Tool wear and machining performance of cBN–TiN coated ...
PCBN is the dominant tool material for hard turning applications due to its high hardness, high wear resistance, and high thermal stability. However, the inflexibility of fabricating PCBN inserts with complex tool geometries and the prohibitive cost of PCBN inserts are some of the concerns in furthering the implementation of CBN based materials for hard turning.Ask For Price
Effect on cutting force in turning hardened tool steels ...
Cubic boron nitride (CBN) or polycrystalline (PCBN) inserts are widely used as cutting tool material in such high-speed machining of hardened tool steels—due to high hardness, high abrasive wear resistance, and chemical stability at high temperature. Cutting forces and feed forces were determined in the numerical simulations.Ask For Price
Investigation of wear resistance of coated PcBN turning ...
The machine has a DC motor of 25 kW with a maximum rotational speed of 5000 rpm and a maximum torque of 380 Nm. The maximum machining diameter x length is 630 mm × 1250 mm. For the turning tests, the hardened steel AISI 52100 was used. This material is frequently used as bearing steel, due to the high hardness and wear resistance.Ask For Price

Recommendations on inserts for hard turning
Jun 22, 2017· Almost all hard turning is done with CBN inserts, usually CBN tipped inserts. A CNGA will come with 1,2 or 4 usable corners. Now the grade and edge prep is application dependent but they are a bit versatile. I'm sure many here will have favorite flavors. Chip control is a problem as chipbreakers cut into CBN are expensive.Ask For Price
