POROUS SINTER PLATE, VACUUM SUCTION PAD USING THE SAME, AND PRODUCTION METHOD OF POROUS SINTER PLATE
PROBLEM TO BE SOLVED: To provide a porous sinter plate which can suck a workpiece in a uniform state as a suction plate of a vacuum suction pad, a vacuum suction pad using it, and a production method of the porous sinter plate.SOLUTION: The porous sinter plate has an integrated-plate shape sinter composition and has a suction action part and a non-suction action part formed of sinter composition areas having different gas permeability. For producing such a porous sinter plate, by radiating and scanning high energy beam, powder bodies are laminated and sintered in a plate thickness direction, and by changing a degree of sinter, the suction action part and the non-suction action part having different gas permeability are formed in a suction surface.
【課題】真空吸着パッドの吸着板として、ワークを均一に吸着可能な多孔質焼結板、これを用いた真空吸着パッド、及び多孔質焼結板の製造方法を提供する。【解決手段】一体板状の焼結組織を有する多孔質焼結板であって、吸着面内に、気体透過性の異なる焼結組織領域で形成される吸着作用部と非吸着作用部とを有する多孔質焼結板とする。かかる多孔質焼結板を製造するには、高エネルギービームの照射と走査により、粉体を板厚方向に積層焼結するとともに、焼結度合いを変化させて、吸着面内に、気体透過性の異なる吸着作用部と非吸着作用部とを形成する。【選択図】図１
