18 Years Factory Vertical Linear Stages – Precision Motorized Z-Positioners - Precision ceramic square ruler – ZHONGHUI

●  To obtain the assembly accuracy of machine tools.

●  To measure the motion accuracy (straightness, squareness) of 3D measuring machines, etc.

●  To measure the straightness and squareness of high-precision components.

●  Best suited for high-precision measurement

High precision measurement of squareness and straightness to within 2 μm or less per up to 1000 mm achieved.

●  Lightweight and easy to measure and carry around

As compared to the 4-plane finished square masters made of Metal and Granite, a ceramic master is lightweight and is easy to measure and carry around.

●  Small deflection and superb abrasion resistance

Because of its light weight and high rigidity, the master provides small deflection under its own weight and outstanding abrasion resistance. (Young’s modulus: 380 GPa)

●  Little change over time

The ceramic 4-plane finished square master provides high hardness and outstanding abrasion resistance. Furthermore, it has a small coefficient of thermal expansion, which results in small deformation caused by temperature changes and makes it less susceptible to environmental influences during measurement.

We use various techniques during this process:

●  Optical measurements with autocollimators

●  Laser interferometers and laser trackers

●  Electronic inclination levels (precision spirit levels)
