Challenge: The Ti-6Al-4V alloy is an α–β titanium alloy that exhibits high strength, low density, and good corrosion resistance. It is one of the most commonly used titanium alloys. The joining of C/C and TiB whisker (TiBw) reinforced Ti-6Al-4V composite by brazing is more effective by using a brazing material consisting of Cu–Ni alloy and TiB2 than one consisting of only the Cu–Ni alloy. The shear joint strength is 56% higher for the former. The TiB2 particles in the brazing material react with Ti, which diffuses from the TiBw/Ti-6Al-4V composite, resulting in the formation of TiB whiskers in the brazing layer. The in situ synthesized TiB whiskers are uniformly distributed in the joint and provide reinforcement and decreased residual thermal stress.
Due to the machining complexity the current insert gave a tool life of 400 components which resulted in lot of down time and a higher tool consumption.
Solution: Secure insert clamping and strong insert design of Duo Just-Cut prevents insert breakage when machining at high rates. Tungaloy(JXPG20R20F-15SH725)
Double-ended parting inserts has a very sharp cutting edge with 0.8mm width insert with pressed-in 3D Chip breakers Provides reduced material waste and low cutting forces during parting-off operations – Robust insert design withstands repeating bar feeder pressures, allowing the toolholder to be used for workpiece positioning.
Result: The total tool life has increased by 4x and thus resulting in reduction of tools per annum. The total cost saving per annum is 4.00L approx.
