It is mainly used in metal-processing industry, especially those measuring rooms or inspection stations of machinery industry and others industrial fields, such as tool-measure and instruments manufacturing.Features:1. High quality cast-iron base support, it has a good stability after long-term natural seasoning.2. Optimization design, make sure the structure with high performance and precision.3. Various kinds of accessories are provided, so it has good universal performance.4. It is equipped with optical grating measuring system, the measuring result is displayed in number visually.5. The illumination system of optical grating adopts infrared illuminator which is low voltage and current, small volume and long life.6. It uses Abbe's principle and high precision measuring system, so it has a high measuring precision.SPECIFICATIonMain Measure Work-pieces Include:1. Smooth columniform worpieces (Axis, hole, plug gauge and ring gauge etc )2. The MID-diameter of internal thread, external thread, thread plug gauge and thread ring gauge3. Workpieces with parallel plane (calipers, length bar and low-grade measuring block)Technical Parameter:Measuring range (mm):External size:Absolute measurement: 1-100Comparative measurement: 0-670Internal size:When using small measuring hook(maximum insert depth 12, maximum wall thickness 50): 10-400When using large measuring hook(maximum insert depth 50, maximum wall thickness 85): 30-370When using electronic measuring hook: 1-60mmWhen using universal measuring hook: 14-112mmMeasurement of internal thread MID-diameter:When using small measuring hook (thread small diameter 13-30mm)When using large measuring hook [thread small diameter 31 ~ (70 -wall thickness) X 2 ]Thread distance: 0.5~6 mmMeasurement of external thread MID-diameter: Maximum 200mm, thread distance 1~6 mmMeasuring force (N): 0, 1.5, 2.5Digital resolution: 0.1umAccuracy repeatability of the instrument:. External-size measurement 0.3μ M. Internal - size measurement 0.5μ MAccuracy of instrument:While direct measurement of external size, accuracy of instrument is superior to(0.5 + L/200) um for JD25-D and 0.5 um for JD25-CWhile measurement of internal size, accuracy of instrument is superior (1 +L/100) um JD25-D and 1 um for JD25-CUniversal worktable:1.
