Line Boring

Pin bores and pivot points are susceptible to wear, especially on heavy and industrial equipment.  HTR is able to repair these worn out bores using our specialized equipment.   With the use of our automated bore welder, the bores are built up with weld until they are slightly undersized.  Then a boring bar set up is used to machine the bores back to spec.  

HTR several different boring bars and machines available to use, based on the bore diameter being reconditioned.  Currently we are able to handle bore up to 24" diameter, and as small as 1.5".

 

We are also able to machine and repair bore faces that are truly perpendicular to the bore with the use of a variable feed facing head.  Internal snap ring or seal grooves can also be cut.
