MIC-JD2A length measuring machine—horizontal projection optimeter
The length measuring machine is a kind of instruments used for measuring the distance between two end faces of a measured piece: its end faces include plane or curved ones and exterior or internal ones. The length measuring machine are divided into optical ones, linear measuring instruments and linear measuring machines
The length measuring machine is widely used in the measuring rooms of the enterprises in the engineering industry, tooling, measuring implement manufacturing industry and instrument and metering industry, etc. And also used in the professional measurement and appraisal department at various levels.
Typical measured targets are:
External dimensions
- The measurement of the parallel plan for the measured piece, such as measuring blocks
- The measurement of the spherical dome for the measured piece, such as length baras, stell balls.
- The measurement of the cylin droid for the measured piece, such as axles, 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 the diameter of the threads
Characteristics:
- Reading from the projection reading screen
- Adopt new wax screen technology and reading magnifier, it has a symmetry view field’s illumination and clear image
- It has a high accuracy and reliable data
- The optimeter tube on the apparatus can be installed on the machine tool alone. It uses the measuring block to control the precision process.
