What size of line boring machine should I choose?
With a wide range of line boring machines available, it's essential to consider the specific types of jobs you'll be performing. A single machine may not accurately cover all diameters, so careful selection tailored to your job requirements is crucial.
What boring bar length should I specify?
Selecting the appropriate boring bar length is job-dependent. While numerous bar lengths are available, it's important to note that for small diameter boring bars, increased length can lead to a higher risk of sagging.
What are the lead times for line boring machine?
Lead times vary based on machine size and stock availability. Planning ahead is essential, as it can take several weeks from payment receipt to machine delivery. Each machine package is custom-built from numerous available options, necessitating a thoughtful approach.
Can DIG-DOG supply a machine in my area?
Absolutely! Our portable boring machines are exported worldwide, ensuring global availability.
What maintenance is needed?
Proper care ensures years of trouble-free operation from your line boring machine, delivering consistent and accurate results. Routine maintenance includes simple cleaning, debris removal, and regular oiling.
