Have you ever heard the saying “the more things change the more they stay the same?” The same mantra applies in the machining industry.

The principles of machining remain much the same as it did in the Industrial Revolution – and even before. Today, we discuss how studying manufacturing history can help you utilize the technology of today. We became excellent at deep hole drilling straight holes with precision and accuracy by studying how Cannons were made in the 1700s.
