The core advantage of this product lies in its unique SG abrasive,known for its high toughness and self-sharpening nature.Unlike conventional abrasives,SG grains fracture microscopically under grinding pressure,continually exposing new sharp cutting edges instead of releasing the entire grain.This results in excellent form retention,slow wear,and stable grinding performance over long periods,reducing the frequency of dressing.It perfectly combines high material removal rates with good surface finish,drastically improving efficiency in mass production and lowering overall costs.Its superior wear resistance makes it excel in machining various alloy steels,cast iron,and heat-resistant alloys.
This product is designed primarily for surface grinders.Common outer diameters range from 250mm to 500mm,with thicknesses from 25mm to 75mm.The bore is typically 76.2mm or 127mm.The abrasive composition is Ceramic Aluminum Oxide,sometimes blended with regular aluminum oxide.Grit sizes commonly used are 46#or 54#for efficient cutting.Hardness grades are mostly M to P(medium-hard to hard)to support its long-life characteristic.The bond is a high-performance vitrified bond.The wheel structure is dense,with a typically low porosity number.The maximum safe peripheral speed can reach 80 m/s,meeting the demands of modern high-speed grinders.It is often supplied with a steel flange for secure mounting.
Primarily used for high-volume surface grinding operations demanding high efficiency and long life.Common in automated production lines in the automotive,bearing,and hydraulic component industries for machining surfaces of parts like engine connecting rods,piston rings,bearing races,and valve blocks.It is also suitable for efficient roughing and semi-finishing of large workpieces on CNC surface grinders.Despite a higher initial investment,its exceptional service life and high metal removal rate offer unparalleled cost-effectiveness in scaling production.
