Precision Machining

A complicated and sometimes misunderstood process, precision machining is an important part of the manufacturing industry. Vital for creating many key parts in many industries, this method shapes larger pieces into smaller, more precise parts to meet the required specifications for the product, regardless of size.

What is Precision Machining?

This manufacturing process uses Computer Numerical Control (CNC) software to create 2D and 3D models to exact specifications through cutting, milling, and turning. Using precision machining services allows companies to have a more accurate product at a faster pace.


There are several CNC tools that professionals in the industry can use daily.


  • CNC Machining: Using Computer-Aided Design (CAD) software, professional designers can create digital design files that provide instructions to the equipment about which processes and tools to use.
  • Multi-Axis CNC Machining: Machine tools used during high-precision CNC machining have multi-axis capabilities. This machining lets different processes be performed simultaneously while reducing the time it takes to set up.
  • Swiss Machining: This type of CNC machining brings the stock to the tool rather than the other way around, allowing for precision tolerances within ±0.0001 inches.

What are the steps for precision machining?

The precision machining process has several key steps that allow it to be a precise, efficient, and effective way to create high-quality machine parts.


  1. Inspection of Materials: The raw materials needed for the creation of the product are inspected to ensure quality.
  2. Machining: CNC machinery processes the raw materials to meet the necessary specifications
  3. Heat Treatment or Surface Treatment: Depending on the circumstance, the parts can undergo a series of heating and cooling processes to meet hardness, metallographic, and mechanical specifications.
  4. Secondary Machining: After one or both treatments, the CNC machining process raw materials to meet product specifications.
  5. Inspection: The product is inspected for quality and to ensure it meets all the necessary specifications.
  6. Cleaning and Packaging: The product is cleaned and packaged for delivery.
