![]() ![]() Here layers of excess material are removed from a solid 3-D blank to obtain final product. Both machining and grinding processes follow the basic principle of subtractive manufacturing approach.Similarities between machining and grinding Important similarities and differences between machining and grinding are discussed below. ![]() Moreover, only a limited types of abrasive is used, like alumina, silica, diamond, etc. Although grinding wheel has defined specification, the abrasive grits have no specific geometry. These abrasives actually remove material from work surface in the form of micro-chips to provide a smooth surface. On the other hand, grinding utilizes a circular wheel made of sharp, tiny and random shaped abrasive grits strongly held on suitable bonding medium. Cutter material also varies widely – from age old carbon steel to modern day’s materials like cBN and diamond. ![]() Such processes offer low material removal rate (MRR) but high accuracy, close tolerance and better finish.Ĭonventional machining (also known as metal cutting) processes utilize a sharp-edged wedge shaped cutting tool to compress and shear off material from workpiece. are classified as surface finishing processes. In order to improve surface quality and dimensional accuracy, separate finishing operations can be carried out. ![]() Such processes are mainly applied for bulk removal (stock removal) of material with high material removal rate. Achieving high dimensional accuracy, close tolerance and surface finish are usually not possible by conventional machining processes like turning, milling, shaping, planing, drilling, etc. Seco Tools - Cutting Tools solutions Seco Tools is one of the world’s largest providers of comprehensive metal cutting solutions for milling, stationary tools, holemaking and tooling systems.Primary objective of any subtractive manufacturing process is to remove layer by layer material from a solid 3-D blank to achieve desired shape, size and finish. ![]()
