The image measuring machine briefly introduces the three coordinate measuring machine
A brief introduction to the three coordinate measuring machine. A three-coordinate measuring machine refers to an instrument that can express geometric shapes, length, and circumference index within the space of a hexahedron, and is also called a coordinate measuring machine or a coordinate measuring machine. Mainly used in product design, mold equipment, gear measurement, blade measurement machinery manufacturing, fixtures, auto parts, electronic appliances, which is an important means of modern manufacturing, especially the design, development, processing and quality assurance of the mold industry. The following small series will explain two important functions of coordinate measuring machines in the mold industry: 1. Coordinate measuring machines have strong reverse engineering capabilities and are ideal digital tools. Through the combination of CMM probes and CMMs of different structures, 3D data and geometric characteristics of the workpiece surface can be quickly and accurately obtained, which is particularly useful for mold design, sample replication and damage repair. In addition, the contact scanning probe of the coordinate measuring machine can use the powerful scanning function provided by the measurement software to complete the replication of the CAD model of the complex workpiece with free-form surface shape characteristics. It can be directly identified and programmed through various CAD software without any conversion, which greatly improves the efficiency of mold design. 2. CMM can provide quality assurance for the mold industry, and it is a better choice for mold manufacturing companies to measure and test. The flexibility of the coordinate measuring machine in handling different tasks and its own high precision make it an arbiter. When CMM provides dimensional data for process control, it can provide additional performance, such as incoming product inspection, customer quality inspection, gauge inspection and mold workpiece inspection. The highly flexible coordinate measuring machine can be placed in the workshop environment and directly participate in all stages of mold processing, assembly, testing and maintenance, providing necessary test feedback, reducing the number of rework and shortening the mold development cycle, thereby ultimately reducing mold manufacturing The cost and amount of control. When the coordinate measuring machine is used to complete the design and test tasks of the mold manufacturing enterprise, it is necessary to pay close attention to the selection of measurement reference, the calibration and selection of the probe, the planning of the number of measurement points and measurement positions, the establishment of the coordinate system, and the impact of the environment. factor. Each of these factors is sufficient to affect the accuracy and efficiency of the measurement results. With high precision, high flexibility, excellent digital functions, high efficiency and high cost performance, the image measuring instrument coordinate measuring machine has become an important measurement tool in the mold industry.
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.
