Precision On-Site Line Boring for Mining & Heavy Equipment

Worn bores, pivot points and pin housings can lead to excessive movement, accelerated wear and costly equipment downtime. U & L Engineering provides precision on-site line boring services that restore critical components to their correct tolerances, helping extend equipment life while reducing transport costs and unnecessary downtime.

On-Site Repairs, Faster Turnaround

Our mobile line boring equipment allows us to complete precision machining directly at your site, minimising downtime and getting equipment back into operation sooner.

Restore Original Tolerances

Accurate machining and alignment restore worn bores to specification, improving equipment performance, reliability and component life.

Precision Repairs Without Removing the Machine

Transporting heavy equipment for workshop repairs isn’t always practical. Our mobile line boring service brings precision machining directly to your site, restoring worn bores, pivot points and structural components while reducing downtime, transport costs and production delays. Every repair is completed with careful measurement, accurate alignment and quality workmanship.
