CNC machining center has become one of the indispensable equipment in industrial production. It can accurately control cutting, drilling, grinding and other processing processes through precise control of CNC programs, greatly improving production efficiency and product quality. However, in the production process of CNC machining centers, process and fixture design are two very important issues. This blog will introduce the specific content of these two issues.

technological design
Process design is one of the most critical links in the production process of CNC machining centers. A good process design can improve production efficiency and product quality, while an unreasonable process design will cause a lot of secondary processing and even product scrapping. In process design, the following factors should be considered in formulating an excellent production process:

1. Material properties.

For different materials, we need to formulate corresponding process plans to achieve the ideal processing effect. For example, when machining titanium alloys, high-pressure cooling and appropriate cutting parameters are required.

2. Tool selection.

Different cutting tools have different performances, and the correct choice needs to be made according to the materials being processed. The material, structure, size and service life of the tool should all be taken into consideration.

3. Processing sequence.

In multi-step processing, it is necessary to reasonably plan the sequence of processes in order to improve processing efficiency. For example, when manufacturing a whole cushion, milling is performed first, and then drilling, 3D printing, etc. are performed.

Fixture design
Fixture design is also an important part of the production process of CNC machining centers. The fixture is a device that holds the raw material on the machining center. A good fixture design can improve the fixing effect of the fixture, reduce errors in the processing process, and improve processing accuracy.

For fixture design, the following aspects should be considered:

1. Fixture positioning.

The fixture must be positioned according to the shape of the part and processing requirements to ensure that the part cannot move or be deformed due to processing force.

2. Clamp pressing force.

The clamping force of the fixture should match the processing force to avoid bending or deforming the parts.

3. Clamp material.

The clamp material needs to meet requirements such as high strength, good stability, and light weight. For example, when clamping complex work blocks, high-strength locks and pneumatic clamps can be used.

In short, process and fixture design are very important steps in the production process of CNC machining centers. Correct process design and fixture design can improve processing efficiency and product quality, and reduce production costs. On this basis, scientifically and rationally plan the processing plan to comprehensively improve production efficiency.
