PORTABLE LINE BORING MACHINE The DIG-DOG Portable Boring Machine is a revolutionary piece of portable processing equipment, meticulously developed for the on-site maintenance of construction machinery. This versatile machine excels at machining small pipe inner holes and concentric spacing holes, making it indispensable for the on-site upkeep of heavy-duty machinery like excavators, cranes, and loaders. By reducing the costs associated with equipment maintenance and significantly enhancing efficiency, this machine is a must-have for any construction project.
Main Application: This machine is perfect for machining revolving holes, articulated holes, and shaft pin holes on various engineering machinery structures post-repair welding. It also excels in installing hole sleeves after reaming. Additionally, it ensures the repair and processing of concentric holes, enabling one-time positioning processing of multiple holes on excavators, loaders, presses, cranes, and more, thereby ensuring the coaxial alignment of the holes.

What size of line boring machine should I choose?
With a variety of line boring machines available, choosing the right size depends on the specific jobs you'll be undertaking. No single machine can cover all diameters accurately, so consider your primary applications carefully.
What boring bar length should I specify?
Boring bars come in various lengths, and the best choice largely depends on your job requirements. Note that for smaller diameter boring bars, a longer length increases the risk of sagging.
What are the lead times for line boring machines?
Lead times vary by machine size and stock availability. It's wise to plan ahead, as it can take several weeks from payment receipt to machine arrival. Each machine package is custom-made from many available options, contributing to this timeframe.
Can DIG-DOG supply a machine in my area?
Absolutely, our portable boring machines are exported worldwide, ensuring you get the best machinery no matter where you are.
What maintenance is needed?
Properly maintained, the line boring machine delivers years of trouble-free use, consistently providing accurate results. Regular cleaning, debris removal, and oiling are generally all that's needed to keep it in top condition.
