What are the process steps of CNC precision machining

CNC precision machining generally refers to the strict machining of computer numerical control control. Let's inquire about the process steps of CNC precision machining?

First, the placement requirements of the CNC precision machining process are considered according to the layout and vacancy of the parts and the requirements for positioning and clamping. The link is that the rigidity of the part will not be destroyed.

1. The processing of the first process can not affect the positioning and clamping of the next process, and the processing of ordinary tight parts in the middle should also be considered.

2. It is recommended to have excellent in-line processing procedures, and then carry out formal processing procedures.

3. Through similar positioning and clamping methods or similar tool processing procedures, Reduce the number of repeated positioning and tool changes, and the number of times the platen is moved, which can effectively avoid deviations and improve processing efficiency.

4. The multiple processes in the installation should first place the process with less damage to the rigidity of the parts.

Second, the technique of intensive sorting of tools, strictly follow the machining requirements of the parts, separate the required tools for the process, use the same tool to process all the parts that can be achieved, and then use the second and third tools to achieve The remaining aspects that can be realized can effectively reduce the tool change time, compress the empty travel time, and reduce unnecessary positioning deviation;

Third, according to the processing parts. For products with more processing content, CNC precision machining can be divided into several aspects according to their layout characteristics, such as inner shape, form, curved surface or plane. Generally, the plane and positioning surface are processed first, and then the hole is processed. First, a simple geometric pattern is given, and then a complex geometric pattern is processed. The parts with low positioning are excellently positioned, and then the parts with high positioning requirements are processed.

The manufacture marketing game of custom metal parts is changing with each innovation, and businesses of all products need to be ready to pounce.
Dongguan Yifeng Metal Co., Ltd. plans to produce and execute four marketing seminars, one per quarter, to help business owners see success by sharing important growth strategies and hosting interactive workshops.
Dongguan Yifeng Metal Co., Ltd. integrates research streams on team diversity and knowledge boundaries, and present a framework that considers the kinds of specific knowledge boundaries that must be spanned to achieve high-level, cross-boundary teaming.
