High precision machining is a process that produces metal components to very tight tolerances. This is done using state-of-the-art CNC machines or screw machines that can easily handle the tight tolerances required for high-precision components. High precision machining is the preferred method, if not required method, for manufacturing certain parts in many industries, including automotive, aerospace, electronics, and medical.

This article will explore the benefits of using high precision machining and some of the different types of high precision machining services offered.


High precision machining refers to machining processes that produce highly accurate and consistent parts to exact specifications.  However, there aren’t any defined tolerance ranges that qualify a product as a high-precision workpiece. In general, part sizes and order volumes determine the difficulty of a particular tolerance.

High precision machining is a subtractive process, meaning that material is removed from a workpiece by the cutting tool. This contrasts with additive processes such as welding or casting. With those processes, material can be added during production for similar size/shape but different density.


High precision machining is used for manufacturing parts that require tight tolerances and high accuracy.

Industries that often use high precision machining include automotive, aerospace, and medical industries. In such sectors, flaws in a machined part can have catastrophic consequences. You certainly don’t want an aerospace part to fail while in midflight or a medical device to suddenly stop working. That is why so many quality-dependent parts rely on the consistent, high-precision of computer-controlled machines.

More Benefits of High Precision Machining

There are many benefits of high precision machining. Of course, the most obvious are the two we’ve mentioned already: tight tolerances and high accuracy. However, there are two more significant benefits to consider.

Can Be Adjusted More Closely & Easily

In industries like automotive or medical, where quality matters are critical, machining can be adjusted for more precise dimensions than what casting offers. Plus, instead of recasting, the parameters can simply be tweaked as needed.

Nice Finish

Furthermore, precision machining provides a nice surface finish while maintaining the quality and accuracy of the component. This makes it suitable for quality-sensitive applications such as electronics and aerospace manufacturing, where the need to maintain a good surface finish is critical.
