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 endmill gave a tool life of 400 components which  resulted in lot of down time and a higher tool consumption. 

Solution

The Titainox and Superalloys range represents the innovative proposal for machining  stainless steels, titanium and superalloys, capable of achieving cutting parameters that are much  higher than those offered by high-end items. The innovative superior-quality cutting edge, the specific  rake angle surface treatment, together with Silmax 4S superfinishing process allow to combine an  extraordinary finish (surface roughness below 1 micron), while maintaining the maximum cutting  performance.  

Result

The total tool life has increased by 4x thanks to the the PVD Balzers Latuma ® coating  currently represents the best proposal for machining titanium and stainless steels. The total cost  saving per annum is 3.50L approx.
