Applications in the area of cylindrical tools aim to increase cutting parameters and reduce friction and operating temperatures.
To extend the service life of the tool, Lafer offers a full package that covers de-coating, sharpening, cutting edge preparation, coating and post-coating treatments for application in the traditional areas of chip removal on milling cutters, drills, taps and reamers.
Increasing cutting parameters while reducing machining time and tool change time allows production costs to be cut.
Milling, the main chip removal process, requires analysing the working conditions and type of material to be treated in order to carefully select the most suitable coating to increase cutting parameters and minimise any internal stress. Lafer’s solutions make it possible to significantly improve wear resistance, thus protecting the rake faces from chip sliding.
The milling process can be divided into roughing – in which the coating provides a thermal barrier to protect the tool – and finishing – in which special attention is paid to preserving the cutting edge to ensure a better quality finish of the machined part
The main aims during deep hole drilling operations are to remove the chips quickly from the hole and to resist high temperatures. The requirements to be met by applying coatings vary depending on the material to be machined.
Lafer’s solutions for deep hole drilling tools enable friction to be reduced and improve chip evacuation from the drill flutes. The utmost attention is also paid to pre-finishing and post-finishing operations, making it possible to achieve smooth cutting edges, maximise chip evacuation and optimise the coated drill.
In the area of tapping , Lafer offers excellent solutions for both thread cutting and thread forming.
In thread cutting, the most important parameters are cutting edge hardness and smoothness to prevent chips from sticking. The low friction coefficient of the coated tool requires lower torque for the tapping operation.
In thread forming, good wear resistance and high compression resistance are key to preventing the plastic deformation of the material from damaging the cutting edge of the tap, which is protected by a wear-resistant coating.
