The tips are just burning out!

We get many people coming to us with this problem.

Often, there are many factors that may cause the cutting edge to fail. 
The causes could be:

➡ Microscopic chipping of the cutting edges. There are numerous reasons for this and may include: Surface speed is too low. Feed-rate may be incorrect; Too small or too high are both possible factors. 
➡ Chipbreaker geometry is always designed to suit a small range- often there’s a sweet-spot where conditions are perfect. 
➡ The cutting insert hard metal (usually tungsten carbide) may be too hard and not sufficiently tough. 
➡ The cutting ‘edge condition’ may be too sharp with insufficient strength. 
➡ ‘Chip hammering’ or chip / swarf trapping. 
➡ Incorrect centre height - this is critical especially on smaller components. 
➡ There may be a problem with cutting edge build up (often called built-up-edge).

All of these points are a good start but if you’re still unsure and would like to get in contact with us to discuss further please don’t hesitate to get in touch.
