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

Plastic materials and their characteristics

      Plastic materials refer to materials that use polymer synthetic resin as the main component, have plasticity and fluidity at a certain temperature and pressure, can be molded into a certain shape, and keep the shape unchanged under certain conditions. Commonly used plastic materials are divided into thermosetting plastic materials and thermoplastic plastic materials. Thermosetting plastic materials are characterized by being able to solidify into insoluble materials under heat or other conditions. Thermoplastic materials are characterized by repeated heating to soften or cooling to solidify within a specific temperature range. In terms of performance, plastic machining service have the advantages of light weight, good strength, corrosion resistance, good insulation, easy coloring, products can be processed into any shape, high production efficiency, and low price.

      The versatility of the application of plastic materials is inseparable from its own characteristics. The composition characteristics of plastic materials are introduced below.

(1) Molecular structure of plastic materials

The main component of plastic machining  is resin. There are two types of resin, natural resin and synthetic resin.



(2) Composition of plastic materials

Resin: The main function is to bond other components of the plastic material and determine the main properties of the plastic material, such as mechanical, physical, electrical, and chemical properties. The proportion of resin in plastic materials is generally 40% to 65%.

Filler: also known as filler. Correct choice of filler can improve the performance of the plastic material and expand its scope of use.

Plasticizer: Some resins have very little plasticity and poor flexibility. In order to reduce the melt viscosity and melting temperature of the resin, improve its molding processing performance, improve the flexibility, elasticity and other necessary properties of plastic materials, usually Add a non-volatile high-boiling organic compound that is compatible with the resin. Such substances are called plasticizers.

Coloring agent: also known as coloring material, mainly for aesthetics and decoration, including paint part.

Stabilizer: Any substance that can delay the deterioration of plastic materials is called stabilizer, light stabilizer, heat stabilizer and antioxidant.

Lubricant: improve the fluidity of plastic material melt, reduce or avoid friction and adhesion to equipment or molds, and improve the surface finish of Plastic Machining Parts.
