Line Boring
On-site Line Boring for all types of earthmoving machinery
Precision Engineering & Welding are experts in workshop and on-site line boring – boring internal diameters (ID) and ID welding. We can ID bore, weld and accurately machine worn components back to original specifications, or at times, bore to fit a sleeve or fit a hardened bush.
We have a vast array of experience in earthmoving, mining, agricultural machinery and cranes, to name a few. We operate a fully hydraulic mobile line boring and internal welding machine which has been designed and manufactured within our own workshop.
We have the capability of welding and boring from 40mm diameter to 500mm diameter.
This combined with our own full machine shop facilities, such as lathes and milling machines etc, ensures the best possible equipment available is used for your repairs, and that your downtime or manufacturing process is minimal.
The machinery we regularly service:
- Backhoes
- Dozers
- Scrapers
- Tractors
- Excavators
- Cranes

Our on-site Line Boring service offers a fully automated line borer, operated by experience and skilled staff to get the job done right the first time.
