CNC Machining Capabilities at Xinjuli
CNC Milling
Experience CNC milling in action as rotating cutting tools shape a workpiece, ideal for crafting intricate geometries, grooves, slots, and contours.
CNC Turning
In CNC turning, the workpiece rotates as the cutting tool removes material, a process that typically produces cylindrical or symmetrical components.
5-Axis Machining
Highly complex and precise parts become possible with 5-axis machining technology. Creating these parts is often difficult or impossible using traditional 3-axis or even 4-axis machines.

Our Top Demanded CNC Machining Solution
We offer a range of CNC machining services tailored to your needs. From high-precision milling to laser cutting, we provide scalable, efficient, and high-quality manufacturing solutions for any industry.
CNC Milling
Experience CNC milling in action as rotating cutting tools shape a workpiece, ideal for crafting intricate geometries, grooves, slots, and contours.
CNC Turning
In CNC turning, the workpiece rotates as the cutting tool removes material, a process that typically produces cylindrical or symmetrical components.
5-Axis Machining
Highly complex and precise parts become possible with 5-axis machining technology. Creating these parts is often difficult or impossible using traditional 3-axis or even 4-axis machines.
CNC Drilling
We possess the ability to process a wide range of complex components, handling both small-batch prototyping and large-scale production. Utilizing a diverse range of drilling equipment—including vertical drilling machines, bench drills, and radial drills—we efficiently perform drilling operations up to 7 cm in diameter, achieving patterns that range from simple to intricate designs. This process is widely applicable to various materials, including metals and alloys (such as aluminum, steel, and copper) as well as polymers.
Friction Welding
When traditional welding faces challenges with dissimilar materials or high-strength requirements, our friction welding technology offers the ideal solution. It achieves metallurgical-grade bond strength, ensuring welds match the base material's strength. This method also boosts production efficiency and reduces energy consumption. The result is more reliable, cost-effective integrated components.
Laser Welding
Precision welding for micro and small components achieves deep penetration with minimal heat input. This approach minimizes the heat-affected zone. It also controls workpiece deformation while producing aesthetically pleasing, robust, high-quality welds.
Wire Cutting
This is a specialized machining technique that uses a continuously moving metal wire as the tool electrode. Examples include molybdenum or copper wire. High-frequency pulse voltage is applied between the workpiece and the electrode wire via a pulse power supply. Spark discharges are generated that instantly and locally melt or vaporize the metal. This process shapes the workpiece with precision and accuracy.

CNC Machining FAQs
Your design should be prepared in a 3D CAD format compatible with CNC machines. It's essential to consider machining constraints and optimize the design for manufacturing (DFM) to ensure efficient production and cost-effectiveness.
Lead times for CNC machining projects can vary based on the complexity of the part, the material used, and the volume of production. Typically, it can range from a few days for simple parts to a few weeks for complex, multi-process projects.
CNC Machining is ideal for producing precise, durable parts from a wide range of materials, especially metals. Compared to 3D printing, it is typically faster for hard materials and offers superior surface finishes. In contrast to injection molding, CNC is better suited for low-volume production and one-off prototypes, while injection molding excels in high-volume manufacturing of plastic parts.
Making design modifications after the CNC machining process has started can be complex and may incur additional costs and lead time. It's best to finalize the design before the process begins. However, if necessary, we can work with clients to make changes, understanding that it may affect the project timeline and cost.
Post-processing options for CNC machined parts include heat treatment for stress relief or hardening, surface finishing such as polishing, anodizing, or powder coating for aesthetic and protective purposes, and assembly services if the part requires integration with other components.
Xinjuli takes the confidentiality of client designs and intellectual property very seriously. We have strict non-disclosure agreements (NDAs) in place and follow industry best practices for data security and privacy protection.
