What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

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

HOW TO CUSTOM HELMET

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.

Tools/raw materials: Polycarbonate material Composite material
 
Method/Step
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.
