Broaching square holes
Horn initially enhanced the product range back in 2019 by introducing internally cooled tool holders. 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 units and for turret broaching. The targeted cooling reduces tool wear, in turn increasing the 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 cutting deep grooves. What’s more, the stronger flushing action improves chip removal, reducing the risk of chip build-up.
The ability to carry out broaching on CNC machines offers the user several advantages. Grooves can be cut in a workpiece in a single clamping without having to reclamp the workpiece. This broaching process allows geometries of any kind to be produced, from gears, keyways, squares and helical grooves right through to curved grooves. It represents a cost-effective alternative to conventional broaching because it can be used on virtually any CNC lathe.back to overview
