Oxford Dial Indicating Bore Gauges 59mm (2 3/16") Dial Diameter

Suitable for rapid, accurate measurement of size, concentricity, wear, taper, etc., in a wide range of bores. For workshop and inspection use. All models have one fixed and one moving anvil and a self-adjusting centre shoe. A "Datum Point" can be set by using a setting ring of a known diameter or a micrometer. "Zero" the gauge to this datum point by rotating the bezel to align "zero"with the indicator. To check a bore is within tolerance, the limit hands can be fixed as required. All anvils are spring loaded to expand into the bore. For accurate reading ensure the stem of the gauge is parallel to the axis of the bore. This can be checked by "rocking" the gauge back and forth until the smallest diameter is found. All models have inter-changeable anvils to cover a range of bore sizes.Type Metric.

牛津拨号指示仪表五九毫米孔（2 3 / 16“）表盘直径
适用于快速，准确测量尺寸，同心度，耐磨，锥度，钻孔等在一个范围广泛。车间和检验使用。所有型号都有一个固定的，一个个动人的铁砧和自我调节的中心鞋。一个“基准点”可以通过使用一个已知的直径或千分尺设置环。“零”的旋转表圈，使之与指标“零”规范这一基准点。要检查孔是在容许范围内，限制手可根据需要确定。所有砧装有弹簧进军孔。为了地读确保计干平行于孔的轴线。这可以通过检查“摇摆”的规来回，直到小的直径被发现。所有型号都有跨多变砧，涵盖了孔sizes.Type度量范围。
