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

Selection of Surface Machining Methods for Inner Hole of CNC Lathe Machined Parts

Selection of Surface Machining Methods for Inner Hole of CNC Lathe Machined Parts

 

There are many methods for surface processing of inner holes of CNC lathes. Commonly used are drilling, reaming, reaming, boring, turning, grinding, drawing, grinding, honing, and rolling holes.

 

Applicable method for inner hole machining of CNC lathe machined parts:

 

1. Drilling:

Drilling holes in the solid part of the workpiece with a drill is called drilling. CNC cutting is a process method for parts processing on CNC machine tools. The process regulations of CNC machine tool processing and traditional machine tool processing are generally the same, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batches, complex shapes, and high precision, and to achieve high-efficiency and automated processing. The drilling is rough swiss machining, and the dimensional tolerance level that can be reached is IT13~IT11, and the surface roughness value is Ra50~12.5μm. Is it due to the long length of the twist drill, the small core diameter and poor rigidity, as well as the influence of the chisel edge.

 

2. Reaming:

Reaming is a finishing method for holes on the basis of semi-finishing (reaming or semi-finishing boring). 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 letters, and the processing required by the processing technology. It generally refers to the process of processing parts on CNC machine tools. In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC machining, a series of advanced CNC drilling technologies have been developed and used in the aerospace industry. The size tolerance of the reaming hole can reach IT9~IT6, and the surface roughness value can be Ra3.2~0.2μm. There are two ways of reaming: organic hinge and hand hinge. Reaming on a machine tool is called a machine hinge, and a manual reaming is called a hand hinge.

 

3. Car hole:

The turning hole on the lathe is the rotation of the workpiece and the movement of the turning tool. The aperture size can be controlled by the cutting depth of the turning tool and the number of passes, which makes the operation more convenient. 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 letters, and the processing required by the processing technology. It generally refers to the process of processing parts on CNC machine tools. In order to improve the degree of production automation, shorten the programming time and reduce the cost of CNC mill-turn, a series of advanced CNC machining technologies have been developed and used in the aerospace industry. Lathe turning holes are mostly used to process the holes of disc sleeves and small brackets.

 

4. Boring:

Boring is the further processing of holes that have been drilled, cast or forged with a boring tool. It can be carried out on a lathe, boring machine or milling machine. Boring is one of the commonly used hole processing methods, which can be divided into rough boring, semi-fine boring and fine boring. The dimensional tolerance grade of rough boring is IT13~IT12, and the surface roughness value is Ra12.5~6.3μm; the dimensional tolerance grade of semi-finish boring is IT10~IT9, and the surface roughness value is Ra6.3~3.2μm; The dimensional tolerance grade is IT8~IT7, and the surface roughness value is Ra1.6~0.8μm. here is about our partner.

 

5. Reaming:

Reaming is to use a reaming drill to further process the drilled hole to enlarge the aperture and improve the accuracy (precision) and reduce the surface roughness value. The dimensional tolerance level that can be achieved by reaming is IT11~IT10, and the surface roughness value is Ra12.5~6.3μm. It belongs to the semi-finishing method of hole processing. It is often used as pre-processing before reaming, and can also be used as precision (precision). The final machining of holes that are not high.
