Ceramic Inserts
AC02 Type
¡¡¡¡It has a higher hardness and wear resistance,and
good anti-welding and high temperature properties,and suitable
for semi-finishing and finishing of hard cast iron and heat
resistant steel,hardened steel,and quenched and tempered steel
as well as roughing of high temperature alloy steel.
SNS01/SNS02 Type
¡¡¡¡The ceramic has higher chipping and thermal
shock-resistance,high strength,and good toughness and chemical
stability.It is suitable for semi-finishing and finishing
of diverse chilled cast iron ,alloy cast iron,and high speed
steel,and chilled steel,etc.
