1.PCB Diamond V Cut Blade Overview<\/h2>\n
PCB Diamond V Cut Blade<\/strong> (also known as a V-knife or V-groove cutting blade) is a core processing tool in PCB manufacturing. Designed specifically for V-groove cutting\u2014critical for cutting PCB boards into individual units without damaging components\u2014it utilizes a diamond-coated blade edge for exceptional hardness and wear resistance. Compatible with both manual V-cut machines (for low-volume production) and automatic CNC V-cut machines (for high-volume production lines), it is suitable for a wide range of PCB types: single-sided, double-sided, multi-layer, halogen-free, FR-4, high-TG, aluminum, and copper. As part of our comprehensive PCB production solution, it works seamlessly with a Nylon brush for blade cleaning, an anti-static PP sheet for storing finished PCBs, and a PVA Sponge Roller for wiping the PCB surface after cutting, providing end-to-end support for PCB factories.<\/div>\n

Core Material and Hardness<\/h3>\n

Unlike standard Tungsten Carbide Blade<\/b> or HSS blades, this product uses a dual-material approach:<\/p>\n

    \n
  • \n

    Base Material:<\/b> High-Speed Steel (HSS) base with a hardness of HRC 62\u201365, providing the necessary structural integrity for high-speed rotation.<\/p>\n<\/li>\n

  • \n

    Cutting Edge:<\/b> A Diamond Coated Blade surface with a minimum hardness of HV 8000. This Diamond Coating drastically enhances Wear Resistance, extending the Tool Life up to 3 times longer than traditional blades.<\/p>\n<\/li>\n<\/ul>\n

    \u00a0Geometry and Precision<\/h3>\n

    The blade is a Rotary Blade<\/b> available in a customizable V-Cut Angle<\/b> range (30\u00b0\u201390\u00b0, typically 45\u00b0 for standard separation). Precision is maintained through strict tolerances (\u00a00.5\u00b0<\/span>\u00a0for the V-angle), ensuring a clean, burr-free V-Grooving process.<\/p>\n
