CNC precision machining is CNC machining

CNC precision machining is CNC machining. After the design drawings are written into the program, the computer is connected to the CNC machine tool, and the operation of the CNC machine tool is controlled by programming to complete the machining of precision workpieces. CNC precision machining is mainly suitable for small batches , Various types of workpiece processing, precision machining.

Not all materials can be precision machined. For example, if some materials with high hardness exceed the hardness of the machined parts, some special materials are not suitable for precision machining.

1. Requirements for material hardness. For some occasions, the higher the material hardness, the better, but it is limited to the hardness requirements of the machined parts. The material to be machined cannot be too hard. cannot be processed.

Second, the material should be moderately soft and hard, at least one grade lower than the hardness of the machine parts. At the same time, it also depends on the function of the processing device, and the material selection for the machine parts is reasonable.

Advantages:

1. The number of tooling is greatly reduced, and complex tooling is not required for machining parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.

2. The processing quality is stable, the processing precision is high, and the repeatability is high, which can meet the processing requirements of aircraft.

3. The production efficiency is higher in the case of multi-variety and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of a better cutting amount.

4. It can process complex surfaces that are difficult to process by conventional methods, and even process some unobservable processing parts.

In the CNC precision machining industry, the machining accuracy largely determines the quality of the machined parts, and the machining of CNC precision parts itself is a highly demanding machining method , compared with traditional processing methods, it can achieve better results, so what are the advantages of CNC precision parts processing?

Multi-axis control linkage

Usually, three-axis linkage is used more. Some adjustments can be made to four-axis, five-axis, seven-axis or even more linkage axis machining centers.

Machine paralleling

The functions of the common CNC precision machining center are also relatively fixed, and the machining center and turning center, or vertical and horizontal machining centers can be combined together. It can increase the processing range and processing capacity of the machining center.

Tool damage warning

Using some technical detection methods, it is possible to detect the wear and damage of the tool in time and give an alarm, so that the tool can be replaced in time to ensure the processing quality of the parts .

Tool life management

It can manage multiple tools working at the same time and multiple blades on the same tool to improve production efficiency.

Machine overload and power-off protection

Set the maximum load level according to the load in the production process. When the load reaches the set value, the machine tool can realize automatic power-off and shutdown, and the machine tool will be activated. to protection.
