Milling & Boring in St Louis, MO

Milling and boring are pivotal techniques in the world of metalworking, enabling professionals to shape, drill, and create designs with precision and efficiency. These methods, facilitated by vertical milling and boring machines, play a vital role in industries ranging from manufacturing to aerospace. In this article, we will delve into the fundamentals of vertical milling and boring as they pertain to metal work, address common questions, and explore the diverse applications that they serve.

Understanding Milling & Boring

Milling and boring involve the use of specialized machines equipped with rotary cutters to remove material from a workpiece, creating precise cuts and holes. These machines operate on a horizontal axis, allowing for versatile and accurate machining of various metal components. Horizontal milling allows blocks the be milled square on all 6 sides and well as the ability to create holes in the material if necessary.

Frequently Asked Questions About Milling & Boring Applications

  1. What types of metals can be processed using vertical milling and boring?

Milling and boring can be applied to a wide range of metals, including steel, aluminum, brass, copper, and alloys. The choice of tools and machine settings depends on the specific metal and the machining requirements.
