Cutting Die Buttons ISO 8977

Precision stamping and blanking operations demand components that offer unwavering consistency, durability, and exacting dimensional accuracy. This is precisely where high-performance die buttons become critical. For applications requiring robust support and precise alignment within a die set, Shoulder Type Die Buttons provide an excellent solution, featuring an integral shoulder that ensures positive location and enhances stability during high-impact press work. When your specifications call for components adhering to stringent international standards, our range of Headed Die Buttons ISO 8977 Type B is engineered to meet the exact dimensions and tolerances outlined in the ISO 8977 standard, guaranteeing global interchangeability and reliable performance in the most demanding production environments. Both types are manufactured from premium tool steels and undergo rigorous heat treatment processes to achieve optimal hardness and wear resistance, directly contributing to extended tool life and reduced downtime.


The Cutting Die Buttons ISO 8977 series represents the pinnacle of standardized tooling component manufacturing. Designed for universal compatibility and peak performance, these buttons are essential for maintaining precision in progressive dies, compound dies, and other precision stamping setups. Their manufacturing adheres to the strict geometric and material guidelines set forth by the International Organization for Standardization, ensuring that every unit delivers predictable and repeatable results. Below are the detailed technical specifications and parameters for our standard Cutting Die Buttons ISO 8977 range.

  • What factors determine the precision of CNC machining?

    When measuring the linear movement of CNC machining, linear detection elements are generally used, known as direct measurement. The position closed-loop control formed by this is called full closed-loop control, and its measurement accuracy mainly depends on the accuracy of the measuring elements, which is not affected by the transmission accuracy of the machine tool. Due to the precise proportional relationship between the linear displacement of the machine tool worktable and the rotation angle of the driving motor, the method of indirectly measuring the worktable's movement distance by driving the detection motor or screw rotation angle can be used. This method is called indirect measurement, and the position closed-loop control formed by it is called semi closed loop control.
