Read OnFig.3 Grinding ratio of different CBN grinding wheel on grinding different materials. 3 As can be seen from Fig.3a: 3.1 The grinding ratio of 6 kinds of CBN grains for cast iron HT250 materials is high, the grinding ratio is 147.9-213.9, of which CBN-B1500 is the highest and CBN850 is the second. For the same abrasive, the grinding ratio of ...
Read OnThe CBN shape grinding wheel. 2. Design of the axial profile of the CBN wheel base body. The profile of the grinding wheel used to generate a spur gear is that of the tooth space of the ground gear. In the case of a helical gear, the contact trace between the grinding wheel and the ground gear should be a spatial curve.

Read OnCBN wheels are important for grinding HSS. This is because it's a better material for sharpening and for durability, one of the best available. Diamond is harder than CBN, but over time many people have discovered that diamond is not a suitable abrasive grain and isn't a good choice when grinding on high speed dry wheels.

Read On5-Axis CBN Grinding. Hi-Tek has many 5-Axis 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. Hi-Tek's central coolant systems provide ultra-filtered, temperature controlled grinding oil at constant delivery pressure for ...
Read OnIn order to improve the machining accuracy and production efficiency of face gear, a generating grinding method for face gear using cubic boron nitride (CBN) wheel is studied in this paper. The mathematical model of the CBN wheel profile is derived based on face gear grinding principle and theory of gearing. Taking the demands of machine motion during face gear …
Read OnMolylub. SynGrind CBN. SHC-POE base oils. 9.2. CBN grinding wheels with vitrified bonds (VIT- CBN) It is known that the G ratio of CBN grinding is lower when water based coolants are applied, leading to higher tool costs. The chemical decomposition of CBN is frequently associated with its interaction with high temperature steam in grinding.

Read OnIn the grinding process, the linear speed of CBN grinding wheel can reach 100m/s, so as to ensure better grinding efficiency. However, due to the high linear velocity, there is a strong friction and cutting heat, which will affect the quality of bearing processing. In bearing grinding process, therefore, should be coolant injection of CBN grinding wheel, it can not only to the …
Read OnThe 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-removal rates.
Read OnCBN, cubic boron nitride, is a man-made material that rivals the strength of diamond. The boron atoms replace the carbon atoms that make up the structure of diamonds. By replacing the carbon atoms with boron, CBN wheels are able to grind ferrous materials with ease. CBN is ideally suited for any hardened steels due to minimal heat up.
Read OnAnother 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. ... Using five-axis CNC, the wheels can produce shapes previously ...

Read Onof cBN is almost two orders of mag-nitude greater than that of aluminum oxide (Ref. 2). Further work by GE suggests that in grinding with aluminum oxide, about 63% of the heat generated goes into the work piece, while with cBN grinding only 4% goes into the work piece. The study at GE suggests cBN grinding of carburized parts and hardened parts
