ISO 286 is the international system of limits and fits for holes and shafts. Use the tables below to pick a fit such as H7/g6 or H7/p6, read the limit deviations for your size, and check the resulting clearance or interference. The values apply to parts made by CNC machining, rapid prototyping and low-volume manufacturing.
CNC Machining Design Guidelines 11 Practical Rules to Cut Cost and Lead Time A part can look perfect in CAD and still be slow, expensive or risky to machine. These are the design rules our engineers recommend most often, and each one is cheap to apply before production starts. CNC machines remove material with rotating

CNC (Computer Numerical Control) machining continues to be one of the most accurate and reliable manufacturing methods across industries. Its ability to produce complex, high-precision parts makes it a top choice for prototyping and low-to-mid volume production. However, the price is anything but fixed. Whether you’re paying $12 per hour for 3-axis milling at a
304 stainless steel and 316 stainless steel are materials we often use in rapid prototyping, sheet metal fabrication and CNC machining. Choosing between 304 and 316 stainless steel can be overwhelming. They are all durable and corrosion-resistant. But their chemical composition, cost, and performance in different environments is different. We will compare the key differences,

China has emerged as a global leader in CNC machining, offering high-quality, cost-effective solutions across industries. Here’s a breakdown of why partnering with a CNC machining company in
In CNC machining, accuracy isn’t just a goal—it’s a necessity. Achieving precision requires robust quality control processes and consistent inspection methods. By adhering to proven techniques, CNC manufacturers can ensure that each part meets specific tolerances, functions as expected, and has a smooth finish. This guide explores the methods, tools, and stages involved in CNC
What is CNC Milling? CNC (Computer Numerical Control) milling is a subtractive manufacturing process that uses rotary cutting tools to remove material from a workpiece, creating precise shapes and intricate designs. Unlike other CNC processes like turning—which spins the material itself—CNC milling rotates the cutting tool along multiple axes. This enables detailed cuts and complex
Precision and complexity are crucial in modern product development, especially when prototyping intricate designs. Complex geometries often pose significant challenges, including maintaining tight tolerances and ensuring structural integrity. Traditional methods struggle to meet these demands, leading to costly delays and design compromises. CNC rapid prototyping offers the perfect solution. With its high precision and versatility,
