Super-hard tooth formation on linear edge saw blades using Selective Laser Melting process - SmartTeeth

C4碳化物创新的锯片开发计划将使用选择性激光熔化(SLM)，这是一种金属添加剂制造(AM)技术，将超磨料粉末熔化成工具级硬质材料，形成净形状的‘锋利’切齿，消除后处理磨削的需要。这一概念的英国专利已经申请。与传统的碳化钨锯片(TCT)相比，AM工艺为客户定制的专业应用创造了高性能的切齿。数字化制造流程使C4能够满足具有挑战性的设计更改，并快速响应客户的要求。与传统的TCT叶片制造相比，SLM可以节省70%-80%的材料，节省50%以上的能源和生产。为了确保AM齿形创新的成功，四个关键因素是至关重要的：1.通过SLM识别和开发高性能超硬材料的使用。用于添加剂制造的新的优化齿形设计。在连续预制带材上对准和精确成形超硬牙齿方面的工艺创新。可提供一系列新的刀具几何形状，并可在同一天根据客户对新材料和新设计的具体要求进行生产。我们的目标是在这个项目成功完成后的5年内改造线性边缘市场。

"C4 Carbides innovative saw blade development program will use Selective Laser Melting (SLM), a metal Additive Manufacturing (AM) technology, to fuse super-abrasive powder to form tooling grade hard materials into net shape 'sharp' cutting teeth, eliminating the needs of post process grinding. UK patents for this concept have been filed.Compared to conventional tungsten carbide tipped (TCT) saw blades, the AM process create high performance cutting teeth for specialist applications tailored to customer specifications. The digital manufacturing process enable C4 meeting challenging design changes and fast respond to customer's requirements. SLM allows material saving of 70-80% and energy and production savings of over 50%, as compared to conventional TCT blade manufacturing.To ensure the success of the AM tooth formation innovation, four key elements are crucial:1. Identifying and developing the use of high performance super-hard materials by SLM.2. New optimised tooth designs for additive manufacturing.3. Process innovation in aligning and precisely forming super-hard teeth on continuous preformed strip.4. Technology scale up for serial production.A new range of cutting tool geometries can be offered, and specific customer requirements for new materials and designs can be made the same day. We aim to transform the linear edge market within 5 years of successful completion of this project."
