In CNC machining parts (including CNC milling parts and CNC turning parts), injection molds and sheet metal parts. We often use: "International Tolerance Comparison Table".
In the complex world of precision manufacturing, precisely controlling tolerances is the core factor determining product performance and market competitiveness. As a professional cnc machining parts factory, Vanmodel deeply understands the strict requirements for precision in various industries. We are proud to announce that the carefully compiled International Tolerance Chart has now been made available on our website. It aims to help engineers and manufacturers quickly match processing techniques with tolerance grades, and at the same time, comprehensively showcase Vanmodel's outstanding precision manufacturing capabilities.
I. International Tolerance Chart: The "Golden Compass" of Precision Manufacturing
The International Tolerance Chart (ISO 286 standard) standardizes the tolerance range through IT grades (International Tolerance Grade), ranging from IT1 (extremely high precision) to IT18 (low precision), covering a total of 18 grades, comprehensively covering mainstream process requirements in the field of cnc turned parts, such as stainless steel turned parts and turning of aluminum parts. For example:
IT5 - IT8: Widely used in the processing of surgical instruments and implants in medical cnc machining, it can achieve a strict tolerance control of ±0.01mm, fully meeting the high requirements for biocompatibility and aseptic environment of medical products.
IT9 - IT12: Commonly used in the production of automotive structural parts or semiconductor equipment brackets, it performs well in balancing cost and performance, strongly supporting the large - scale production of oem parts machining.
With this chart, you can quickly query the tolerance ranges of different materials, such as stainless steel and aluminium, under specific IT grades, effectively avoiding a sharp increase in costs due to excessive pursuit of precision or assembly failures caused by overly loose tolerance settings. Vanmodel also provides professional tolerance analysis reports, combined with the GD&T (Geometric Dimensioning and Tolerancing) system, to help customers optimize their designs and reduce subsequent risks.
II. Vanmodel: A Professional cnc machining parts factory and a Leader in Precision Manufacturing
As an enterprise with more than a decade of experience in the field of cnc turned parts, Vanmodel provides one - stop high - quality services to global customers with its leading technical strength and rich industry experience:
Advanced Equipment and Exquisite Technology
Equipped with high - precision CNC lathes and milling equipment, it can achieve an ultra - high machining accuracy of ±0.005mm, fully meeting the nanometer - level accuracy requirements of Component test fixtures for semiconductor industry.
For turning of aluminum parts, PCD tools and efficient cooling technologies are adopted to effectively control thermal deformation and ensure that the surface roughness Ra ≤ 0.8μm.
Extensive Industry Coverage
Medical Field: Produces medical cnc machining parts that meet the ISO 13485 standard, such as joint implants and dental implants, and strictly implements biocompatibility tests to ensure the safety and reliability of medical products.
Semiconductor Equipment: Supplies high - quality parts of semiconductor equipment and test fixtures, fully supporting the ultra - precision requirements of wafer processing, packaging and other links.
Automotive Industry: Can deliver cnc auto parts in batches, such as engine blocks and transmission gears, perfectly adapting to OEM customized production requirements.
Strict Quality Assurance
Advanced coordinate measuring machines (CMM) are introduced for full inspection to ensure the consistency and high quality of each batch of parts.
Detailed tolerance analysis reports are provided to assist customers in optimizing their designs and significantly reducing later assembly risks.
III. High - Precision Challenges in medical cnc machining and Semiconductor Equipment Manufacturing
In the medical and semiconductor industries, the importance of tolerance control is particularly prominent:
medical injection molding and medical plastic parts must meet FDA certification, and the tolerance range usually needs to be strictly controlled within ±0.01mm to ensure the sealing and safety of medical devices.
The dimensional deviation of semiconductor test fixtures is required to be less than ±0.002mm. Otherwise, it is very likely to lead to misjudgment in chip testing, seriously affecting product yield.
Vanmodel's medical cnc machining team and semiconductor equipment manufacturing experts can provide customized tolerance solutions according to the specific needs of customers. For example:
For the turning of stainless steel 304, carbide - coated tools and water - soluble cutting fluids are used, and the cutting parameters (such as feed rate of 0.08mm/r and cutting depth of 0.5mm) are optimized to successfully solve the problems of work - hardening and heat dissipation.
For turning of aluminum parts, PCD tools and on - line laser diameter - measuring technology are used to achieve a super - mirror surface effect with a surface roughness Ra ≤ 0.01μm, meeting the strict requirements of electro - vacuum devices.
