Expansion of the N117 Broaching System

Horn presents a new and enhanced version of an existing product in the form of its N117 internally cooled broaching system.

The new tool holders allow coolant to flow through the insert seat as well as to the side of it for optimised cooling during broaching. In addition, the geometries have been adapted for use in broaching machines and for turret broaching.

The targeted cooling reduces tool wear, in turn increasing tool life and improving the quality of the workpiece surface. Thanks to the internal coolant supply, cooling is ensured in the contact zone even when taking deep cuts. What’s more, the stronger flushing action improves chip removal, reducing the risk of chip build-up.

The ability to carry out broaching on a CNC lathe offers the user several advantages. Machining can be carried out in a single clamping without having to reclamp the workpiece.

This broaching process allows geometries of any kind to be produced, from gears, keyways and helical cuts right through to curved cuts. It represents a cost-effective alternative to conventional broaching because it can be used on virtually any CNC lathe.
