Summary of CNC machining center experience, essential for efficient machine operation

CNC machining, also known as CNC lathe machining. The VL-850 CNC machining center, commonly known as a column type CNC machining center, is a common CNC lathe machining equipment in the drilling industry. CNC lathe machining is computer-controlled production and processing after programming. Therefore, CNC machining has the advantages of stable production and processing quality, high machining accuracy, repeated high precision, and can produce and process simple surfaces with high efficiency. In the specific production process, human factors and practical operational work experience pose a significant threat to the final production and processing quality.

Allocation of CNC machining center sequence

Generally speaking, the allocation of production and processing sequence should be based on the structure of the parts and the condition of the rough embryo, as well as the need for precise positioning and clamping. The top priority is to ensure that the stiffness of the steel parts is not damaged. The order should generally be carried out according to the following standards:

1. The CNC production and processing of the previous process must not jeopardize the precise positioning and clamping of the next process. If there is a universal production and processing process flow intersecting in the middle, it should also be comprehensively considered.

2. First, carry out the process of adding inner walls, and then proceed with the production and processing process of exterior design.

3. It is best to connect the production process of CNC with the same precise positioning, clamping method, or the same knife to reduce the frequency of repeated precise positioning, tool replacement, and pin movement.

4. For multiple processes carried out in the same installation, the process flow with minimal damage to the stiffness of the steel parts should be allocated first.

What aspects should be noted when clarifying the method of clamping steel parts?

When clarifying the precise positioning standards and clamping plan, the following three points should be noted:

1. Ensure the standardization of design schemes, processing techniques, and programming calculations.

2. Try to avoid clamping frequency as much as possible and ensure that all the surface layers to be produced and processed can be CNC produced and processed after one precise positioning.

3. Prevent the use of manual service adjustment plans that occupy machines.

4. The fixture should be open smoothly, and its precise positioning and clamping mechanism should not harm the feed in CNC production and processing (such as causing impact). When encountering such situations, the method of using pliers or adding bottom plate screws for clamping can be selected.

The production and processing process, as well as the clamping and precise positioning standards of steel parts, may seem like the first step in high-efficiency manufacturing, but strict control at the root is considered essential.
