The JD18 projecting universal length measuring machine is available from Exact Metrology.

Features:

  • The wax-screen technique is adopted for the projecting screen, clear in imaging and homogeneous in brightness of the field
  • High-quality cast iron through long-term aging treatment is adopted for the base frame, strong in rigidity and good in stability
  • The double- and single-wire reading system is adopted, precise in pointing and accurate in measurement
  • The worktable can move, rotate and out-beat in every direction, convenient for the detection of parts in different forms
  • This instrument equipped with multiple accessories of tailstock, measuring hooks and caps, etc., large range in measurement

Usages:

  • The projecting universal length measurer is a kind of linear measuring instrument integrated fine mechanics, optical system and electrical parts into an organic whole
  • This projecting universal length measurer is used for direct measurement and comparative measurement for dimensions of parts and components and makes special-purpose extra-equipment to the instrument carry out various special measurements

The scope of uses is as follows:

External dimensions:

  • The measurement of the parallel plane for the measured piece such as measuring blocks
  • The measurement of the spherical dome for the measured piece such as length bars, steel balls
  • The measurement of the cylindroid for the measured piece such as circular cylinders

Internal dimensions:

  • The measurement of the parallel plane for the measured piece such as snap-gauge
  • The measurement of the aperture such as ring-gauges

Screw thread:

  • The measurement of external and internal effective diameter of threads

Comparative measurement:

  • The horizontal projecting optical gauge line and large-or-small movable measuring hooks are used to conduct comparative measurements for internal and external dimensions
