Product Introduction
Our small parts CNC machining service focuses on providing high-precision micro components for industries such as aerospace, medical, electronics and precision instruments. With advanced CNC machining technology, we are able to produce small parts CNC machining products with sizes as small as millimeters, ensuring excellent accuracy and consistency. Whether it is complex geometry or high tolerance requirements, our small parts CNC machining service can meet customers' high standards for micro parts.
Main Features
High-precision machining: tolerances can reach ±0.002 mm, suitable for high-precision requirements of tiny parts.
Diverse materials: support metals (such as aluminum, stainless steel, titanium) and engineering plastics (such as PEEK, POM) to meet different application scenarios.
Complex geometry: capable of processing tiny holes, fine grooves and complex 3D structures.
Surface treatment: polishing, anodizing, electroplating and other treatments are provided to improve the performance and aesthetics of parts.
Manufacturing process and technical challenges
In CNC machining of small parts, tiny sizes and complex features bring significant technical challenges. For example, we once processed a batch of micro stainless steel parts with a diameter of only 0.3 mm for medical equipment customers. The parts contain multiple micro holes with a depth of 0.1 mm and a tolerance requirement of ±0.002 mm. The difficulty lies in the process of machining tiny parts. Tool selection, vibration control and thermal management must be precisely coordinated to avoid part deformation or surface defects.
Technical difficulties:
Micro parts are prone to dimensional deviation or surface roughness due to tool vibration or heat accumulation during high-speed machining.
Solution
Micro tool optimization: Use ultra-fine carbide tools with a diameter of 0.1 mm, combined with a high-precision spindle (speed up to 50,000 RPM) to ensure stability.
Vibration suppression: Minimize vibration during machining through customized high-rigidity fixtures and dynamic balancing technology.
Precision Cooling: Using Minimum Quantity Lubrication (MQL) technology, we precisely control the amount of coolant to avoid the impact of liquid on tiny parts.
Through these measures, we have successfully achieved a tolerance of ±0.002 mm and a surface roughness of Ra 0.4 microns, meeting the stringent requirements of the medical industry for high-precision CNC machined parts.
