PCBN Inbseerts for Bearing Inner And Outer Ring

	Workpiece name: bearing inner and outer ring
	Workpiece material: bearing steel (hardness HRC58-62)
	Insert model：BTS2800 SNGN160816
	Cutting parameters :Vc120m/min         Fr0.4mm/r     ap0.5mm
	Processing method: dry cutting
Tool material	Tool life	Final failure form
Berlt BTS2800 material	6 pieces	normal abrasion
CBN insert of a certain brand	4 pieces	Rupture
Note: The inner and outer rings of hard car bearings use solid CBN inserts. Compared with other brands of CBN tools, the tool life of Berlt tools is increased by 50%, which greatly improves the cutting efficiency.

PCBN Inserts for Bearing Raceway

	Workpiece name: bearing raceway
	Workpiece material: 40GrMoTi (hardness HRC58-62)
	Insert model：BTS2800 RNMN0904
	Cutting parameters：Vc=130m/min，Fr=0.25mm/r，ap=0.5mm
	Processing method: dry cutting
Tool material	Tool life	Final failure form
Berlt BTS2800 material	10 pieces	normal abrasion
A foreign CBN insert	10 pieces	normal abrasion
Note: Bearing raceway processing uses solid CBN inserts. Compared with a foreign CBN tool, Berlt tools have the same life, good tool consistency and stability, and high cost performance.
