Machining is a critical component of manufacturing in our society. But what happens when you take machining to a much smaller level? Micro machining has also become incredibly useful in the manufacturing world. Let’s take a look at some frequently asked questions about this precision machining technique.

Why Is Micro Machining Important?

Micro machining is important for a number of different reasons. The most notable of them being that micro machining offers a foolproof method for the single process machining of smaller parts. This means that milling and turning can be performed on the same machine, all thanks to micro machining tooling. As a result of this innovation, it’s possible for manufacturers to have much shorter lead times and to machine new parts in a more efficient manner. In most cases, even larger parts can be machined using micro machining tools and techniques for greater manufacturing efficiency.

Are There Different Types of Micro Machining Processes?

The short answer is yes. There are a few different kinds of micro machining processes, and some of the most commonly used include:

  • Electric Discharge Micro Machining (EDMM)
  • Laser Beam Micro Machining (LBMM)
  • Electron Beam Micro Machining (EBMM)

While there are many types of micro machining processes, these three are typically used the most often. These techniques allow for greater efficiency and precision when machining parts of all shapes and sizes. These types of micro machining are suitable for a variety of different materials, as well. Micro machining may be necessary for small watch parts, various conductive materials, and more.

How Has Microo Machining Evolved?

Micro machining is a technique that was actually invented in the late 1990s in response to a growing demand for more intricate parts. This demand came mostly from the medical and semiconductor sectors. Through trial and error, a need for higher-speed spindles, precision reamers, single-point tools, and other machines that were capable of producing small, intricate parts arose. Now, a variety of tools exist to help get the job done. When manufacturers contribute more than $2 trillion to the economy, it’s not hard to see why such innovation was required.

Micro machining is a process that dictates how much of the more intricate machinery of the word operates. It pays to understand this manufacturing technique.
