Drills – cutting Mills – Reamers and the sharpening
Here we are again, remembering our first post concerning the need to avoid too much wear between a regrinding and the next one.
Now we need to look into two main tool types concerning metal processing and these are tools in Hard Integral Metal and tools in Braze welded carbide:
Today we will consider :
- HARD INTEGRAL METAL aka Carbide:
once worn this tool can no longer be used, it follows that the quality of hard metal, used to produce it, is just as important as the production technique.
Save on the hard metal quality is not a good idea it means at the end that you will have a tool that spoil more quickly, the same goes for the production technique.
The main working processes are with “wire” or with “diamond wheels” the latter and the compliance with tolerances increase your tool life and as a direct consequence it will INCREASE your production capability according to the tool profile of two, three times and even more than the one obtained with tools produced with another technique.
Try to control numerically how many pieces you produce with a tool produced with a wire technique and how many with a tool produced using diamond wheels, making the final sum
Production + number of tools required + new sharpening costs
you will see that the last while costing more will result the cheapest solution.
The same applies to the:
- BRAZE WELDED HM: This tool has the advantage that it can be RENEWED i.e. the HM plates after several regrinds as described above can be replaced with new plates while maintaining the body. Thus reducing the cost that you should face to buy a new tool.
Now I hope you got more and more interested in our long posts and I am looking forward to meet you again with the next part of this brief handbook.
