How Do CNC Machines Work? 1. CNC machining starts with a computer, on which designers prepare a part using CAD (Computer-aided Design) software. This digital part is then converted into a format that can be recognized by a CNC machine. 2. Instructions are sent to the CNC machine in the form of “G-Code” after which the machine can start cutting. 3. Most CNC machines have a “worktable” and work holding device to
CNC is the abbreviation of computer numerical control, usually using computer control and machine tools to remove the material layer from the blank to produce custom-designed parts. The process is suitable for various materials, including metal, plastic, wood, glass, foam, and composite materials, and is widely used in various industries. Compared with additive manufacturing processes (such as 3D printing) or molding manufacturing processes (such as liquid injection molding), CNC machining usually uses a subtractive manufacturing process. The subtractive process removes layers of material from the workpiece to produce customized shapes and designs, the additive process assembles the layers of material to produce the desired shape, and the forming process deforms and shifts the raw material to produce the desired shape. CNC machining has the characteristics of automation, which can achieve high precision and cost-effectiveness in one-off and mid-batch production. Of course, each type of manufacturing process has its advantages and disadvantages, but this article focuses on the basic knowledge of CNC processing, as well as various components and tools of CNC processing. In addition, this article discusses various operations of CNC machining and proposes alternative methods for CNC machining. Although CNC machining provides various functions and operations, the basic principles of the process are basically the same. The basic process of CNC machining includes the following stages: CAD model design Convert CAD files to CNC programs Prepare CNC machine tools Perform processing operations Next in detail: CAD model design The CNC machining process starts with the CAD design of 2D vector or 3D solid parts internally
Can Titanium Be CNC Machined? Titanium alloy refers to a variety of alloy metals made of titanium and other metals. Titanium is an important metal developed in the 1950s, it has high strength, good corrosion resistance and high heat resistance. A number of corrosion-resistant titanium alloys were developed in the 1970s. Since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been developed. Titanium alloy can be CNC machined same as stainless steel and it is mainly used to make aircraft engine compressor parts, rockets, missiles and high-speed rail structural parts. Because of its excellent properties, titanium alloy will inevitably replace steel as the most important metal material in the future. In real life, titanium alloy products are still particularly expensive. What caused the problem? Titanium alloy raw materials are expensive, but it is still acceptable. The main reason is that the machining processing of Titanium is high cost. This is caused by the properties of titanium which is high strength and high toughness make it difficult to be machined, and the production efficiency is very low. The current level of machining technology level to machine titanium would be very high costs. If you expect to use it cheaply and widely used, that must improve the efficiency and speed of titanium alloy production and processing step by step. Is titanium metal expensive? Why Apple doesn’t apply the lighter and stronger titanium alloy for iPhone? Apple had a Titanium Power Book G4 made of titanium alloy in 2001, but later
Discussion On The Characteristics Of Titanium Alloy And The Method Of CNC Machining Titanium Alloy The various properties of titanium make it an attractive material for parts, but many of its properties also affect its machinability. What are the attributes of titanium alloys, what are the characteristics of titanium alloy processing, what problems should be paid attention to when processing titanium alloys, what methods are there when processing titanium alloys, and how to choose a good titanium alloy processing manufacturer? The details are described below. Properties of titanium alloy Titanium has an excellent strength-to-weight ratio, and its density is usually only 60% of steel. Titanium has a lower coefficient of elasticity than steel, so it has a harder texture and better deflection. The corrosion resistance of titanium is also better than that of stainless steel, and its thermal conductivity is low. These properties mean that titanium will produce higher and more concentrated cutting forces during processing. Titanium alloys are prone to vibrations that can cause chattering during cutting, and they are also prone to react with cutting tool materials during cutting, thereby exacerbating crater wear. In addition, titanium alloys have poor thermal conductivity. Since the heat is mainly concentrated in the cutting area, the tools used for titanium alloy parts processing must be high hardness and high heat resistance. The characteristics of titanium alloy processing In actual processing, it is not easy to meet all the conditions required for processing titanium alloy parts, because ideal stable conditions are not always available.
