Boring Operation Challenges
The process of boring is the perfect application to drill accurate and precise holes in various materials. While boring offers several benefits to machinists, it can also present challenges. As with any manufacturing technique, it is best to understand the challenges a process could involve before beginning a project. This blog will identify and discuss several of the main boring operational challenges.
Generally, improper measuring results in the highest number of low-quality products in manufacturing. It is critical that the machinist conducts measurements and then rechecks them to ensure that incorrect measurements do not damage the part or fail to meet specifications.
Machining errors in the boring process create dimensional issues in the shape, location of holes, or finish of the product. These errors can be caused by setting the boring parameters incorrectly, the cutter rod having a too high length/diameter ratio, improper allowance adjustment, or using the wrong cutters for the workpiece material.
Worn or Damaged Tools
In the boring process, friction occurs between the boring tool and the material. This friction causes tool wear and damage that can reduce performance and negatively affect the precision of the holes. In addition, using a flawed tool can require more surface treatments and post-processing operations.
Cutting lines or scales found on the surface of a part is usually a result of a mishandled feed rate during the boring process. This part of the boring operation is essential in producing quality surface finishes. Practiced machinists often start a boring project with a feed rate of 0.1 to 0.2 mm per revolution.
