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

Influence of 3D printing on mechanical manufacturing and automation

Influence of 3D printing on mechanical manufacturing and automation

3D printing technology is widely used because of its flexibility and convenience. Printing technology involves different molding processes and material classification.

There is no uniform standard now. According to the volume of the equipment, it can be divided into desktop, medium and large 3D printers; It can be divided into: aerospace, military, industrial, civil 3D printers, etc. 3D printing propsis a comprehensive technology combining mechanical engineering technology, computer software technology, 3D model technology, data processing technology and other disciplines. To a certain extent, it meets the needs of the development of mechanical manufacturing, and brings ultra-fast molding speed, unparalleled printing speed, high material utilization rate and short production cycle in industrial production, greatly improving the degree of automation and digitalization.

At present, XYZPrinting partpro150_ XP, mechanical manufacturing and automation are mainly based on computers, combined with mechanical equipment and automation, and through a series of manufacturing technologies, such as computer-aided design and manufacturing, flexible manufacturing system, and then constitute a computer integrated manufacturing system. Its applications mainly include CNC machines and machining centers.

The impact of printing on mechanical manufacturing and automation mainly has two aspects: positive and negative.

It has two impacts on the development of mechanical manufacturing and automation. 3D printing medical uses a variety of materials, but the material itself has limitations and hazards. Especially, the more difficult it is to degrade materials, which directly threatens human health and safety. The promotion of 3D printing and laser scanning technology may also lead to a large number of imitation products, which will bring some challenges to the development of the design industry and commodity costs, such as furniture products, tools, and even intellectual property issues.

In the information age, printing in chip manufacturing still has some limitations. Because the relevant parts of different materials are difficult, it is necessary to improve and improve between energy consumption, high cost and low efficiency. 3D Printing jewellery is an important embodiment and component of the development of mechanical manufacturing automation.

Compared with traditional printers, the liquid or powder emitted by 3D printers are different printing materials, such as light curing, rapid direct manufacturing and molding, layer-by-layer control computer superposition, and finally the physical object can be obtained. The workflow of 3D printer is to create a project, use CAD software, copy the model to 3 printers, print by setting various adjustable parameters, and specifically compose control elements, mechanical elements, print heads, consumables and media If all processes and parts are automated, 3D printing technology and mechanical manufacturing automation will be more closely linked.
