An Overview for :
What is CNC Machining processing

CNC machining is an advanced part processing method. It uses milling, turning and electric discharge (EDM) methods for subtractive processing. The CAD/3d product design is imported into the CNC program, and the G code will control the tool to cut on the metal & plastic materials. Accurately remove materials outside the design and create parts close to the final design.

The most advanced CNC machining center has complex CNC programs and more coordinate settings to provide the best stability and accuracy. Therefore, CNC machining is an ideal manufacturing method that can quickly create rapid prototypes and complex structures. Mass production.

We suggest that the design of thin-walled parts should meet the minimum thickness of 1mm or more, and the minimum thickness of plastic materials should be 1.5mm.
In the process of parts processing, the vibration of the equipment will affect the accuracy of the product fixation, will cause excessive processing or damage to the product, etc., and in the process of material processing, the cutting of the tool will increase the stress release inside the material, which will affect the accuracy ,

Reasonable wall thickness will help avoid the appearance of substandard products.

Many customers like to design complex geometric figures on products as corporate logos. We often recommend that customers design these texts so that the depth of the indentation does not exceed 0.5mm, which will greatly reduce the processing cost and avoid unnecessary wear of the embossment. .
At the same time, Mulan MFG can provide better engraving services such as screen printing, laser marking, and etching.

For many CNC lathe machining shaft products, in order to ensure the concentricity of the product during the machining process, a process hole with a depth of about 0.5mm-1mm is often processed at both ends of the material for positioning. Without affecting the use, We will not do the treatment. If it is unavoidable in the customer's design, then we will fill in the process hole by welding and polish it.

Threaded hole is a very common part setting. Regardless of American thread and metric thread, please pay attention to the design of the bottom of the threaded hole. It is necessary to reserve a processing space of 1.5mm-2mm. This is the size of the leading bevel angle of the processing tool.
For weak steel materials such as plastics and aluminum, it can be designed to use steel wire thread coils or metal thread inserts to extend the life of the product at the threaded parts.

Why choose CNC machining services?
