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

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

Elimination of Gear Backlash in CNC Machining Feed System

Elimination of Gear Backlash in CNC Machining Feed System   The transmission gear in the feed system of the CNC machining machine tool must eliminate the transmission gap between the meshing gears as much as possible, otherwise the motion will lag behind the command signal after each reversal of the feed system, which will affect the machining accuracy (accuracy) ). There are the following two common methods for CNC machining machine tools to eliminate the transmission gear gap.   1. Rigidity adjustment method   The rigid adjustment method is an adjustment method that cannot be automatically compensated for the tooth side clearance after adjustment. Therefore, the pitch tolerance and tooth thickness of the gear must be strictly controlled, otherwise the flexibility of the transmission will be affected. This adjustment method has a relatively simple structure and a better transmission rigidity.   (1) Eccentric shaft adjustment method   As shown in Figure 610, the gear 1 is mounted on th

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.
