This process involves creating accurate and straight bores to restore the alignment of the equipment, improving its performance and reliability.


DGC AFRICA's Line Boring service is carried out by skilled technicians using state-of-the-art equipment and tools, ensuring that the work is performed to the highest quality standards. The company's team of experienced technicians has the knowledge and expertise to handle the most complex line boring projects, ensuring that the equipment is restored to its original specifications.


Our Line Boring service includes:


  • Repairing or refurbishing bores and bearing locations in heavy equipment, machinery, and engines

  • Creating accurate and straight bores to restore the alignment of the equipment

  • Improving performance and reliability


The Line Boring process begins by measuring the bore's diameter and checking for any misalignment or damage. Once the measurements are recorded, the technician sets up the boring equipment and starts the cutting process. The cutting head is advanced into the bore and removes material until the bore reaches the desired diameter. The cutting head is then withdrawn, and the next bore is bored in a similar manner. The process is repeated until all the bores are cut to the required diameter and alignment.


Industries that benefit from DGC AFRICA's Line Boring service include:




Line boring is a specialized machining process used to repair and restore cylindrical bores, typically in large equipment and machinery.


The process involves enlarging or repairing existing bores using a boring bar that is inserted into the bore and rotated to cut material.
