Universal Length Measuring Machine

It features in high accuracy due to adopting Abbe comparative theory and a high precision measuring system. It is mainly used in measuring office of factories and various level measuring departments in metal machining industry, specially in machine manufacturing, bearing manufacturing, gauge manufacturing as well as precision tools manufacturing and instrument manufacturing industries.

Comprising with the traditional ones, the machine adopts raster digital display technology, and it is a high technical product integrating optical, mechanical and electric (computational algorithm), improving its accuracy and work efficiency greatly. It also adds several auxiliary accessories to improve its universal applications.

Applications:

1. Shaft, hole, plug gauge, ring gauge, clip gauge, length bar, cone, cylindrical workpiece, lower-grade block gauge, workpiece with parallel planes etc.

2. Pitch diameter of internal thread, thread, thread ring gauge, thread plug gauge.
