In chip removal processes, the main goal is to facilitate chip evacuation while avoiding thermal shocks as much as possible to increase the tool’s service life.
In this area, Lafer offers a coating and treatment solution that ensures a reduction in friction and operating temperatures as well as lubricant use to achieve the best quality of the finished part.
Turning is one of the heaviest and most challenging chip removal applications – being a continuous cutting operation, the cutting edge must withstand very high temperatures and stress.
It is therefore crucial for these coatings to be thick, reduce any internal stress and have a high oxidation temperature. Another key feature of coatings for turning is a compact structure that combines high toughness, hardness and wear resistance.
The milling process is generally comprised of two steps – roughing and finishing.
In the former, the tool must withstand high stress to remove the largest quantity of material in the shortest time possible. During finishing, the tool operates to remove a smaller volume of metal and obtain a finished product that is suitable in terms of dimensions, tolerances and surface finish.
