Principal benefit of Low Flow Micro Shot Peening Machine

By this technology, particulate flux and projection velocity can be controlled only by the gas pressure level of compressed air and consequently, extremely low particulate flux has become available which was not with conventional devices. It is confirmed that by such low level projection, microdimples are built on the surface of the target and additionally, it is possible to give different functionalities such as solid lubricity and oil repellency by affixing submicron particles around the surface of general-purpose steel beads. Microcrystalization of surface part by projection is also possible.

IKK is continuing further technical development in this area including new modification treatment methods to orbital plane of rolling bearing, blade edge of tools and more. Application for drilling to hard-to-work materials like CFRP, by narrowing projection area, will be investigated, too.

Applications of Low Flow Micro Shot Peening Machine

  • objects which require low friction and high wear resistance like sliding surfaces
    e.g. inner and outer rings of rolling bearings, shaft, working tools (drills, screw-taps, cutting tools, cutting tips
  • objects which require residual stress without lowering surface roughness
    e.g. small gears
  • objects which require improvement in oil repellency and elasticity by projection adhesion of fine powders only on surface
    e.g. crusher tips
  • hard-to-work objects
    e.g. CFRP
