A selection of CNC machined materials including aluminum, steel, stainless steel, engineering plastics, and composite materials, showing the wide range of materials that can be processed by CNC machines.
CNC machining materials include a wide range of metals, plastics, composites, and specialty materials, each offering different properties, machining characteristics, and application benefits. This guide covers the main types of CNC materials, their key properties, common applications, material grades and standards, and their suitability for different machining processes. It also explains how factors such as strength, weight, corrosion resistance, temperature resistance, machinability, surface finish, and cost affect material selection, helping you choose the right material for custom CNC machined components.
This guide covers essential CNC machining design principles, including tool accessibility, wall thickness, hole and thread design, internal corner radii, CNC machining tolerances, technical drawings, and Design for Manufacturing (DFM) practices. By optimizing part design before production, engineers can improve manufacturability, reduce machining costs, shorten lead times, and create reliable, production-ready CNC assemblies.
CNC rotary engraving is a precision machining process that creates permanent markings, text, logos, and identification features by removing material with a rotating cutting tool. This article explains how rotary engraving works, suitable materials, engraving tools, benefits, design considerations, industrial applications, and the differences between rotary engraving and laser engraving to help you choose the right marking solution for your parts.
Accurate thread measurement is essential for identifying the correct thread specification and ensuring proper component compatibility. This guide explains how to measure thread size by checking key dimensions such as thread diameter, pitch, threads per inch (TPI), and thread angle. It covers common measurement methods using thread pitch gauges, calipers, rulers, and thread comparison techniques, along with the differences between metric, UNC, UNF, and pipe thread standards. By understanding proper thread measurement methods and inspection practices, manufacturers and engineers can avoid thread mismatches and ensure reliable assembly performance for mechanical components and CNC machined parts.
CNC Machining Processes and Comparison CNC machining has become one of the most widely used manufacturing methods for producing precision
