What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

What is the content of forging quality inspection?

    The existence of forging defects may affect the processing quality or processing quality of the subsequent processes, and some seriously affect the performance and use of the forgings, and even greatly reduce the service life of the finished parts and endanger safety. Therefore, in order to ensure or improve the quality of cold forgings, in addition to strengthening quality control in the process and taking corresponding measures to prevent the occurrence of forging defects, necessary quality inspections should also be carried out to prevent subsequent processes (such as heat treatment, surface treatment, cold processing, etc.). ) And forgings with defects that have adverse effects on performance will flow into the subsequent process. After quality inspection, remedial measures can be taken on the forgings made according to the nature of the defect and the degree of influence to use, so that it meets the technical standards or requirements for use. Therefore, in a sense, the quality inspection of forgings, on the one hand, is to check the quality of the forgings that have been made, and on the other hand, to point out the improvement direction for the forging process, so as to ensure that the quality of forgings meets the requirements of forging technical standards and meets the design Requirements on processing and use.

 

Forging

  The quality inspection of hot forgings includes the inspection of appearance quality and internal quality. Appearance quality inspection mainly refers to the inspection of the geometric size, shape, surface condition and other items of the forging; the internal quality inspection mainly refers to the inspection of various items such as the chemical composition, macrostructure, microstructure and mechanical properties of the forging. Specifically, the appearance quality inspection of forgings is to check whether the shape and geometric dimensions of the forgings meet the specifications of the drawings, whether the forgings have defects on the surface, what kind of defects are they, and what are their morphological characteristics. The inspection content of the surface condition is generally to check whether the forging surface has surface cracks, folds, wrinkles, pits, orange peel, blisters, scars, corrosion pits, bruises, foreign objects, underfill, pits, lack of meat, Defects such as scratches. The internal quality inspection is to check the internal quality of the forging itself. It is a quality condition that cannot be found by the appearance quality inspection. It includes the inspection of the internal defects of the forgings and the inspection of the mechanical properties of the forgings. Parts or large metal forgings should also be subjected to chemical composition analysis.

 

Forging

  For internal defects, we will use low-power inspection, fracture inspection, and high-power inspection to inspect the forgings for the presence of internal cracks, shrinkage holes, porosity, coarse crystals, white spots, dendrites, and streamlines that do not conform to the shape, Defects such as streamline turbulence, penetrating flow, coarse crystal ring, oxide film, delamination, overheating, overburning organization, etc. For the mechanical properties, it is mainly to check the normal temperature tensile strength, plasticity, toughness, hardness, fatigue strength, high temperature instantaneous rupture strength, high temperature permanent strength, permanent plasticity and high temperature creep strength.

  After the forgings are produced into rigging, their stress conditions, importance, and working conditions are different during use, and the materials and metallurgical forging used are also different. Therefore, different departments will classify forgings according to the above conditions and the requirements of the department. , Different departments and different standards have different classifications of forgings.
