CNC Machining to promote industrial development

图片
With the continuous improvement of technology, all countries around the world have also realized the supportive position of using precision . CNC Machining  for the development of the whole industry. In order to deal with the international financial crisis, All of them have to adjust their industrial policies of precision machining of CNC machine tools, The development of high-end CNC machine tools to promote the development of precision machining industry I will always share some knowledge about  Precision Machining  etc.If you like my share,welcome to follow me and hope to get your suggestions.

How To Draw The Drawings of CNC Machined Components?

图片
As long as you know CAD, a  CNC Machined Component  to draw three figure on a piece of paper: main view, from the top part of the figure, the left view. Generally simple parts painting these three paintings can be expressed clearly, like the gear axis and so on. The complex structure needs to draw the sectional view, partial enlargement map. Open the part and express it internal structure and size clearly, such as screw hole, gear box and so on. If you want to know more about how to draw, you should see more about the CNC machined parts drawings.  Precision Machined Parts  also have their own standardized production, such as screw length, diameter and so on. So that once the machine fails, it is easy to repair. 

What Is CNC Machined Component?

The definition of  CNC Machined Component  is: 1.Component is a single component that can not be split. 2.Part: combination of parts that perform an action or function. A part can be a component or a combination of multiple parts. In this combination, a part is the main part, it realizes the fixed action, and other parts only play the auxiliary role such as connection, fastening and guiding. 3.Parts and components in ordinary cases, all parts except the frame are called parts.  As for the casting and forging parts, it is the classification of the manufacturing methods of the parts. Different materials and manufacturing methods make the parts has different mechanical properties. They are different concept with parts.

Common Workpiece Defects and Causes in CNC Turning

Bend:  1.The weight of the material and its own bending. It should be treated by straightening and hot province. 2.The workpiece clamping is not good, tailstock and the center hole is tight. 3.The improper selection of the geometric parameters and the cutting parameters of the  CNC Turning , result to cutting force is too large. You can reduce the cutting depth and increase feed number. 4.Hot deformation is produced in cutting. Cooling lubricants should be used. 5.The distance between the tip and the support block is too large. It should not exceed 2mm. Surface of  CNC Turned Component  is rough: 1.The vibration of the turning. 2.Improper selection of material with the support block of the tool, bad contact with the workpiece and friction. 3.The improper selection of the geometric parameters of the tool.

What Are The Methods To Get The CNC Machining Accuracy?

China CNC Machining  accuracy is mainly reflected in the following aspects: size accuracy, geometry precision and mutual position precision, which includes geometrical precision roundness, straightness and flatness. Mutual position precision including parallelism and perpendicularity and concentricity etc. What are the methods to get the CNC machining accuracy?  Dimensional precision: the main methods such as test cutting, adjusting method, fixed size method and automatic control method.  Geometrical shape precision: the method of trajectory method, forming method and development method and so on. Mutual position precision: the main methods are direct installation method, positive and fixture installation method and so on. JST supply high quality  Precision Machined Components  with best price. Welcome to contact or visit us.

Heat Treatment of CNC Machining Process

图片
Heat treatment of  CNC Machined Components  process can be divided into two kinds: preparation heat treatment and final heat treatment.  Preparatory heat treatment is to improve mechanical properties and eliminate internal stress, so as to prepare for final heat treatment. Generally including annealing, normalizing, quenching and tempering and aging treatment. The preparation heat treatment is usually after rough processing.  Final heat treatment: is to improve the hardness and wear resistance of parts, including quenching, carburizing, nitriding and so on. Usually carried out after semi-finishing and before finishing. JST supply the best  China CNC Machining  service for many years, welcome to contact us freely for more requirements: info@jstindustry.com.

Matters Need To Pay Attention To in Precision Machining

1.In order to ensure  Precision Machining  accuracy, coarse and fine processing should be carried out separately. If the coarse and fine processing machining is continuous, fine machining  Precision Machined Parts  accuracy will be lose quickly due to the re distribution of stress. For some parts with high processing precision, before and after rough processing, low temperature annealing or aging treatment should be arranged to eliminate internal stress. 2.Reasonable selection of equipment. Rough machining should be carried out on machine tools with large power and low accuracy. Fine machining requires higher accuracy machine tools. Reasonable equipment can not only give full play to equipment capacity, but also prolong the service life of precision machine tools. 3.Heat treatment process is often arranged in the machining process. 

JST Supply Good CNC Machining Service

CNC is the main equipment for making hand panels. The way of processing is to excavate all kinds of metal materials such as aluminum, copper and stainless steel into the physical samples we need. The sample produced by CNC machining has the advantages of large size, high strength, good toughness, low cost and so on. It has become the mainstream of hand plate production.  Injection Molding  is a tool for producing plastic products and give the complete structure and exact size. Injection molding is processing method used in the mass production of some complex shape parts. Concretely refers to the heated material into the cavity by high pressure, after cooling and curing, the material will be formed. JST supply good  CNC Machining Service  and other casting, plastic injection mold service. 

Do You Know China CNC Machining Advantages?

Improving  CNC Machining  accuracy is possible from the following aspects of controlling temperature: 1.Carefully choose whether the machine tool conforms to international standard ISO230-2 and national standard GB 10931-89. 2.The components of the lathe control sliding bearings, in order to ensure the good bearing of the project, it guarantees the machine dynamic accuracy. 3.As a heat source, as far as possible to leave the machine spindle. Heat dissipation is also enhanced, lubricated with metalworking fluids. In addition, CNC processing steps are more, need consider the integrity problem automobile,  CNC Milling , turning, drill, grinding , cutting fluid and so on.

What Is the Technology Characteristics of Automatic Lathe Machining?

Automatic Lathe Machining  is a part of mechanical processing, there are two main forms, one is the processing of the workpiece is not fixed form tool machining rotary, the other is the workpiece is fixed, through the high speed rotation, tool of the horizontal and vertical movement of the  Precision Machining . 1.It is easy to ensure the accuracy of each workpiece surface. When machining, the workpiece revolves around a fixed axis, each surface has the same rotating axix. 2.The cutting process is relatively smooth, in addition to the intermittent surface, in general, the automatic lathe machining process is continuous. 3.It is suitable for non-ferrous metal parts finishing.  4.The tool is simple, turning tool is the simplest tool, manufacturing, grinding and installation are convenient, it is convenient to choose a reasonable angle according to the specific processing requirements.
