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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

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


All speed-related sports require a helmet. Classified according to human body parts the helmet is the first life-saving equipment. There are many types of helmets, different sports, different uses and different shapes, half helmets, full helmets, face helmets, cross-country helmets and so on. However, in terms of manufacturing procedures, they are basically the same. Knowing how the helmet is made can better enable us to purchase and use the helmet.
Custom Bicycle Helmet
Tools/raw materials: Polycarbonate material Composite material
Making EPS (expandable polyethylene) helmet lining: why choose EPS? There are three main points, which are cheap, light and easy to use.  It's amazing; this kind of foaming material that can be used to make lunch boxes is a good head protection material. In fact, one of the differences between an ordinary helmet and a high-quality helmet is the quality of polyethylene. For example, some helmet manufacturers use the same polyethylene propylene material to make the entire lining, while others develop polyethylene lining with different thickness, strength and shape specifically for the purpose and shape. The latter means that each helmet must have its own mold and CAD design, which of course means cost.

How to make a helmet
Make a polycarbonate helmet shell. The resin is injected into the helmet shell mold machine in a liquid state, and is formed by extrusion of the child and mother molds. Each helmet mold is also designed with CAD/CAM models for different sizes. The molds used to manufacture helmets have a life cycle, and each time a new helmet is launched, a batch of molds will be eliminated. From injection to molding, each helmet mold takes about 60 seconds, after which it enters the next step, grinding, spraying, and decals. Then install the mask, and perform anti-scratch and anti-fog treatment on the mask.
Polishing, painting and carving treatment. One advantage of the polycarbonate helmet is that once the mold is completed, the mask and other moving parts can be directly installed, because all hole positions of the polycarbonate helmet are reserved during the molding process, and no subsequent drilling is required. Some manufacturers use mechanized processes in the helmet polishing process, while others maintain manual processing. After the surface is treated, the helmet will be painted and decals. The decals are designed and printed by the computer, and finished by manual. Finally, a helmet is basically finished by polishing.
Assemble, pack and ship. After the appearance-treated helmet, various required parts, visors, face masks, etc. will be installed. At the same time, the final quality inspection of the staff will be accepted during this process, including thickness inspection of various parts, impact test sampling, etc., and finally packaging and transportation, We can buy it on the market.
