Lihe Precision invests heavily in R&D every year and is committed to the independent development and research of products. This has given Lihe Precision rich experience in the design, manufacturing and operation of coordinate measuring machines.

Based on this valuable experience, we have developed a strict testing procedure for the stability, repeatability accuracy and other performances of coordinate measuring machines. Let's take a look at the tests passed by Lihe Precision's classic moving-bridge coordinate measuring machine, which is the common choice of enterprises in mold, new energy vehicle, digital 3C and other fields.

Machine stability test

To ensure machine stability, we conduct thousands of hours of mechanical movement running-in cycle tests and verification after assembly. The ultra-high rigidity inert material—natural granite—ensures the stability of the whole machine, reduces deformation caused by force and temperature factors, and extends service life. Other components of the machine, such as air bearings, cylinders and grating rulers, also meet the standards of imported coordinate measuring machines.

Repeatability accuracy test

There are many factors affecting the repeatability accuracy of coordinate measuring machines. The components and three axes of Lihe Precision's classic moving-bridge coordinate measuring machine have passed repeatability tests and consistently maintain a measurement accuracy of 2μm. Therefore, the classic moving-bridge coordinate measuring machine is widely used in enterprises in mold, new energy vehicle, digital 3C and other fields. It can exert the machine's optimal dynamic performance during measurement and realize the measurement of various complex workpiece shapes such as curved surfaces and holes.

Travel test

When selecting a coordinate measuring machine, customers will consider the machine's travel, hoping to achieve all-directional measurement without dead angles. Lihe Precision verifies the effective travel of the three axes of the classic moving-bridge coordinate measuring machine to prove the accuracy of the travel.

Measurement speed and acceleration test

Tests show that the classic moving-bridge coordinate measuring machine can reach a maximum 3D running speed of 700mm/s and a maximum acceleration of 1000mm/s², and the machine can operate normally at this speed and acceleration.

Strict self-testing is not only a self-endorsement of Lihe Precision's products, but also ensures the quality of Lihe Precision's products.
