CNC machined car parts refer to automotive components manufactured using computer-controlled CNC machine tools through processes such as cutting, milling, drilling, and grinding of metal materials. These parts, characterized by high precision, high consistency, and complex machining capabilities, are crucial components in the modern automotive industry, particularly suitable for applications with stringent requirements for surface quality and performance. The main types of CNC machined car parts include engine system components such as crankshaft connecting rods, camshafts, and intake manifolds; chassis system components such as steering knuckles, brake caliper bodies, and control arms; and CNC components specific to new energy vehicles, such as battery pack frames and electronic control system housings. This broad range of components offers significant advantages for both traditional gasoline-powered and new energy vehicles.
To meet the diverse needs of various scenarios, including fuel-powered vehicles, new energy vehicles, and special vehicles, our company supports customization services in the production of CNC machined car parts. We also cater to the individual needs of different state-owned enterprises and distributors, offering a complete customization process from "drawing design - process optimization - sample making - mass production." The customization process is as follows:
Customized Structure and Dimensions:Based on drawings or physical samples, we customize complex structures. Whether it's irregular curved surfaces, multi-hole layouts, precision threads, or other special designs, we can produce samples based on drawings, adjust the dimensions of parts to accommodate different lengths and mounting holes, and process integrated composite structural parts, replacing traditional multi-part assembly solutions.
CNC machined car parts are crucial components of automobiles, directly impacting a vehicle's power, safety, reliability, and durability. Therefore, our company places great emphasis on high precision, high mechanical performance, and environmental adaptability during production, adhering to stringent automotive industry standards. Key performance characteristics are as follows:
Precision Standards:
Dimensional tolerances for different parts are controlled within ±0.005mm~±0.01mm to ensure assembly requirements are met. Coaxiality of rotating parts is ≤0.003mm/m to prevent vibration and wear during high-speed rotation. Flatness of sealing surfaces is ≤0.005mm to ensure sealing performance and prevent brake fluid leakage.
Mechanical Performance:
For powertrain components, tensile strength ≥800MPa and yield strength ≥600MPa effectively prevent breakage and deformation under high-speed operation. For load-bearing components, bending strength ≥700MPa. For friction-moving parts, surface hardness must reach HRC58~62 to ensure no significant wear after 100,000 kilometers, while also considering corrosion resistance.
Environmental Adaptability:
CNC machined car parts need to be usable under complex conditions such as high temperature, low temperature, humidity, and vibration. Engine peripheral parts need to withstand a temperature range of -40℃ to 150℃ and will not deform or age even after long-term high-temperature use. They need to withstand vibrations with a frequency of 10~2000Hz and an acceleration of 5g for 100 hours without loosening or breaking.
