Tungaloy Corp. has extended its TurnLine range of Mini T-CBN inserts to incorporate a BX470 insert grade. The line is capable of boring diameters as small as 4.5 mm with indexable inserts. The BX470 grade designation has been added to the Mini T-CBN line for the effective machining of sintered metals.
Produced from a micro-grain cBN, the new BX470 delivers the highest hardness levels of all Tungaloy T-CBN grades to date. When compared to competitor grades, the BX470 delivers prolonged tool life and performance with reduced corner wear, claims Tungaloy.
The new BX470 has been proven to reduce tooling costs by over 60 per cent, while reducing tool change times by an additional 50 per cent, according to Tungaloy.
To enhance surface finishes and accuracy of the BX470 insert grade, the new range of inserts works in harmony with Tungaloy’s established â€˜StreamJetBar Mini’ line. The boring bars are available with a steel or carbide shank and right or left hand designations. The boring bars with through coolant facility are available for an array of insert designations and geometries.
