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

Why are outdoor titanium products so popular?

Titanium has a lower density than conventional stainless steel. A 550 ml titanium kettle weighs only 99 grams, and the quality of a stainless steel bottle of the same size is about twice that of a pure titanium bottle. Lighter devices usually mean higher efficiency on the move. Applying pure titanium products to outdoor activities can significantly reduce the burden on passengers. Pure titanium is extremely durable and is comparable to stainless steel, which is far superior to the same lightweight aluminum products. Climbing is inevitable and the kettle remains, even if it falls on a stone. In special cases, a pure titanium kettle can even serve as an emergency aid.

Outdoor titanium products

The surface of pure titanium products has a dense oxide film. Well adapted to various environments at room temperature. Therefore, no spray is required. Pure titanium kettle has excellent corrosion resistance. In outdoor weak acid or weakly alkaline environments, pure titanium kettles can also cope with it, and in rivers, rain, rocks and vegetation, pure titanium kettles can be brought into direct contact without corrosion. Since the whole body of the kettle is unpainted, the kettle has a unique gray color of pure titanium products and can also be heated directly at the source of the fire.

Pure titanium kettle

For example, the kettle lid is made of pure titanium and rubber. Pure titanium caps have better performance in terms of corrosion resistance and product health. Pure titanium products are completely harmless to the human body, so you can use pure titanium containers to heat water and food. The pure titanium cover does not have a heat insulating function and is suitable for outdoor use.

The pure titanium belt weighs about 109 grams. A stainless steel belt of the same size weighs about 1.5 times as much as a pure titanium belt. Titanium belts are made of high density nylon wire with light weight, high strength, soft touch and good wear resistance properties.
