Railway line

The HEULE solution automates the chamfering of both sides of the bores for stable and reliable process. Due to mechanical deburring, it is no longer necessary to purchase new machines.

Customer application

A customer from India required a solution for drilling bores to connect 260 metres of rails. For reasons of safety, they were required to modify the rail. The front and back chamfers were being applied manually, which has not proven to be an ideal method.