The advantages of CNC machining versus 3D printing 3D printing and CNC machining are relatively common production processes in the field of precision machining. There are similarities and differences between them. For example, CNC machining is suitable for mass production. It can create many products in a shorter period of time, and 3D printing takes hours to create a product. Compared with 3D printing, what advantages does CNC machining have? The main points are as follows: CNC machining advantages of surface treatment CNC machining provides a better surface finish than 3D printing because the material will not be deformed during processing. The rigid material and cutting action keep the product together, and there is less chance of error or deformation. The surface finish of 3D printing is poor. The material is bent or twisted because the material is layered to heat the plastic. CNC machining prototype integrity is improved CNC machining does not need to heat the material and modify it. Compared with 3D printing, the material remains stronger and has better structural integrity. 3D printing must heat the material to build the desired product. 3D printing may also require the addition of foreign matter to the mixture to make a prototype, while CNC machining does not. CNC machining prototyping becomes easier CNC machining is more suitable for prototypes that can withstand structural testing because they engrave designs from materials. They can also build prototypes using the exact materials that will be used to make the final product. Structural tests
How to Improve The Surface Quality of the CNC Processing Products CNC machining can solve the processing problems of some large and small batches in industrial production. Some precision parts can also be completed by CNC machining centers, but this raises the requirements for the surface quality of parts. How can we improve the surface quality of CNC machined parts during actual operation? Reasonably design cutting-in and cutting-out routes When using a CNC machining center for parts processing, it is necessary to optimize the design of the cutting-in and cutting-out routes to optimize the cutting angle of the machine tool. In order to achieve the effect of reducing the marks of the cutter and ensuring that the quality of the surface is not affected, it is necessary to optimize the cutting of the cutter. The cutting point of the tool mainly starts from the periphery of the part, so as to ensure a smooth contour surface. Try to choose a smaller feed rate for the cutting tool, let it keep cutting at a slow speed, so that the cutting transition smoothly, so as to ensure the cutting quality. Correctly choose the cutting method When using a CNC milling machine for processing, there are two ways of down milling and up milling. The finishing effect of down milling is better than that of up milling. Therefore, when processing parts, try to choose down milling to improve the surface quality of parts when conditions permit. When turning shaft parts, it is necessary to select the same turning
CNC Plastic Machining for Prototype sample Nowadays, CNC plastic machining processing is mostly used for prototype sample. CNC prototype processing is a method of cutting off the excess material in the whole block material by the removal method. In the prototype processing industry, CNC prototype processing is generally aimed at large workpieces, prototypes that require relatively high precision and appearance requirements. So what is the reason for choosing CNC prototype processing? Let’s talk about the advantages of CNC plasitc machining prototype model? CNC machining can process a wide range of plastic materials CNC Machinable materials include ABS, POM, PC, acrylic (transparent material) stainless steel, aluminum alloy, H62 brass, Q235 iron, etc. The main plastic material for CNC plastic machining of prototype sample is: 1. ABS prototype: temperature resistance: 60-80℃/characteristics: excellent strength and resistance/wide range of application: this material is mostly used for shell prototypes such as electrical appliances, medical treatment, and cars. 2. PMMA acrylic hand plate: temperature resistance: 60-80℃/characteristics: high transparency/applicable scope: electric liquid crystal shell hand plate. 3. POM hand plate: temperature resistance: 90-110℃/characteristics: strength, resistance, good hardness/applicable scope: mechanical gear, rotating parts hand plate. Wide range of application areas for CNC plastic machining of prototype CNC plastic prototype processing is often used for prototypes for cars, medical care, aerospace, planning, small household appliances and computer peripheral products, as well as large-scale products such as air conditioners, monitors, audio, medical equipment, motorcycles, car accessories and other products. CNC prototype model also has many advantages 1. The CNC prototype
