Development of company of Kyocera industry ceramics gives the bit of pottery and porcelain that can replace CBN, machine the aperture inside material spare parts steel, alloy steel, cast-ironly, hard with the carbon that at high speed hardness of boring of thick, essence is as high as HRC45. The hardness that it compares diamond and CBN data not only performance of tall, wear-resisting is good, and have very good chemical stability, can be so below the condition of high cutting rate, big feed and cutting deepness (namely below condition of tall cutting temperature) undertake machining, for example, ＝ of optional choose V 76. The cutting speed of Min of ／ of 2 ～ 762m (the cutting rate that compares hard alloy razor blade rises 50 ％ ～ 60 ％ , the cutting rate that compares cermet razor blade rises 20 ％ ～ 25 ％ ) . And very good treatment surface surface roughness can be obtained below dry cutting condition. CNC Milling
