SLS和FDMS制造超薄金刚石锯片对比研究

Comparative study on ultra-thin diamond saw blades made by SLS and FDMS

提出了一种使用增材技术制造金刚石工具的新思路,即使用熔融沉积成型烧结(FDMS)工艺来制造超薄金刚石锯片。详细介绍了选择性激光烧结(SLS)工艺和FDMS工艺在超薄金刚石锯片制造中的应用,并从主要设备仪器、工艺原理、工艺步骤以及成型材料、成本与生产应用等角度,对2种工艺进行比对。研究发现:在选择合适材料的条件下,2种工艺均能够制造出精度极高、性能优良的金刚石超薄片。SLS工艺具有能耗较高、成本昂贵,工艺简洁、一次成品等特点,适合于超薄金刚石锯片的研发等用途;FDMS工艺环节较多,且每个环节需单独优化参数,工艺流程较烦琐,但其便于批量生产性能一致的产品。FDMS工艺所制试样能够具备与传统粉末热压烧结试样相近的物理力学性能,但仍有一定的优化空间。

Additive manufacturing for diamond tools is introduced into ultra-thin diamond saw blades,using the fused deposition molding sintering(FDMS).The application of selective laser sintering(SLS)and the FDMS in manufacturing ultra-thin diamond saw blades are introduced in detail.And they are compared from the perspectives of basic equipment,process principles and steps,materials,costs,and applications in production.The results show that both the processes possess the ability to manufacture diamond ultra-thin slices with strikingly high precision and excellent performance under the condition of selecting suitable materials.SLS is characterized by high energy consumption and cost,simple process and one-time finished manufacturing,suiting for the research and development of ultra-thin diamond saw blades.FDMS process has many complicated links,and each parameter of the link needs to be optimized separately.However,it is convenient for mass production of products with consistent performance.
