This product leverages the high hardness,thermal stability,and wear resistance of CBN abrasive,offering advantages when grinding hard and tough steels.It exerts low grinding forces and generates minimal heat, preserving the workpiece's geometric accuracy and surface integrity,thus avoiding grinding burns and micro-cracks.The wheel wears very slowly and has excellent form retention,making it particularly suitable for automated production on CNC machines,ensuring remarkable consistency in batch part dimensions.Although the initial cost is high,its ultra-long service life and very low cost per ground part make it indispensable in high-end manufacturing.
This product is an electroplated or vitrified CBN wheel,typically used for internal grinding.The outer diameter range is relatively small,from 10mm to 50mm,with the thickness customized based on the workpiece groove width.The CBN abrasive layer is typically single-layer or a few millimeters thick,attached to a high-strength steel or aluminum core.Grit sizes range from 100#to 400#or finer for fine finishing.Since CBN itself is extremely hard,its"hardness grade"concept differs from conventional wheels and is determined more by the bond type and concentration.CBN concentration(an indicator of abrasive content)is a key parameter,commonly 100%or 150%.The maximum peripheral speed must be determined based on the core and bond type.
Primarily used in the automotive,aerospace,precision bearing,and mold&die industries.Typical applications include precision grinding of hardened gear bores,fuel injector holes,bearing races,and high-precision mold cavities on CNC grinders.It is the preferred solution for machining components with hardness above HRC 50,capable of achieving mirror-like finishes and micron-level dimensional tolerances,often replacing costly lapping and polishing processes.
