrication exhibits peculiar ‘size effect’ behavior more similar to brittle materials. Higher wheel speeds can be detrimental if the coolant velocity is not also increased. Grinding WC-Co at low aggressiveness Additionally, researchers have found that some materials exhibit dramatically changed physical properties when they are reduced to nanoparticles. For example, organic pigments, when processed to sub-micron sizes, offer greater color strength than those produced by conventional grinding to one or two microns. Sep 13, 2010 This high circulation rate results in a uniform dispersion, narrow particle-size distribution and faster grinding. There are two types of high circulation mills — one uses 3–10-mm media to process material down to sizes of a few microns, the other uses 0.1-2-mm media to achieve sub-micron and nano-size products. MEDIA SELECTION Holding tolerances on diameter size and cylindricity to the sub-micron level with Ultra-Precision Centerless Grinding we work closely with engineers who require a much higher level of precision for many of their high-tech parts. We use only new CNC grinding equipment because today’s tolerances require today’s technology. Feed materials as large as 300 microns can be reduced to sub-micron sizes. In the high energy configuration, feed materials as large as twelve inch agglomerates have been successfully milled and solid particles of a half inch are being reduced to a d50 of less than 5 microns. Sub-Micron Precision Grinding Capabilities At Camcraft. Just like clockwork. As time passes, higher demands are placed on all engine components— and to be more precise, fuel injection technology is where engine manufacturers routinely look to make bigger and better gains in efficiency and reduced emissions performance. May 12, 2011 Feed materials as large as 300 microns can be reduced to sub-micron sizes. In the high-energy configuration, feed materials as large as 12-in. agglomerates have been successfully milled and solid particles of a half inch are being reduced to a d50 of less than 5 microns. Sweco, Florence, KY 859-727-5116 sweco. Bulk Container Crusher/Feeder If your application needs reduction whether it is 6-inch to sub-micron size, choose from Prater’s superior fine grinders, air classifying mills, hammer mills, and lump breakers to meet all of your industrial processing needs. We have been designing, manufacturing and creating innovative solutions for large and small customers all over the world. For the finest grinding of materials to sub-micron sizes, Jet Milling is the more appropriate. In a Jet Mill, material is circulated around a circular or oval chamber at very high velocity under the influence of a compressed gas or steam. Size reduction is achieved purely through the attrition of one particle against another or the impact of Dec 01, 2000 Rough grinding operations require abrasive grain sizes in the range 36# to 46# mesh size in order to achieve a surface roughness of between 0.7 and 1.6 μm R a. Finishing operations usually produce a surface roughness of between 0.4 and 0.8 μm R a,and therefore, require a finer abrasive grinding size to achieve this (60# to 80# mesh size).
