CBN tools and tool compared to conventional materials What are the different places

cbn at high temperature to 2000 ℃ was still with excellent red hardness .
cbn is a hardness second only to diamond superhard cutting tool materials ,

usually in the processing of the material hardness greater than 48HRC works

best when ( machining soft materials cbn wear out quickly ) . cbn at high

temperature to 2000 ℃ was still with excellent red hardness . Although cbn

more brittle than cemented carbide , and the thermal and chemical stability

than the ceramic , but it has a higher than ceramic cutting tools impact

strength and crack resistance , and low rigidity of the machine is also able

to cut hard metals. In addition, custom- cbn proper power tool can withstand

rough cutting load, intermittent cutting blows and finishing the required

high temperature and abrasion resistance . Appropriate for the specified

customization processes including machine and fixture rigidity , edge

grinding large enough to prevent microscopic peeling , and the tool base body

is a high content of grade cbn . cbn grade high content of these specified

processes are required, because they have high speed under heavy load

conditions edge machining requirements of high thermal resistance and

toughness and for severe intermittent cutting . These properties make this

material is used as a tool material grade roughing of hardened steel and

pearlitic gray cast iron .
low content of material grades cbn cbn content than the more brittle grades ,

but they are used when machining hardened ferrous better performance . They

have a lower thermal conductivity and a relatively higher withstand high-

speed cutting and the negative rake angle  General purpose blade of the compressive strength of the

heat generated . Higher cutting zone temperature can help soften the

workpiece material and chip breaking , while negative rake angle can enhance

the tool cutting edge stability , improve tool life and allows depth of cut

is less than 0.25mm . Because the tool can Edge 2000 Pads  cbn surface finish of better than

0.4μm and maintain concentricity of ± 0.012mm , dry car hardened workpiece

is usually an attractive alternative to dirty grinding the cooled solution

strengthening . Although cbn is a hard turning and high-speed milling

particularly fond of tool material, but  polyethylene oxide the ceramic and cbn have an amazing

range of applications overlap , and therefore it is necessary to use the cost

- benefit analysis to determine who can get the best results .
