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 bett...

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th...

Introduction of KOVAR parts

KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR  machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stre...

What are the functions of GPS vehicle positioning system?

What are the functions of GPS vehicle positioning system? The GPS vehicle positioning system implements tracking of one or more designated vehicles. With the movement of the vehicle, the electronic map can be automatically zoomed, so that the target always falls in the window, and the vehicle is tracked according to the tracking priority at the set time interval. Intuitive movement trajectory.

At present, the GPS system has been connected to the whole country and connected with 110 of public security agencies in various places. Even if the vehicle leaves the jurisdiction, as long as it is within the network coverage, it can get timely service. You will receive an alarm at ** time. After receiving the alarm, the monitoring center informs the staff on duty through sound and light alarm, and moves the alarm vehicle to the center of the screen, and displays the coordinate location, attributes, pictures, isomorphism category, occurrence time, etc. of the alarm vehicle to help the police deal with it .

What are the functions of GPS vehicle positioning system?

(1) Query now

After the monitoring center issues an immediate command, the GPS terminal uploads the location information (including longitude, latitude, azimuth, speed, number of satellites, etc.) and status information of the vehicle, person or pet in time.

(2) Remote tracking

The monitoring center can set the GPS terminal on the monitoring software for timing tracking settings, and can set a fixed time to upload the location information and status information. Once the setting is successful, the GPS terminal will upload the requirements of the monitoring center in time according to the instructions issued by the monitoring center Information.

(3) Urgent help

When a driver or an individual wearing a GPS terminal encounters a special situation, he can ask the monitoring center for help through the emergency button. Once the monitoring center receives a distress order, the monitoring center staff can provide assistance or notify the police for assistance.

(4) Historical track playback function

In the historical track playback, the GPS positioning system can check where the vehicle, person or pet is located on a certain day in the historical information, and which route is taken. What is the state of the vehicle at that time, etc.
