What are the characteristics of CNC machining?

1. Increase productivity

CNC machine tools can shorten the production preparation time and increase the ratio of cutting processing time. The use of digital control means can control complex curved surfaces, and the processing process is controlled by computer, and the interchangeability of parts is strong. And adopt the best cutting parameters and the best route to achieve the purpose of shortening the processing time, thereby improving production efficiency.

2. Stable product quality

CNC machine tools can improve the machining accuracy of parts. The main reason is that it is processed automatically according to the program, without any intervention, and its machining accuracy can also be corrected and compensated by software, so it can obtain higher machining accuracy and repeatability than the machine tool itself.

Strong flexibility

By changing the program, the machine has a wide range of practicality and flexibility. When machining parts of new products, it can complete the machining of complex-shaped parts that are difficult to be completed by ordinary machine tools or cannot be machined at all.

What is CNC Machining?

CNC machining refers to the automatic control of machining tools and 3D printers by computers. A CNC machine processes a raw material (metal, wood, plastic, ceramic, composite, etc.) without human intervention according to a written program.

CNC is a material reduction manufacturing process that typically uses computer control and machine tools to turn billets into custom-designed parts. The process is suitable for a variety of materials, including metals, plastics, wood, glass, foam and composites, and is used in a variety of industries, such as large CNC machining, telecommunications parts and prototypes machining, and aerospace parts machining, which requires stricter tolerances than in other industries.

Material reduction manufacturing process(such as CNC machining), is often contrasted with additive manufacturing processes (such as CNC machining) or molding processes(such as liquid injection molding). Material reduction manufacturing process removes layers of material from the workpiece to produce custom shapes and designs, while additive process assembles layers of material to produce the desired shapes and molding process deforms and displaces raw materials into the desired shapes. The nature of automation of CNC machining enables the production of high-precision parts in mass production, bringing up cost-effectiveness. Although CNC machining shows some advantages over other manufacturing processes, there are limits to the sophistication that part design can achieve and the cost-effectiveness of producing complex parts.

What are the safety precautions in the CNC machining process?

1. It is forbidden to touch the tool tip and iron filings with your hands. The iron filings must be cleaned with iron hooks or brushes.

2. It is forbidden to touch the rotating spindle, workpiece or other moving parts by hand or in any other way.

3. It is forbidden to measure and change the speed during the processing, let alone wipe the workpiece with cotton silk, nor clean the machine tool.

4. During the operation of the lathe, the operator shall not leave the post, and the machine tool should stop immediately when abnormal phenomena are found.

5. Check the bearing temperature frequently. If it is too high, you should find relevant personnel for inspection.

6. During the processing, it is not allowed to open the protective door of the machine tool.

Three Steps to Implementing CNC

1. CAD File Conversion

The formatted CAD design file is run through a program, usually computer-aided manufacturing (CAM) software, to extract part geometry and generate digital programming code that will control CNC machine tools to produce custom-designed parts. CNC machine tools use a variety of programming languages, including G code and M code. The most famous CNC programming language is geometric code, also called G code. It manipulates when, where, and how the machine tool moves. That is to say, it can decide when to startup or shutdown, how fast to move to a particular location, which path to take, etc.. Miscellaneous function code, referred to as M code, controls auxiliary functions of the machine, such as automatic removal and replacement of the cover at the beginning and end of production respectively. After the CNC program is generated, the operator loads it into the CNC machine tool.

2. Machine Setting

Before an operator runs a CNC program, they must prepare a CNC machine tool for operation. These preparations include attaching the workpiece directly to the machine, machine spindle, machine vise or similar workpiece holding device, and connecting the required tools (such as drills and butt mills) to the appropriate machine parts. Once the machine is fully set up, the operator can run the CNC program.

3. Machining Operation Performing

The CNC program acts as the instruction for the CNC machine tool. It submits machine commands indicating tool actions and movements to the machine's integrated computer, which operates and manipulates machine tools. The start-up program prompts the CNC machine to begin the CNC processing process, and the program guides the machine throughout as it performs the necessary machine operations to produce custom-designed parts or products. If a company invests in purchasing and maintaining its own CNC equipment, CNC machining can be done in-house or outsourced to a specialized CNC machining service provider.

CNC Machining Type We Provide?

CNC machining is a manufacturing process suitable for a variety of industries including motor vehicle manufacturing, aerospace product and parts manufacturing, construction and agriculture. A wide range of products such as automotive frames, surgical equipment, aircraft engines, gears can be made with CNC process. Milling and turning are two common mechanical CNC machining operations.Vvvv

CNC Milling

Milling is a process in which a rotating multi-point cutting tool is used to remove material from a workpiece. In CNC milling, the CNC machine tool usually feeds the workpiece into the cutting tool in he same direction as the tool rotation, whereas in manual milling, the machine feeds the workpiece in the opposite direction to the tool rotation. The operational capabilities of the milling process include end milling -- cutting out shallow, flat surfaces and base cavities in the workpiece -- and peripheral milling -- cutting out deep cavities,such as grooves and screw threads in the workpiece.

CNC Turning

Turning is a machining process that uses a single point cutting tool to remove material from a rotating workpiece. In CNC turning, machine tool feeds the cutting tool in a straight line along the surface of the rotating workpiece, removing material from the circumference until the desired diameter is reached to produce cylindrical parts with external and internal features, such as grooves, tapers, and screw threads. The operational capabilities of turning process include boring, end face,grooving, and thread cutting. When it comes to CNC milling machines and lathes, milling and its rotating tools are better suited for more complex parts. However, lathes with rotating parts and fixed cutting tools are best for making circular parts more quickly and accurately.

Available materials for CNC machining Production

Metal (such as aluminum, brass, stainless steel, alloy steel, etc.), plastic (such as PEEK, PTFE, nylon, etc.), wood, foam, composite materials.

The choice of the best material for CNC manufacturing applications depends largely on the specific manufacturing application and its specifications. Most materials can be processed as long as they can withstand the processing process, that is, they have sufficient hardness, tensile strength, shear strength, and chemical and temperature resistance.

The workpiece material and its physical properties are used to determine the optimal cutting speed, cutting feed rate and depth of cut. The cutting speed is measured in surface feet per minute and is the speed at which a machine tool can cut into or remove material from a workpiece. Feed rate (in inches per minute) measures the rate at which the workpiece is fed to the machine tool. Depth of cut is the depth at which the cutting tool cuts into the workpiece. Typically, the workpiece will first go through an initial phase where it is roughed into an approximate, custom-designed shape and size, and then proceed to the finish phase, where it undergoes slower feed rates and shallower cuts to achieve more accurate and precise cut depths.
