What types of CMM contact probes are there? Published: 2019-10-29 Source: http://www.microaccuracy.com/ As the sensor of a three-coordinate measuring machine, the probe is a very important component that affects the measurement accuracy, and different probes have their characteristics and applicable scenarios There are differences, so what types of CMM contact probes are there? The three coordinate measuring machine mainly adopts the contact measurement method, and the contact probe is divided into two types: mechanical contact probe and electrical contact probe. The following Miaoji Technology will introduce the difference between these two probes. : Mechanical contact probe: The mechanical contact probe is also called 'rigid probe' or 'hard probe'. It is generally used for 'static' measurement and is mostly used as a contact element. This kind of probe has no sensor system, no measuring range, no signal, but a purely mechanical contact head. The mechanical contact probe is mainly used for manual measurement. Due to the direct manual operation, the measuring force of the probe is not easy to control and is only suitable for general precision measurement. Due to its obvious shortcomings, the current three coordinate measuring machine has rarely used this kind of probe. Electrical contact probe: electrical contact probe, also known as 'soft probeWhen the sensor part of the probe always has a process of 'contact-deflection-transmit-responseThis kind of probe can be used not only for aiming, but also for micrometering, so it can also be subdivided into on-off probes for aiming and three-way probes with micrometering function. It is currently the most commonly used measuring probe for CMMs. head. In the structure of the three-coordinate measuring machine, the probe plays a very important role in measuring and sensing left and right. Therefore, choosing a suitable and high-quality probe can improve the detection accuracy of the overall equipment. As a domestic professional measuring equipment manufacturer, MiaoJi can currently provide a variety of high-precision coordinate measuring machines and one-button measuring equipment!
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.
