Cutting Edge of Fine Blanking Technology
SJ Technologies not only provides a full set of fine blanking production line equipment but also our technical team to provide comprehensive technical support and training services.
Fine blanking produces close tolerance parts from materials of higher thickness. Cut edge is 100% free of tear and in most cases parts are suitable for mechanical function without the need for subsequent machining. This technology enables productions of “Near net shape” and even ready to assemble sheet metal parts.
Working Principle of Fine Blanking
Compared to normal blanking, fine blanking operation is more precious, product high precision requirements, no collapse Angle, no burr, the full bright belt is the difficulty of stamping process, the use of ordinary blanking process cannot avoid burr, collapse angle.
Fine blanking technology is a special method to solve this kind of product.
Fine Blanking VS Stamping
Fine blanking originated from general stamping, but it is not simply an enhanced version of general stamping. The essential difference between the fine blanking process and the general blanking process is that the general blanking cannot effectively avoid the generation of tears in the section when punching, while the fine blanking tries to inhibit the occurrence of tears in the sheet material by all means when punching.
The following are the differences between fine blanking and general stamping.
Difference in requirements of materials to be processed
Ordinary stamping can process almost any material, as long as the die steel is strong enough and the press pressure is sufficient.
However, the materials used for fine blanking require good plasticity, low flexural strength ratio and high elongation of the material to be processed because of the need to effectively transfer compressive stress between material crystals to inhibit cracking.
Differences in processing capacity characteristics
General punching limit size
Stamping: Minimum hole diameter of 1.5 times the material thickness.
Fine blanking: minimum whole diameter up to 0.6 times the material thickness.

FAQ’s
What is fine blanking parts?
Fine blanking (also known as fine-edge blanking) is a special type of stamping process that produces parts of enhanced accuracy, flatness, and edge characteristics when compared with conventional stamping.
What is the fine blanking method?
Fine Blanking is a unique development in the metal forming industry that applies precision mass production techniques. Although innovated from traditional metal stamping, Fine Blanking employs a system of machine movement, tooling and plastic deformation of metal.
What are the components of a blanking tool?
Blanking tool consists of two main parts, a punch and a matrix. The matrix fulfill the bottom function of the hard knife and the punch fulfill the upper function of the knife, the cutting press tool. At the same time, there are guiding elements: guide plate, guide posts and column guide sleeves.
What is the difference between blanking and fine blanking?
Definition. Both blanking (stamping) and fineblanking are processes for producing sheet metal parts. Fineblanking is a highly sophisticated technology for the production of high-precision three-dimensional stamped parts.
Which press is used for fine blanking?
Hydraulic fineblanking presses are noted for extreme precision of the slide guiding over the entire length and width directly on the press uprights.
Why is blanking used?
Furthermore, because the primary metal stock can be reused, blanking can help manufacturing firms reduce their material waste. Due to these benefits, blanking is commonly used to mass produce components for industries such as aerospace and automobile manufacturing.
