0113. Most of the CBN grinding wheel substrate is made of metal, and when the CBN grinding wheel is grinding, most of the heat energy will be transmitted
Cubic Boron Nitride (cBN) is a superabrasive material that has traditionally been used to grind materials, such as steels and nickel alloys. Though not as hard as diamond (4500kg/mm2 vs 9000 kg/mm2, respectively) cBN has the benefit of not being as chemically reactive with ferritebased and nickel alloys and as such, can often outperform
Cubic boron nitride (CBN) is a highly durable synthetic abrasive mineral, second only to diamond in hardness. This durability makes it ideal for grinding hardened steel and superalloys materials commonly used in the manufacturing of powertrain, bearing and turbine components. 3M offers a wide range of CBN abrasive products, including
Abrasive grinding wheels. This marking system is used to describe the wheel composition as to type of abrasive, grain size, grade, structure and bond type. CBN and diamond wheels. The same standardization is applicable to CBN and diamond wheels. Wheel markings are a combination of letters and numbers. Grinding wheel shapes and
Another method of CBN grinding uses a single layer of CBN grain bonded to a precision steel wheel core. The bonding method usually is nickel plating. Wheel cores can be replated up to 10 times, resulting in a lower abrasive cost per part than experienced with vitrified wheels. Of course, plated CBN wheels cannot be dressed resulting in a
And wheel grade as a function of grinding ratio G and surface roughness R a as with Aluminum Oxide and CBN Abrasive Wheels, Transactions of the ASME, 117(1995) 160–168p.
Cubic boron nitride, henceforth abbreviated to CBN, is a synthetic crystalline material that is second only to diamond in terms of hardness. It is structurally analogous to diamond too, with a complex cubic/sphalerite structure composed of interpenetrating facecentred cubic lattices. Essentially, CBN abrasive grains are
The revised coolant application setup on the right side was based around coherentjet nozzle tubes. As can be seen in the photo, one 0.187″ (5mm) and two 0.125″ (3mm) diam nozzles were fitted to supply the center and each corner of the plated CBN wheel, and two 0.187″ (5mm) diam nozzles were fitted to supply the vitrified CBN wheel.
5Axis CBN Grinding. HiTek has many 5Axis CBN Grinders for generating radial features on highly complex nickel / cobalt turbine components. Parts as large as 36" x 36" x 36" can be processed on these grinders. Cubic Boron Nitride (CBN) grinding wheels are perfect for machining processes that call for intricate shapes and features.
Features. Diamond and CBN grinding wheels have high quality synthetic diamond / CBN (cubic Boron Nitride) abrasive material for ensuring high precision while cutting hard materials. These grinding / cutting wheels deliver high material removal rates and can easily cut difficult to grind steel parts. These grinding wheels are wear resistant and

A more efficient way to grind superalloys involves the use of cubic boron nitride (CBN) wheels. CBN is the secondhardest material [5] after diamond. CBN can be synthesized to produce a variety of crystal shapes, colors, morphologies and physical properties which, in turn, can tailor grinding performance. Superalloy grinding is routinely

The recommended wheel speeds during dry grinding is in the range of 3000 to 4500 SFPM (15 to 23 m/s). The higher wheel speeds may cause burning of the tool edges. In wet grinding, wheel speeds in the range of 5000 to 6500 SFPM (25 to 33 m/s) provide excellent results. In general, the higher speeds improve both wheel life and metal
The grinding wheels' size was 140 x 13 x 50.8 (mm), the wheels being designated WA46K8V, GC60J8V and CBN100P75V. For all experiments, the wheel speed, table speed, and downfeed were in the range Vs = 6501320 m/min, Vw = 25 m/min and d = 5 15 ~tm, re spectively.

CBN wheels are used most often on hardened ferrous materials and can be found in machines like tool and cutter grinders, camshaft grinders and gear grinders. Compared with Al 2 O 3 wheels, CBN wheels run cooler, last longer and can function at higher speeds. Diamond is used to grind carbides, glass and other extremely hard
