Heavy Duty Custom Large Auto Parts CNC Machining
Precision Tolerance for Auto Parts Safety
The batch machining tolerance is stably controlled within ±0.02mm with a CPK value of ≥1.33, fully meeting the strict assembly precision requirements of automotive chassis and transmission systems.Full-time environmental control in the constant-temperature workshop eliminates thermal deformation of common automotive materials like aluminum alloy and alloy steel caused by temperature differences, keeping the tolerance fluctuation of 1000-piece batch production no more than ±0.01mm.
Full-process CMM inspection coverage, with a complete geometric tolerance inspection report attached to each batch of large automotive parts, eliminates the risk of vehicle installation failure caused by machining precision deviation.
Multi-Material Custom Machining for Auto Parts
It covers all common automotive materials including aluminum, steel, stainless steel, titanium alloy and engineering plastics, no external outsourcing is required, and all machining processes are completed in one stop.Custom exclusive tool path parameters are developed for high-hardness structural steel for auto parts, achieving a machined surface roughness of Ra0.8, which meets the wear resistance requirements of automotive transmission gears and differential housings.
Automatic stress relief pretreatment for auto parts is completed before machining. The finished parts have no hidden deformation after long-term vehicle operation, and the service life is extended by 30% compared with the industry conventional level.

Core Machining Capabilities
Full-Material Compatibility
No secondary outsourcing is required. All common automotive material machining processes can be completed in-house, covering 6061/6063 series aluminum alloys for new energy lightweight structural parts, high-strength structural steel and alloy steel for heavy-load chassis parts, stainless steel for automotive exhaust and fluid systems, titanium alloy for lightweight parts of high-performance racing cars and special vehicles, and high-strength engineering plastics for automotive interiors and electrical insulation components.
Strict Tolerance Control
All processes are carried out in a constant-temperature workshop to eliminate thermal deformation caused by temperature differences. The CPK value of batch machining reaches 1.33 or higher, and the tolerance fluctuation of 1000-piece batch production is controlled within ±0.01mm. Every finished product undergoes full-dimensional CMM inspection, and each batch is accompanied by a complete geometric tolerance inspection report, which can avoid the risk of vehicle installation failure caused by precision deviation. The machined surface roughness can reach Ra0.8, meeting the wear resistance requirements of transmission gears and differential housings.
