What are the classifications of the stylus of the three coordinate measuring machine? The measurement system of the coordinate measuring machine is composed of a calibration system and a probe system. They are the key components of the coordinate measuring machine and determine the accuracy of the CMM measurement. The three-coordinate stylus is an integral part of the probe system of the coordinate measuring machine. It is mainly used to contact the surface of the workpiece and move in the probe's mechanical device to generate signal triggers and collect measurement data. The most widely used styli on the market today is made of ruby. Three-coordinate stylus can be divided into the following categories: Ceramic hollow spherical stylus: very suitable for detecting deep, X and Y-direction features and holes, only one ball is needed to calibrate. Spherical styli: This is a simpler styli. Suitable for most test applications. The material mainly uses industrial ruby u200bu200bwith high hardness and strong wear resistance; it is a widely used stylus type; Cylindrical stylus: used to detect holes in plates and various threaded parts. Star stylus: It is installed on the stainless steel star pen holder through four or five ruby u200bu200bball measuring systems. These styli can be used to measure various body structures and multi-point detection for complex shapes and holes. Disc-shaped stylus: The disc-shaped stylus is cut off near the center of the ball; it is used to detect undercuts and grooves in holes that cannot be reached by the star-shaped stylus; Special stylus: For thread profile, thin section Materials, tool settings and other special measurement applications. Dedicated stylus: dedicated to detecting thread contours, specific points and score lines; one of the key factors in how to choose a suitable probe for an image measuring instrument In order to perform effective detection, a probe probe is selected. For users, whether they can perceive features and ensure accuracy during contact is the key, and it is necessary to understand the knowledge of stylus.
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.
