It is more abrasion resistant than a hardened steel ball and, as its surface is smoother than that of a carbide tip, the workpiece is less liable to be marked.Comparison of abrasion resistanceInspection method• Load a 0.5 N weight on the anvil, and slide for 1,000 m on abrasive paper of 9 μm (#2000) particle size.Comparison of marks on the workpieceInspection method• Load a 4 N weight on the anvil, and slide on the aluminum plate back and forth for 20 times.Abrasion depth: 0.1 mm750 HV or moreHardened steel ball (conventional model)Carbide tip(conventional model)Abrasion depth: 0.001 mm1350 HV or moreCarbide ball(current model)Carbide ball(current model)形状測定結果縦倍率 2,000 横倍率 200深さ:10µm形状測定結果縦倍率 2,000 横倍率 200深さ:1µm以下Ra0.4ø6SR3Ra0.06ø6SR2.5Result of contour measurementResult of contour measurementVertical magnication: 2,000Horizontal magnication: 200Depth: 10 µmVertical magnication: 2,000Horizontal magnication: 200Depth: 1 µm or lessRa0.4ø6SR3Ra0.06ø6SR2.5SR0.75 Carbide ballAnvilContact pointInch: ø9.53Inch: 2311.96.4100123Metric: 32Metric: ø8ø9Approx. 804.3ø12.718 - 35 mm/0.7 - 1.4 in
