Long-lasting and efficient
CBN wheels
1. CBN EARESTBOY, Vitrified bond CBN wheel, is a highly valued diamond grinding wheel for PCD/PCBN materials. CBN EARNESTBOY is developed based on our EARNESTBOY. CBN EARNESTBOY is non-porous. However, the formation of adequate chip pockets, because of moderate bond wear, allows chips excrete. This new feature permits continuous grinding with long interval dressing. As a result, wheel condition is readily achieved.
2. CBN EARNESTBOY contains chemically bonded abrasive grits. Therefore, the increased grit retention prevents wasteful grain and pulls out for better grinding ratio and lower costs. Furthermore, the need to correct machining dimensions is reduced by the minimized wheel wear. The Vitrified bond has higher rigidity than resin bond, proving high-accuracy machining.
Feature
Eliminate thermal damage
Due to the excellent cutting ability, thermal damage to metal workpiece is eliminated. When a CBN wheel is used for grinding, compressive stress remains on the workpiece surface. Both strength and wear resistance are improved, in comparison to grinding with a conventional wheel.
Easy automation
Since the minimization of changed in wheel shape reduces the need for dressing, automation is easier than when using a conventional grinding wheel.
High-accuracy grinding possible
High-accuracy grinding is possible because there are minimized wheel wear and high rigidity.
Tough materials are machinable
Even difficult-to-cut ferrous materials that cannot be readily grounded by diamond or conventional wheels, can be grounded by CBN wheels.
Cost reduction per piece
The high grinding ratio reduces the wheel cost per workpiece. Savings are also produced by less frequent dressing/truing. Rejects and regrinding are both reduced due to high-accuracy.
