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...

Arrival query module of auto parts information management system

 

Arrival inquiry can be inquired by product number, product name, unit number, unit name and arrival date. Inventory management module This module completes the inquiry of inventory, mainly including inquiry by voucher number, inquiry by product number and inquiry by product name. Sales Management Module This module is composed of three independent modules: product sales, sales order query, and sales detail general ledger. It can input, query, statistical analysis and report printing of sales data. Product sales perform sales data entry, printing receipts and other tasks.

Sales Order Inquiry Complete inquiry of previous sales orders, you can inquire by customer number and customer name. The sales details general ledger queries and displays the sales status of all commodities, and can also display the sales status of a certain commodity. The customer management module manages all suppliers and users, including 4 sub-modules: supplier files, user files, supplier information and user information modules. The provider file module enters, modifies and queries the provider records. The user profile module enters, modifies and queries user records. The offerer information module browses for arrivals, additional payments, and additional payments for the offerers. The user information module allows users to browse sales, additional payments, and additional payments.

Return processing module The main function of this module is to query the return status of all users and suppliers, including the supplier return module and the user module. Out-of-stock processing module The main function of this module is to inquire and print the goods below the minimum storage capacity, so as to purchase goods in time. Print module This module completes the printing of commodity quotations, year-end inventory lists, warehousing lists, sales detailed lists, inventory shortage status lists, and annual and monthly reports.
