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

What is the principle of a power transmitter?

The power transmitter is a combination of multiple precision parts and requires careful use and maintenance. Before using a power transmitter, you need to know its principle.

What is the principle of a power transmitter? Introduction to the principle and characteristics of power transmitters

Principle of power transmitter

transmitter

The power transmitter is mainly composed of three-phase isolated sampling circuit, A/D converter, single chip microcomputer, DSP device, D/A converter, calibration amplifier and special thick film integrated V/I converter.

After the three-phase AC input signal passes through the three-phase isolation sampling circuit, the common ground tracking voltage signal of the three-phase current and the three-phase voltage signal is formed. Under the control of the single-chip microcomputer, the A/D converter performs multi-point synchronous sampling on it, and the sample is obtained The data is calculated by the DSP device according to the principle of electrical engineering to calculate the three-phase active power (digital quantity) of the measured signal, and then the digital signal representing the three-phase power is converted into an analog quantity by the D/A converter, which is amplified and calibrated by the calibration amplifier Then, a direct current voltage output VZ is formed; the VZ output is passed through a dedicated thick film integrated V/I converter to form a 0-20mA or 4-20mA direct current output IZ.

Performance characteristics of power transmitter

As a professional instrument salesperson, you must be familiar with the characteristics of power transmitters and be more professional when communicating with customers.

The three ports of analog output, input, output, and power supply are isolated from each other.

Good linearity and high precision.

Automatic zero calibration and excellent temperature characteristics ensure the long-term stability of the instrument and avoid the need for periodic calibration of the transmitter.

All parameters are digitally calibrated. The analog adjustment of the conventional potentiometer is abandoned, the hardware circuit is simplified, and the reliability and stability of the whole machine are improved.

Perfect electromagnetic compatibility design, with strong anti-electromagnetic interference ability.

Full use of SMT devices, so that the product has the advantages of small size, low power consumption, and light weight.

Digital output

The input is isolated from the power supply and the output. For power transmitters using optical fiber transmission, the optical fiber not only plays a transmission role, but also plays a role in isolation. It can completely avoid the loss and interference of the transmission link, and is suitable for high-precision measurement in various complex electromagnetic environments;

The digital output transmitter is convenient for networked and intelligent applications.

The digital output power transmitter can form a virtual instrument together with the transmission system and the host computer. The function and display mode of the virtual instrument are determined by the software, which can realize multi-parameter values, meters, real-time waveforms, trend curves, and bar graphs. , Pie chart, vector diagram and so on.
