At this glorious moment, we jointly celebrate the 75th anniversary of the founding of the People’s Republic of China. 

The systematic error of a coordinate measuring machine (CMM) refers to the systematic deviation caused by factors such as the design, manufacturing, installation and use of the equipment itself during the measurement process. These errors are generally predictable and consistent when measurements are repeated under the same conditions. 

The dimensional deviation is the algebraic difference of the dimensions minus their nominal dimensions, which can be divided into actual deviation and limit deviation.

The industry has made great progress since the 1960s. With the rise of industrial production machinery, automobiles, aerospace and electronics industries, the development and production of various complex objects require advanced detection technology and instruments, which are reflected in the three coordinate measuring machine and three-dimensional measurement technology came into being, and have been rapidly developed and improved.

The scanning measurement is different from the trigger measurement, the measuring machine will bear the inertial load during the whole process, and the dynamic performance is more important than the static performance. Inertial load causes deformation of measuring machine structure, which is difficult to predict.

The CMM measuring range is the main factor in choosing a CMM. When we plan to buy a coordinate measuring machine (CMM), we should first know the surrounding size of the product, and then choose the CMM size. For example, when choosing a bridge coordinate measuring machine, the equipment price is proportional to the beam span, so we only need to meet the measurement range, do not pursue an unnecessary large range.

First of all, determine the power of the equipment, generally speaking, the power of the ordinary PC or industry is about 200w, the MAC is 300w, the server is between 300w and 600w, and the power value of other equipment can refer to the instruction manual of the equipment.

The daily maintenance of vision measuring machine is very important. Here are some common faults and some basic maintenance methods. Hope to be helpful to instrument users.

In order to make the CMM measure accurate results, the ambient temperature should be strictly controlled within the range of the CMM specification.

Coordinate measuring machine (CMM) is an integrated product that integrates mechanical, electrical and software, so its possible faults will involve all aspects and fields. We offer solutions according to the main reasons why CMM stops working as follows.

With the development of coordinate measuring machine (CMM) technology, CMM has been used more and more widely. Because the structure and material of CMM have great influence on the measurement accuracy, the precision of CMM is more and more demanding. Here are some common structural materials.
