CNC turning is a process where a computer controls the rotation of a workpiece on a lathe, and the tool shapes it into a cylindrical part. The workpiece is fixed on a rotating spindle, and as it rotates, the tool moves along its length according to the program design. This process can include threading, slotting, and drilling, while maintaining high precision and a smooth surface. CNC turning technology holds a significant position in modern manufacturing, and is applicable to the processing of complex parts in industries ranging from aviation to automobiles.
• Designing the workpiece: Use CAD software to design and model the workpiece.
• Writing the processing program: Based on the workpiece design, write the processing program, including tool paths, cutting parameters, etc.
•Installing the workpiece: Install the workpiece on the CNC machine and perform initial coordinate settings and workpiece clamping.
•Processing the workpiece: Load the converted machine tool instructions into the numerical control system and control the machine to perform the corresponding cutting operations through the numerical control system.
CNC turning is widely used in the manufacturing of parts such as shafts, pins, rods, flanges, bushings, pulleys. It is widely applied in industries such as automobiles, aerospace, electronics, pipelines and industrial machinery.

SJ-MFG offers a wide range of surface treatment options, which are applied to the surface treatment of 5 axis CNC parts. The main purpose is to meet specific functional requirements, enhance the appearance color, and improve the chemical and corrosion resistance of the part surface.
A protective oxide layer is formed on the surface of metal products, which is corrosion-resistant, wear-resistant, has a variety of colors and a beautiful appearance. It is most commonly used for aluminum alloy materials.
Using the impact effect of high-speed sand flow to clean and roughen the surface of the parts, a certain degree of cleanliness and different roughness can be achieved, and is applicable to both metal and plastic materials.
Heated in a high-concentration chemical solution, it forms a dense protective film, which is used to enhance the corrosion resistance, improve the appearance and minimize light reflection. It is commonly used for steel and stainless steel materials.
Enable the powder paint to adhere to the parts, forming a hard coating film on the surface. The coating thickness is uniform and it is wear-resistant. It is commonly used for metal parts.
Liquid paint is sprayed onto the surface of the parts by compressed air. It is widely used for surface coating of products such as automobiles and electronics, and is applicable to both metal and plastic materials.
Coating a layer of another metal on the surface of the metal part, such as nickel, chrome, gold, zinc plating etc, it is corrosion-resistant, wear-resistant and has a beautiful appearance. It is suitable for metal parts.
Based on the surface treatment with chemical plating solution, the parts are immersed in the plating solution to form a metal film, no need for electricity. Suitable for metals and a few plastic materials (ABS, PP, PC).
Using the charged particles in the solution to form a uniform coating on the surface of the parts. Suitable for metal parts.
Reduce the surface roughness of the parts and achieve a shiny, smooth and mirror-like surface effect. Applicable to metal parts and plastic parts.
By grinding the surface of the parts to create lines, a fine and lustrous effect is achieved. Applicable to metal parts.
Using high-energy-density lasers to irradiate specific areas of the parts, special marks are left. Applicable to metal and plastic parts
Press the screen-printed plates with graphics and text onto the surface of the parts, and offer a wide range of color options. Suitable for metal and plastic parts.
SJ-MFG’s standard tolerances of CNC turning are applicable to ISO 2768 (medium) for plastic machining and ISO 2768 (fine) for metal machining.
