Targeted cooling reduces wear on the tool, increasing its life and improving the quality of the workpiece surface. Due to the internal coolant supply, lowering of the temperature is assured even when taking deep cuts, says Horn. In addition, the stronger flushing action improves chip removal, reducing the risk of accumulation.
The ability to carry out broaching on a lathe offers several user advantages. Firstly, it represents a cost-effective alternative to conventional broaching and can be deployed on virtually any turning centre. Machining can be performed in a single clamping without having to re-fixture the workpiece. Additionally, the broaching process allows geometries of any type to be produced, from gears, keyways and helical cuts, through to curved features.
