CNC machining - Haide Mingcheng Intelligence Science and Technology (Shenzhen) Co.,Ltd.

3-Axis CNC Milling:

4-3-axis machining is processed by linear feed axes X, Y, and Z; machining features: The cutting tool direction remains unchanged during movement along the entire cutting path.

4-Axis CNC Milling:

The two rotating shafts first fix the cutting tool in an inclined position, and then process it by the feed shafts X, Y, and Z. This kind of machine tool is also called a positioning five-axis machine tool.

5-Axis CNC Milling:

5-axis machining linear interpolation motion from feed axis X, Y, Z and any five axes of rotation axes A, B, C of X, Y, Z

CNC turning:

Mainly used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces with arbitrary conical angles, complex rotating inner and outer curved surfaces, cylinders, conical threads, etc., and can perform grooving, drilling, reaming, reaming and boring, etc.

The working principle of CNC machining can be divided into three basic processes: program preparation, program transmission and execution, and machine tool control.

Programming: It is the starting point of the entire CNC processing. Engineers use CAD/CAM (computer-aided design/computer-aided manufacturing) software to compile corresponding CNC programs based on the size, materials, processing methods of the processing objects. The program will describe the parameters such as each cutting action, tool selection, and feed speed in detail to ensure processing accuracy and process requirements;

Program transmission and execution: The written program is transmitted to the CNC machine tool through the control system and started execution. The CNC system will control the movement of each axis of the machine tool according to the instructions in the program, including the linear motion of the three-dimensional coordinate axes of X, Y, and Z and the rotational motion of the rotation axis;

Machine tool control: The machine tool performs machining tasks according to the compiled program instructions. The relative movement between the tool and the workpiece determines the machining effect. By controlling the feed speed, spindle speed and cutting path of the machine tool, complex machining tasks are completed;

The CNC system can also monitor various parameters in real time during the processing process, and adjust the machine tool movement according to the processing conditions to ensure machining accuracy.

The quotation for CNC (computer CNC) processing is usually determined by multiple factors, including material cost, processing time, equipment depreciation, labor costs, post-processing processes, etc. The following are the detailed calculation methods and influencing factors of the CNC processing quotation: The cost of material includes the expenses of raw materials (such as aluminum, steel, copper, etc.), calculated by the weight or volume of parts. Example: The price of aluminum is about US$6 per kilogram, and a part weighs 0.5 kilograms, and the cost of material is US$3. Processing time The time cost of CNC processing is the core, including: Programming time: According to the complexity of the parts, it is usually calculated in hours, surface treatment costs, inspection costs, packaging costs, factory management costs, logistics costs, etc. The above are the expenses incurred in the CNC process of the entire part.

CNC machining parts are not available in minimum order quantity or minimum order quantity, which means we can efficiently manufacture prototype parts and even single-use custom parts at relatively low cost, which is possible for other manufacturing methods. For example: For plastic parts, it is necessary to first make a metal mold, which is an expensive process; therefore, we are not cost-effective in making some custom parts. Given that there is no minimum MOQ for machining parts, CNC machining technology is suitable for factories and enterprises with different quantity requirements, customized designs and prototypes.

In the workflow of a CNC (Computer CNC) processing plant, every link is crucial. From order acceptance, programming to processing and quality inspection, each step requires a high degree of precision and coordination to ensure that the final product meets customer requirements. Our order process:

1. Customer demand and order confirmation

2. Process Analysis and Programming

3. Material preparation and equipment settings

4.CNC processing and monitoring

5. Quality inspection after processing

6. Packaging and delivery

7. Summary and Improvement

In short, the workflow of the CNC processing plant is a closely connected, precise and efficient process. Each link needs to be carefully arranged and executed to ensure that the final product meets customer requirements and meets the best quality standards.

The time of CNC processing is affected by factors such as the complexity of processing, process coordination, equipment quantity, and work efficiency. The company has 300 CNC processing equipment, advanced management mechanism, high efficiency, and delivery time is about 3 to 10 days;

In addition, the delivery time of CNC processing is also affected by the complexity of parts. The complexity of the workpiece is high, which requires more effort to be spent during programming. During the processing process, the probability of failure will increase a lot, and the entire delivery time will be delayed;

Finally, the more surface treatment process some CNC parts require, the more time it takes. For example, some aluminum alloy workpieces need to be oxidized; some stainless steel workpieces need to be passivated, which takes a certain amount of time. Compared with those workpieces that only require natural polishing, the delivery time will be relatively long.
