How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

Hall Sensor

The Hall effect is the working principle of the Hall sensor. It is a kind of electromagnetic effect, in which an orthogonal current and magnetic field are applied to the Semiconductor. The carriers in the Semiconductor are subjected to the Lorentz force and deflected. In different directions Gathering, thereby generating an electric field. There is a built-in voltage, this voltage is the Hall voltage, the greater the magnetic field strength, the greater the Hall voltage.

Hall Sensor
Hall sensor

The working principle of the linear Hall sensor, the output of the linear Hall sensor is an electrical signal proportional to the measured magnetic field strength. For example, the linear Hall sensor 3503 has three pins which are positive VS, V out and GND. Among them The positive VS is connected to a power supply of 4.5 to 6V. Power is supplied to the 3503, and the GND is grounded. The shell of the 3503 can induce the magnetic field, and implements the magnetic field strength in the form of voltage output at the pin of V out. The next output diagram shows that the 3503 is good When the magnetic field strength is 0 Gauss, V out is equal to 2.5V. When the magnetic field strength changes by 1 Gauss, the output changes about 1.3 millivolts.
When the 3503 sensor measures the magnetic field, it needs to pass the magnetic field lines through its effective sensing element to be detected. The magnetic field lines pass through the Hall sensor. The stronger the magnetic field, the more magnetic field lines pass through the Hall sensor, and the weaker the magnetic field passes through. The fewer lines of magnetic force, the Hall sensor outputs a corresponding signal to indicate the strength of the magnetic field according to the number of magnetic lines that pass through.
