How to achieve precision machining requirements for precision mechanical parts


All the personnel engaged in precision machining know that in order to process a reasonable precision hardware, in addition to the need to purchase sophisticated processing equipment, sophisticated testing equipment is also essential, including three yuan, altimeter, hardness tester, micrometer and so on.

Three-dimensional measuring instrument: An instrument that mainly measures precision mechanical parts by taking three-dimensional points. The three-dimensional element is also commonly called the three-coordinate. The reason is that the workpiece is placed in the three-dimensional measurement space, and the coordinate position of each measuring point on the measured object can be obtained. The measuring personnel can calculate the spatial coordinate value of the measured point. The geometry, shape and position of the object being measured.

The three-dimensional measurement principle is stated above, so which position can it be used for measurement? It can measure the shape of the ball, the shape of the cylinder, the shape of the cone, etc. It can also measure the curve. After the analysis of the software, the size is digitized, the number is displayed, and then the computer is used to process the geometric quantity, which can be better and better. Control the precision of precision mechanical parts processing.

Altimeter: An instrument used to measure the relative height of a space point. It can measure the height, depth, groove width, inner and outer diameter, hole center distance, axial distance, flatness and verticality of precision mechanical parts. When measuring, it is reasonable to match the height ruler and the lined claw so that the line drawn on the workpiece is parallel to the platform, and the height ruler should be matched with the lever dial gauge, which can reduce the measurement error.

Hardness tester: literally, a test instrument for measuring the hardness of a material, indicating the ability of the material to resist the pressing of a hard object into its surface. The hardness is high and the wear resistance is good.

Finally, precision machining manufacturer Shilihe Electromechanical Equipment Co., Ltd. reminds you: three yuan, height meter, these precision instruments, there are certain requirements for ambient temperature and humidity, the best working environment: temperature (20 ± 2) ° C, The humidity is 55%-65% in order to ensure the accuracy of the data.
