What is the cause of the noise of the image measuring instrument?
What caused the noise of the image measuring instrument? As a high-precision measuring instrument, the image measuring instrument will not have slight errors. During the measurement process, if there is a sound problem when the coordinate measuring machine is moving, the user needs to pay attention. If it is not handled properly, it will greatly affect the accuracy of the coordinates. In order for you to better understand and use CMM, let us analyze the reason why CMM makes a sound. 1. Pneumatic shock: There are many kinds of pneumatic shock. One is caused by the vibration of the motor of the coordinate measuring machine. If there is emergency pressure, there should be no sound. The other is because the gas of the floating block happens to resonate with the surroundings. When I press the emergency button, there is still a sound. Change the inlet pressure slightly, and change the frequency of gas vibration to eliminate the vibration of the CMM. 2. Mechanical part: The transmission device of the three-dimensional measuring machine or the air flotation block or the reading head has a sound during the movement. There may be obstacles to transmission. There may be friction between the air flotation block and the read head. These problems can be solved by supplying air to the machine. Push the axis of the three-dimensional sound to judge. If it is a mechanical problem, you can hear it at this time and find the place where the sound is made. 3. Electrical system: the three-coordinate motor is not suitable for this parameter. When the state of the machine changes, it may get an electric shock and make a lot of sounds. If you press the emergency button, the sound will disappear. When making a sound, you should feel it when you touch the motor. To a noticeable vibration. The operator's familiarity with the image measuring instrument determines the application of the coordinate system in the measurement. Only with a full understanding of the basic situation of the coordinate measuring instrument can the coordinate measuring instrument be better used to complete the measurement task.
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
