SECO Germany encountered a real challenge in one of their key customers: a 660mm, 770mm deep hole in the stator housing, made of GG-30 (Seco material group 14), with intermittent cutting, Unequal amount. 
Seco CBN inserts are used in the GG30 material. The boring tool is connected by a bridge, which is equipped with a fine boring block and a counterweight, and then extended by the GRAFLEX module connection to a length to diameter ratio of 870/90 (almost 10 Times!). The bridge is mounted on a spindle that can be telescoped on a horizontal machine. The customer uses the CCMT09T304-F1 TK2000 insert with a processing speed of 100m/min, f=0, 21 mm/rev, 48 rpm, Vf=10 mm/mn, L=770x6 mm (ie 4620 mm). As a result, production efficiency is significantly affected by the SOOQ.cn copyright, and the tool trembles from time to time. Using the CBN insert CCGW09T304S-01020-LF-CBN200, the cutting parameters are VC=630 m/min, 300 rpm, f=0, 16 mm/rev, Vf=50 mm/min, L=770x6 mm (ie 4620 mm. ), tool life 92.40 minutes. Processing time has been reduced from 8 hours to less than 2 hours (92, 40 min)! The annual cost savings are 100,000 €!
CBN performs very well in the fineness of GG30 materials, even for long overhangs, interrupted cutting and uneven margins.
