How to choose a suitable two-dimensional measuring instrument according to measurement needs? Post time: 2019-11-29 Source: https://www.microaccuracy.com/ In the field of industrial production, the two-dimensional measuring instrument can play an important quality control role. It can achieve accurate measurement of the two-dimensional plane of the workpiece, but the market There are many types of two-dimensional measuring instruments. How should companies choose the right two-dimensional measuring instruments according to their measurement needs? Due to differences in products and quality, different companies have different requirements for the measurement of the second dimension. Therefore, companies should make appropriate choices according to their own product measurement requirements: according to the batch size of the workpiece: the small batch size selects the second dimension measuring instrument for ordinary measurement. Large batches of gauges and inspection fixtures are used to improve measurement efficiency. According to the structure and weight of the workpiece: light, small and simple workpieces can be measured on a two-dimensional measuring instrument, and large and complex workpieces should be measured with an upper-mounted measuring instrument, that is, the measuring instrument is taken to the workpiece for measurement. According to the size and requirements of the workpiece size: Determine the specifications of the two-dimensional measuring instrument according to the size of the workpiece, so that the measuring range of the measuring instrument can accommodate the workpiece, and the measuring head can extend into the measured part. Choose according to the required error of the workpiece: Generally, the maximum allowable error of the two-dimensional measuring instrument is 1/3 to 1/10 of the tolerance of the workpiece. If the measured workpiece is a measuring equipment, the tolerance must be 1/10; if the measured workpiece is a general product, the tolerance should be 1/3~1/5; if the measuring instrument conditions do not allow it, it can also be the tolerance 1/2, but at this time the confidence level of the measurement results has dropped accordingly. Sensitivity selection: In addition to the measurement requirements, you must also pay attention to the sensitivity of the equipment when choosing a two-dimensional measuring instrument. If the sensitivity is too low, it will affect the accuracy of the measurement. If it is too high, it will be difficult to achieve a balanced state in time. If an enterprise wants to buy the right two-dimensional measuring instrument equipment, it must first understand its own needs, and then choose equipment with appropriate functional parameters according to the needs. As a professional measuring equipment manufacturer in China, Miaoji Technology can currently provide a variety of specifications and types of high-quality two-dimensional measuring instruments.

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.
