What size of line boring machine should I choose?
Selecting the right size line boring machine depends on your specific job requirements. There are various sizes available, and no single machine can cover all diameters accurately. Careful consideration of the types of jobs you will be performing is essential for making the right choice.What boring bar length should I specify?
Choosing the appropriate bar length depends largely on your job requirements. It is important to note that for small diameter boring bars, a longer bar increases the risk of sagging. Therefore, balance your needs with practical limitations to ensure optimal performance.What are the lead times for line boring machine?
Lead times for line boring machines vary based on the machine size and stock availability. Planning ahead is crucial, as it can take several weeks from payment receipt to machine delivery. Each machine package is custom-made from numerous options, adding to the lead time.Can DIG-DOG supply a machine in my area?
Yes, our portable boring machines are exported worldwide, ensuring that a machine can be supplied to your area.What maintenance is needed?
With proper care, the line boring machine will provide years of reliable service, delivering precise and consistent results. Maintenance primarily involves simple tasks such as cleaning, debris removal, and oiling to keep the machine in optimal condition.
