FAQs

What are the advantages of five-axis CNC machining over three-axis? Do you offer five-axis machining services?
The main advantages of five-axis machining are: 1. It allows for the machining of complex polyhedrons in a single setup, improving precision and efficiency; 2. It enables machining areas that three-axis machining cannot reach (such as deep cavities and curved surfaces at unusual angles); and 3. It reduces the need for fixtures. We offer five-axis CNC milling services, specializing in precision parts for aerospace, medical devices, and complex molds.
Can complex parts be machined?
Yes, CNC multi-axis machining excels at processing complex geometries and precision parts.
Can you do proofing or small batch processing?
We are very welcome to provide you with quick response.
How to ensure tool life and machining accuracy when machining carbide or hardened steel (hardness above HRC50)?
Machining high-hardness materials requires specialized strategies: using high-performance carbide or CBN/PCD tools; optimizing cutting parameters (low speed, high feed, and shallow depth of cut); ensuring equipment rigidity and stability; and employing high-pressure coolant for efficient chip removal. Our extensive experience in machining high-hardness materials and specialized equipment ensure effective tool wear control, ensuring machining accuracy and surface quality.
How to ensure quality stability and consistency for large-volume machining orders?
We ensure consistent quality during mass production through the following measures: 1. Comprehensive first-article inspection and confirmation; 2. Standardized processing procedures and process cards; 3. Regular spot checks (dimensional and appearance) during production; 4. Automated testing equipment; and 5. A comprehensive equipment maintenance system to ensure machine tool accuracy. SPC process control can be implemented upon request.
Can you provide one-stop machining services including post-processing (such as heat treatment and surface finishing)?
Yes, we offer a one-stop solution from raw material to finished product. In addition to core machining processes (turning, milling, wire EDM, etc.), we also assist in arranging or directly provide supporting services, including heat treatment (quenching, tempering, carburizing, etc.), grinding (surface grinding, cylindrical grinding), and various surface treatments (sandblasting, polishing, oxidation, electroplating, spraying, etc.), streamlining your supply chain management.
