Professional Miniature Part Machining Technology

Reliable CNC Stainless Steel Metal Parts - OEM Customization Service
We are equipped with multiple precision CNC lathes and miniature machining centers, capable of machining various stainless steel parts with diameters ranging from 0.5-20mm. Through optimized micro-cutting parameters and specialized tooling systems, we ensure dimensional accuracy of parts up to ±0.005mm and surface roughness up to Ra0.4μm. Especially for parts and irregularly shaped structures, we employ special forming processes to ensure high precision and consistency even at minute dimensions.
Premium Stainless Steel Material Selection
We offer miniature parts machining services using a variety of stainless steel materials, including 304, 316, and 420. 304 stainless steel possesses excellent overall performance and corrosion resistance; 316 stainless steel performs even better in harsh environments; and 420 martensitic stainless steel can achieve higher strength and hardness through heat treatment. All materials undergo rigorous material testing to ensure suitability for micro-machining requirements.
Advanced Processes Guarantee Processing Quality
Made micro-sized stainless steel parts faces technical challenges such as difficult dimensional control, high surface quality requirements, and control of work hardening. We effectively solve these problems through innovative processes: using specialized micro-diameter cutting tools and optimizing cutting geometry parameters; employing micro-lubrication technology to ensure machining quality; and controlling material property changes through precision heat treatment processes. These process measures ensure that we can consistently produce high-quality micro-parts.
We have established a complete micro-parts inspection process, equipped with professional testing equipment such as high-magnification microscopes, image measuring instruments, and surface roughness testers. In addition to routine dimensional inspections, we also conduct material composition analysis, hardness testing, and corrosion resistance testing on the parts to ensure that product performance meets stringent requirements. We establish complete quality files for each batch of products, achieving full quality traceability.
Our stainless steel metal parts are widely used in various high-end fields such as precision instruments, electronic equipment, and optical systems. Leveraging our professional micromachining technology and extensive manufacturing experience, we are committed to providing every customer with the highest quality micro-parts, using precision manufacturing processes to ensure reliable performance for precision equipment.
