5. Carry out processing inspection and trimming.

The CNC machining process flow covers the design and formulation of machining processes, writing machining programs, machine tool clamping and tool clamping, machining operations, machining inspection and trimming. Each link requires accurate operation and strict control to ensure the efficiency of the machining process and the quality of the machining parts.

The biggest difference between CNC milling and turning is the movement of the cutting tool and the workpiece. In CNC turning, the workpiece rotates at a set speed while the cutting tool remains relatively stationary; CNC milling is to fix the workpiece in one position, while the cutting tool rotates around the workpiece to subtract excess material. CNC milling and CNC turning are still widely used CNC machining operations. Although these two machinings have similarities in CNC, their operating processes and machining purposes are very different; therefore, choosing the right processing technology is the key to the success of the project.

5-axis CNC machining is a multi-axis subtractive manufacturing process that involves the movement of the tool in five directions or shafts (X, Y, Z, A and B), and the five axes move in concert, allowing the machine tool to perform high-precision machining of five different faces of the workpiece in one clamp without repositioning the workpiece between operations. This multi-axis linkage capability makes it possible to process complex geometric shapes, especially suitable for parts with high requirements for spatial structure and free surfaces.

The number of CNC axes is the number of directions in which the CNC machine can move to produce the required parts. Taking the traditional three-axis CNC machine tool as an example, it naturally has a three-axis number. A three-axis machine tool can move laterally on the X axis, up and down on the Y axis, and forward and backward on the Z axis.

In addition to three linear axes, the 5-axis CNC machine also adds two axes, commonly known as A-axis and B-axis. These two additional axes enable the 5-axis machine to tilt and rotate the cutting equipment or parts to produce more complex geometry than the 3-axis machine.

5-axis machines become the secret to producing high-precision components without seams or welding marks;

5 Axle machining capabilities have transformed manufacturing industries such as automotive, healthcare, aerospace and agriculture.

After the CNC is processed, it generally needs to be surface-treated to enhance certain features of the parts, such as functionality, corrosion resistance, or brightly colored appearance;

Common surface treatment processes for CNC machining parts:

Anodizing

Electroplating Normal plating Galvanized Tin plating Copper plating Nickel plating Chrome blue/black Phosphate Passivation

Sandblasting

Powder spraying

polishing

Silk printing

Laser marking

Brushed

Paint, etc.

We usually define surface treatment requirements based on different material properties.
