CNC Machining

CNC Machining In CNC machining, the machining processes are often concentrated, and it is very important to locate them on the same basis. Therefore, it is often necessary to set some auxiliary datum or add some process bosses on the blank.
It is better to adopt a uniform geometric type or size for the shape and inner cavity of the part so that the number of tool changes can be reduced, and it is also possible to apply a control program or a special program to shorten the length of the program. The shape of the parts is as symmetrical as possible, which is convenient for programming with the mirror machining function of the CNC machine tool to save programming time.
CNC machining can be used to manufacture workpieces that are put into production on a regular basis. Market demand for some products is cyclical and seasonal. If a specific line is used, the gain is not worth the loss. The processing efficiency of standard equipment is too low, the quality is unstable, and the quantity is difficult to guarantee. After cutting the first batch (batch), the program and related product information can be retained in the CNC machining center. The next time the product is replicated, production can start with little lead time. The working time of the CNC machining center includes the preparation work time and the processing work time.CNC machining centers evenly distribute hours-long single-piece long machining to each workpiece, thereby reducing the average actual working time per production and greatly shortening the production cycle.
CNC machining can be used to produce high-precision workpieces. Some workpieces are not in great demand, but they are essential components that require high precision and short manufacturing cycles. Traditional technology requires multiple machine tools to coordinate work, resulting in long cycle times and low efficiency.
CNC machining can be used to produce batches of workpieces. The flexibility of CNC machining production is reflected in the rapid response to special requirements, which can quickly realize mass production to improve market competitiveness. CNC machining centers are suitable for small and medium batch production, and the minimum batch production when using CNC machining centers.
CNC machining can be used to produce composite-shaped workpieces. The application of four-axis linkage and five-axis linkage CNC machining machines and the maturity and development of CAD/CAM technology has greatly increased the complexity of machining workpieces. The use of DNC makes the processing content of the same program sufficient to meet various processing needs, thus making the automatic processing of complex workpieces easily.
What are the types of CNC machining?
1. CNC drilling is a machining process that uses multi-point drilling to create cylindrical holes in a workpiece. In CNC drilling, the CNC machine typically feeds a rotary drill perpendicular to the surface of the workpiece, resulting in a vertically aligned hole with a diameter equal to the diameter of the drill in the drilling operation.
2. CNC milling is a machining process that uses a rotating multipoint cutting tool to remove material from a workpiece. In CNC milling services, CNC machines usually feed the workpiece into the cutting tool in the same direction as the cutting tool rotates. In contrast, in manual milling, the machine provides the workpiece with the opposite rotation to the cutting tool.
3. CNC turning is a machining process that uses a single-point cutting tool to remove material from a rotating workpiece. In CNC turning, a CNC machine (usually a lathe or lathe) feeds a cutting tool in a linear motion along a rotating workpiece surface. Removing material around the circumference until the desired diameter is achieved will produce a CNC-turned part with internal and external cylinders such as grooves, tapers, and threads. The operational capabilities of the turning process include leveling, facing, grooving, and thread cutting.
The advantages of the CNC machining process.
1. CNC machining usually has tool holders and tool magazines that can automatically change tools. The tool change process is automatically executed under program control. Therefore, operations are relatively concentrated. Process concentration brings huge economic benefits:
1. Reduce machine tool footprint and save shop floor.
2. Reduce or not use any intermediate links (such as intermediate inspection of semi-finished products, temporary storage, processing, etc.), thus saving time and human resources.
3. Automation, no manual tool control is required in the CNC machining process, and the degree of automation is high. The benefits are obvious.
4. During machining, CNC workers are excluded from machining most of the time, which is very labor-saving.
5. Machining automation of CNC machining eliminates worker fatigue, carelessness, estimation, and other human errors on common machine tools and improves product consistency.
6. Automatic tool change for CNC machined prototypes makes the machining process compact and increases labor productivity.
7. Although conventional general-purpose machine tools are flexible, they are inefficient. Instead, certain conventional machines are efficient. However, it has low adaptability to parts, high rigidity, and insufficient flexibility, and it is difficult to adapt to the fierce competition in the market economy.
Packing and Shipping.
1. Each product is carefully packed with bubble bags and packed in cartons. In order to cause scratches due to knocks, which will affect the quality and use of the product, we will use wooden boxes specially designed for export for packaging and transportation.
2. All products will be transported according to customer needs, such as express, air shipping, sea shipping, and railway shipping.
