Diamond grinding wheels for carbide rolls are specially engineered for high-precision and high-efficiency grinding of tungsten carbide roll rings used in wire rod mills, bar mills, and rolling production lines.
Due to the extreme hardness and wear resistance of carbide (up to 10,000 HV), diamond abrasive is the most effective solution, delivering superior cutting performance, dimensional accuracy, and surface quality compared to conventional abrasives .
Moresuperhard offers a full range of:
Electroplated diamond wheels
Metal bond diamond wheels
Resin bond diamond wheels
to meet different grinding stages including rough grinding, semi-finishing, and precision groove grinding.
Tungsten carbide roll rings grinding
Grooved roll profile grinding (groove forming & redressing)
Cylindrical grinding of roll outer diameter
HVOF / thermal spray coated rolls
High-speed steel (HSS) roll grinding
Steel & wire rod rolling mills
Non-ferrous metal processing
Tube & pipe manufacturing
High Precision Profile Replication
Accurately copies complex groove geometries
Achieves precision up to 0.01 mm tolerance
Excellent profile retention during full wheel life
Superior Grinding Efficiency
High material removal rate
