The paper format can be divided into 5 types according to size, and the drawing format codes are A0, A1, A2, A3 and A4 respectively. There must be a title bar at the lower right corner of the frame, and the text direction in the title bar is consistent with the viewing direction. The types of d

High Speed Steel High speed steel (HSS) is a kind of tool steel with high hardness, high wear resistance and high heat resistance, also known as wind steel or front steel, which means that it can harden even when cooled in air during quenching, and it is very sharp. Also known as white steel. Hi

3D files have changed the way engineers work with manufacturers. Engineers can now design parts using CAD software, send digital files to manufacturers, and have manufacturers manufacture parts directly from the files using digital manufacturing techniques such as CNC machining. But while digita

1. Differences In Materials 3D printing materials mainly include liquid resin (SLA), nylon powder (SLS), metal powder (SLM), gypsum powder (full color printing), sandstone powder (full color printing), wire (DFM), plate (LOM), etc. Liquid resins, nylon powders, and metal powders account for the

Now, many CAD/CAM software packages provide automatic programming functions. These software generally prompt the related issues of process planning in the programming interface, such as tool selection, machining path planning, cutting amount setting, etc. The programmer only needs to set the rel

During vibration cutting, the cutting force is small, the cutting temperature is low, the cooling is sufficient, and the chips are easier to break and discharge, which can significantly extend the tool life of precision mechanical parts processing. If the vibration parameters are properly select

For prototype and end-use parts, accuracy is a very important aspect of metalworking. Accuracy means you get a part that looks and feels exactly as you designed it, with no errors that could affect mechanical function. Thanks to the rise of CNC machines, metalworking is now more precise tha

There are three kinds of compensations in CNC machining: these three kinds of compensations can basically solve the trajectory problem caused by the shape of the tool during machining. The following is the application of three kinds of compensation in general machining programming. Tool Length C

Tool Radius Compensation 1. The concept of tool radius compensation The CNC machining center regards the tool as a point to make trajectory movement when the program is running. For example, when using tool R3 to mill a square boss with a side length of 100, the program is input in the size of a

Fixtures are an indispensable part of CNC machining centers. Each CNC machining center will use fixtures, and according to different products to be processed, the fixtures used are also different, and the requirements for fixtures are also different. The requirements of the fixture are similar,

During the machining process of the CNC machining center, whether the selection of the positioning datum is reasonable or not determines the quality of the parts, which has a great influence on whether the dimensional accuracy and mutual orientation accuracy requirements of the parts can be guar

Use the right kind of thread to make it simple and reliable. Therefore, it is important to understand the various threads used to install connections. There are two main types of threads, parallel threads and tapered threads. Parallel threads have parallel profiles, maintaining the same diameter

The ease of cutting metal with a cutting tool is called machinability. However, it is difficult to quantify this characteristic due to the many factors that determine the machinability of metals. This article introduces the basics of machinability: what it is, factors influencing machinability,

Galvanizing is one of the most widely used methods of protecting metals from corrosion. It coats the metal with a thin zinc coating that helps isolate it from its surroundings. Quite simply, galvanizing the metal gives it anti-corrosion properties. Without a protective zinc coating, the metal wi

To change the properties of the steel and make the steel easier to machine, additional treatments and processes are usually done before machining is complete. Hardening the material before machining increases machining time and increases tool wear, but steel can be treated after machining to inc

The machine is a very important production technology equipment in the processing and production of mechanical products. Therefore, when analyzing the structural design of the machine tool fixture, it must be based on the processing requirements of the workpiece and the positioning that the ente

What Is Parallelism in GD&T? GD&T Parallelism Symbol There are two types of Parallelism in GD&T. It can refer to surface parallelism or axis parallelism, depending on whether you are using it to control a surface or an axis. The use of surface parallelism is more common than axis pa

Problems In The Process Of CNC Machining Of Thin-walled Parts (1) Problems in the machining process The CNC machining process of thin-walled parts requires that the thickness of the entire part does not exceed 1mm. Although the overall structure of thin-walled parts is relatively compact, t

Before machining in the machining center, please use the calibrator to check whether the CNC blade shakes within the allowable dimensional tolerance. Before machining, use a hot air gun to clean the blade and lock the nozzle, or scrub the cloth to install the tool. The flow chart specification

What Is Symmetry? GD&T symmetry is a 3D tolerance that ensures that part features are symmetrical about the datum plane. The dimension defines a center plane and creates a tolerance zone around it. This tolerance is similar to concentricity, and the verification of symmetry tolerance is also
