Single TBM Cutter Rings TBM Twin Center High Speed Disc Cutters 17"
18" 19" 20" Ready Stock
The hob parts "bearing" made by the company adopt imported original
products such as TIMKEN of US, SKF of Sweden and NTN of Japan and
the sealing elements adopt UME of US, which ensures that all kinds
of cutting tools have the performance features of high precision,
high bearing, strong reliability and high life.
Using self - developed high quality materials, the knife ring
produced by our company leads the domestic counterparts and
achieves international standards. Its HRC is 56 to 58 after a
special process treatment, and the impact energy value detected by
National Steel Yannake Testing Center is up to 40 J
(internationally recognized), and the impact power resistance of domestic products of the same trade generally 24 to 30J.
Therefore, our cutters have the characteristics of good impact ,
high hardness, good wear resistance and long service life. Our
company will choose different types of cutter rings for different
strata to meet the needs of customers.

Forgings are made by the closed die method as Germany. Subsequent
processing consisting of two machining steps and four heat
treatment steps are completed in China.The steel manufacturing
processes are designed to keep impurities to the lowest.Melting in
an Electric Arc Furnace is followed by vacuum degassing. Ingot
molds are filled from the bottom with the liquid steel shrouded in
argon gas. Exceptionally clean steel ensures high resistance to
fatigue, resulting in longer cutter disc life
