Tips for Top Boring Performance
Poor quality in the boring process can adversely affect the quality of the finished product and cause future safety issues. To produce the proper bore, you need to understand the factors involved to avoid any issues that could occur during the process. Here are three of the most common boring issues you need to avoid assuring quality.
Maintain True Bore Depth
Today’s modular tooling systems provide multiple combinations of boring tools to achieve the correct usage and maximum rigidity. Keep in mind, that when you select boring tools, you need to consider the true bore depth and the extra reach required. In a project that requires extra tool length, begin with a broader base size, and then gradually reduce the diameter to meet specifications.
Correct Speeds and Feeds are Critical
Choosing the right speeds and feeds is essential for the efficient operation of tools. This part of the boring process is critical in free-cutting conditions. Depending on these conditions, the boring bar is typically run at high speeds and moderate feed rates.
Avoid Unstable Parts
Unstable parts can have a negative effect on boring process performance. The operator will need to fix any unstable parts, fixtures, or worn machine spindles to ensure a quality project. Generally, minor adjustments in cutting parameters and insert types can improve quality significantly. Pay close attention to the size and power of the machine center as they determine the cutting parameters. Remember, that roughing heads work differently when used with spindles of different sizes.
