Project Description
Precision Automotive Parts CNC Machining
CNC machining is widely used for many sectors in the automotive industry. These precision cnc machined parts have tight-tolerance dimension and execllent surface finish, and more suitable for assemblies and aesthetic appearance. Also meeting some specific functional requirements exactly. The below sectors are common applied.
- Engine components: These excellent airtight components need high precision dimension and high strength so that ensure the great power of vehicles and automibles. such as cylinder heads, engine blocks, and crankshafts. These parts require high precision to ensure optimal performance.
- Head Lighting Housings: Various head lighting design requires considering of Modern systems combine optics, electronics, and thermal management. So these head lighting housings require the best work performance. The cnc machining can just create high performance products.
- Transmission components: CNC machining is used to create transmission components such as gears, shafts, and housings. In order to ensure these parts coincidental assemly and excellent running, they require high precision to ensure smooth operation and durability.
- Braking system components: Like brake calipers, rotors, and drums, they must be assemblied reasonably, and have smooth running once unexpected situation happened. These parts require high accuracy and precision to ensure safety and good braking performance. CNC machining can ensure their precision and performances.
- Interior and exterior components: Automotive interior and exterior components such as door handles, dashboards, and trim pieces. Flexible geometries, exquisite appearance and superior surface finish require high precison cnc machining and more luxurious coating treatments.
Overall, CNC machining play a critical role in the production of automotive components, helping to ensure that vehicles are safe, reliable, and perform optimally. As a trusted CNC machining service China partner, JingXing, The cnc machining shop China ensures end-to-end precision and high performance from prototyping to mass production.

We are well-handled of precision process in different plastics and metal materials. Also involve of various finishes for these cnc machined parts, include of painting, powder-coated, anodized, electroplating and PVD coating etc.
15+ Years’ Experience:
JINGXIN focuses on custom Non-standard CNC and regular precision cnc machined parts such as fittings, valves, hydraulic components, electric motor shafts, transmission and pump parts, sprocket wheels, wear parts for packing machines and electronic and medical surgical tools. As one leading cnc machining server, we have insisted on being satisfied of customer requirements and completed and accumlated 1000 regular customers, especially, our trueworth customer, branded automotive manfacturer, volvo, who have worked with us for 10 years.
Advanced Cnc machining Equipment
provide various material cnc machined parts using world-class CNC machines, including CNC turning and milling centers. This allows us to deliver high-quality, on-demand precision machined components, with typical tolerances ranging from ±0.002mm to ±0.01mm for metal parts. Please visit our whole factory show for more details about our precision CNC milling equipment.

optimizing consistently the tooling path and confirm the best CNC turn process solution according to the design and customer’s requirements. Accept various metals and special engineering plastics. Common stainless steel, copper, aluminum, zinc alloy and alloy steel cnc machining, like medium to small sized precision parts, such as locknut shafts, electric motor shafts, precision-turned aluminum components for electronic and medicinal products.

For some precision automotive parts, which require more complex tooling path, cnc milling is most common. Using multi-axis model tooling path, mill zero flatness and some any arch surface. Control accurately the step deepth on the workpiece with computer digital control programming. The tolerance range is from 0.05um-0.1um.
High Precision Inspection Instrument

the workpiece has three axes to be measured, including point, line, plane, circle, oval, cylinder, cone, ball, arc, and keyway etc., once the workpiece has been measured its simple of the geometric element decomposition that is to distinguish how many geometric elements of workpiece composition, so that it can be quickly complete the measurement.

moves stage XY to get the coordinates after the measurement point by means of the amount of movement measurement. The light emitted by light source is projected onto the project screen through the work piece to be measured, which can be dimensioned. Dimensional measurement usually can include straightness, parallelism, verticality, symmetry, flatness, roundness, concentricity, coaxiality, and other geometric tolerance settings.
Rapid Prototying Services
JingXing’ Rapid CNC machined prototyping services means that it can provide fast, high-precision production of functional prototypes directly from 3D CAD data, helping shorten product development cycles—especially in automotive and communication electrics.
- CAD file (STEP/IGES) submission
- CNC programming (CAM) and toolpath generation
- Multi-axis machining (3-axis, 4-axis, or 5-axis)
- Post-processing (deburring, anodizing, polishing, coating)
- Inspection (CMM for tight tolerances)
In short, rapid CNC machining services deliver speed, precision, and flexibility, making them essential for modern product development and engineering validation.
Fast Delivery Goods
Fast delivery on time & Rush services

Cnc machining process is rapid manufacturing process, compare to some cast parts and plastic injection parts are created by the die and mold. its operation is the tool cutting the block and shape superior surface finish and tight tolerance dimension precision parts through repetitive and fatigue actions. So the delivery time can be shortened as soon as possible.
1. Simple operation for real machining steps, Minimzing the delivery time ,
2. On-time delivery by worldwide express: UPS, DHL, FedEx, TNT, etc.
3. Proper safe packing: Exported standard carton and wooden case steam.