CNC MACHINING Of Hardware Hardware should be very extensive in industrial production and manufacturing. Generally, most of the hardware is manufactured by CNC processing. It is necessary for us to have a detailed understanding of the CNC processing of the hardware. At the same time, through the familiarity with the hardware Processing, we will also understand the CNC processing process of other products. Introduced in several parts: Process of precision hardware processing Rough machining stage Most of the machining allowance of each metal processing surface is cut off, and the machining accuracy benchmark is mainly to increase productivity as much as possible. Semi-finishing stage In order to prepare for surface finishing, it is required to achieve a certain machining accuracy, ensure proper finishing allowance, and complete secondary surface processing at the same time. Fine finishing stage At this stage, use high cutting speed, small feed speed and depth of cut to cut off the finishing allowance left by the previous process, so that the surface of the part meets the technical requirements of the drawing. Finishing processing It is mainly used to reduce the surface roughness or strengthen the processed surface, and is mainly used for surface processing with high surface roughness requirements (ra≤0.32μm). Ultra-precision processing The machining accuracy is between 0.1-0.01 microns, and the surface roughness value ra≤0.001μm. The main processing methods are: precision cutting, mirror finish grinding, precision grinding and polishing, etc. The method of surface treatment of hardware processing Hardware processing processes raw materials in accordance with
What Causes Errors in CNC Machining Precision plays an extraordinary role in the CNC Machining process, especially now that many precision parts require extremely high precision in CNC machining. However, there will be many errors in the CNC machining process. If these errors cannot be dealt with in a timely and effective manner, it is obvious that the CNC processed products will not meet the standards. Today, 3QMachining will analyze the causes of errors in CNC machining for everyone, so as to help you quickly find out the cause and solve the error problem. CNC Machining positioning error The reference point does not overlap the deviation The standard used to confirm a certain surface layer specification and specific location on the part drawing is called the design concept standard. The standard used in the process flow chart to confirm the specifications and specific positions of the processed surface layer of the process flow is called the process flow standard. When carrying out finishing machining on steel parts on CNC Machining processing, it is necessary to select a number of basic geometrical elements on the steel parts as precise positioning datum during finishing. If the precise positioning datum used does not overlap with the design plan datum, it will cause The standard does not overlap the deviation. CNC machining accurately locates the deviation of inaccurate production and manufacturing The components on the fixture are difficult to be produced with absolute accuracy according to the basic specifications, and their actual specifications (or specific
What Is a CNC Router CNC Router is a computer numerical control (CNC) which is one kind of CNC Machinery but different CNC Milling and CNC Turning, CNC router machine with small tools is good at machining precision and small/tiny parts, with the ability of milling, grinding, drilling and high-speed tapping. It is widely used in 3C industry, mold industry, medical industry and other fields. A computer-controlled cutting machine which typically mounts a hand-held router as a spindle which is used for cutting various materials, such as wood, composites, aluminium, steel, plastics, glass, and foams. CNC routers can perform the tasks of many carpentry shop machines such as the panel saw, the spindle moulder, and the boring machine. They can also cut joinery such as mortises and tenons. A CNC router is very similar in concept to a CNC milling machine. Instead of routing by hand, tool paths are controlled via computer numerical control. The CNC router is one of many kinds of tools that have CNC variants. What is a CNC router used for? Due to the development and demand of the electronic consumer market in the future, more digital electronic displays use glass as display screens or touch screens, and the market for CNC router machines is also growing.

Mobile phone capacitive screen contact control board, resistive screen base molding processing; 3. PC, acrylic, Cutting and chamfering of
How long does 3D printing take? 3D printing is a form of add-on or additive manufacturing technique which is totally different from CNC Machining (a reduce material manufacturing technique). It makes custom parts being produced layer by layer with substances such as plastic or metal powders, plastic filaments or resins. Its energy source is either a laser or a heated extruder which creates decks or layers of these materials by solidifying them to finally form the finished part. The joy of 3D printing is in your ability to create freedom of shape, its accuracy, speed, and its ability to cut on costs and to decrease the weight of certain parts. When you want to create a product part with 3D Printing, you will want to know hot long does it take to finish it, let’s have a close look at the 3D printing to find out the major elements to affect the timing to do with 3D Printing, it would be easily accessible than you may think. 01. Part size Bigger size part means more material and need more time to do printing by 3D Printer. For example, if your 3D printer can print each layer with 25μm and takes 20s for each layer, then you can calculate the whole time it would take to finish 3D printing. 02. Part structure complexity More complex structure part means its whole area & volume is bigger than a simple structure part even their whole size is same, that means a complex structure
