Vitrified CBN Wheels
Saili have been producing vitrified CBN wheels for more than
ten years and have found some way to pro duce
wheels in top quality and competitive prices. Saili's products
have been used for various application in different fields,
such as, bearing, compressor, automobile, aerospace and general
industries.
Using Saili vitrified CBN wheels means the increase in dressing
cycles with improved surface integrity, better dimensional
tolerance and greatly reduced costs.
Saili vitrified CBN wheels have been sold to the markets
both in home and abroad. Some wheels in famous brand in the
world, such as, Winter, Mitsui, Asasi, Noritake, Tyrolite
have been gradually replaced by Saili's products
Vitrified CBN wheels are most suitable for the materials:
Cast Iron
Bearing Steels
High Speed Steels.
Heat Resistant Alloys (i.e. nickel alloys)
Vitrified CBN wheels are widely used for the application:
INTERNAL GRINDING, such as, joints, Bearings, Injector
nozzles and Gearbox, etc.
SURFACE GRINDING, such as, Creep feed grinding, Slot grinding,
etc.
TOOL GRINDING, such as, Drills, End Mills, Taps, Broaches,
etc.
CYLINDRICAL GRINDING, such as, Bearings, Camshaft, Crankshaft,
shafts, Spindles, etc.
Vitrified CBN wheels offer the following advantages:
Increasing the ability in remaining invariant in the process
of grinding;
Decreasing the time of truing and dressing as well as wheels'
changing.
Escaping work pieces from burnt.
