  • Tolerance classes
  • Checking and continually monitoring production processes yields a stable process quality throughout manufacturing. The focus of our quality management thus lies on the constant development of processes that are as error-free as possible, in addition to our unconditional dedication to the customer.
  • Constantly increasing quality requirements for cutting edges and tolerances of the slitting dimensions necessitate the smallest possible production tolerances for the tools used in the cutting process. Yafei addressed this problem very early on.
    Fully automatic production steps as well as complete machining processes ensure ultimate precision and short delivery times for our tools. The finish machining and final inspection are carried out at a temperature of 20°C, under standardized conditions.
  • With state-of-the-art production for cutting tools worldwide, we achieve process-ensured and guaranteed thickness tolerances of ± 0.002 mm and a drilling accuracy up to H3.
    To minimize sum errors in shaft design, we divide the thickness tolerance into three areas (-, 0, +) upon request, and we label each tool accordingly.
  • Depending on the requirements, Yafei offers tool surfaces that are ground to the level of mirror polishing. By means of proven measurement technology from the automotive industry, we verify the mean roughness values (Ra) ≤ 0.03 μm and gloss levels > 1000 GU (20º) of tool surfaces.
  • The division of tools according to tolerance classes offers you a high degree of flexibility. In line with the particular cutting task, we can offer the most economical tool solution in four tolerance classes for operating cutting systems.


Due to the wide range of applications of mechanical blades and a wide variety of applications. Before selling, we need to communicate with our customers
to understand the characteristics of blade use, materials, etc. to ensure the accuracy of our products. 
After the sale, we also carry out a return visit, timely understanding of the blade in the use of the problem and advantages, in order to facilitate
our next production in accordance with customer requirements, to further provide product quality.
Your knives from yafei blades are produced precisely according to your requirements. We are flexible and adapt our knives to suit your needs exactly.
