principle
Advancing technology and societal development drive increasing demands for the performance and quality of precision-machined products. Product performance and quality depend on design and are ensured by precision hardware processing, manufacturing, and assembly quality, encompassing both processing accuracy and surface quality. The surface quality of precision mechanical parts is a critical indicator, especially for reliability under high-speed, high-temperature, and high-pressure conditions.
Precision machining transforms a blank's size, shape, and performance to meet design requirements. However, surfaces produced by turning precision mechanical parts, such as cylindrical surfaces, are not ideal. Machining creates a very thin surface layer on the part with characteristics significantly different from the internal matrix. During precision metal processing, the surface undergoes elastic and plastic deformation under complex stresses involving wedging, extrusion, fracture, and friction throughout the cutting process. The combined action of cutting force, cutting heat, and surrounding media alters the workpiece surface's original geometric characteristics and physical-mechanical properties. Therefore, "surface quality" evaluates the conformity of the machined part's surface layer, considering geometric, physical, chemical, or other engineering properties, to the part's technical requirements. Its main content is:
Surface roughness: Micro-geometric features of small-spaced peaks and valleys on the precision metal-processed surface, primarily formed by the cutting tool's motion trajectory during precision machining, typically with a wave height-to-wavelength ratio greater than 1:50.
Importance
Custom CNC machining enables manufacturers to create unique components for specific applications, from prototypes to optimized end-use products. Key benefits include:
Precision and Accuracy: Computer-controlled programming and high-speed tools achieve tolerances as tight as ±0.001mm, ensuring parts meet exact dimensions critical for precision-dependent industries.
Complex Geometries: Capable of producing intricate shapes and multi-sided designs unachievable manually, multi-axis mills and Swiss lathes create parts with internal channels, complex threads, and contoured surfaces.
Material Versatility: CNC machines work effectively with diverse materials including aluminum, stainless steel, titanium, brass, and high-performance plastics, suiting varied industry needs.
Scalability: Services adapt from rapid prototyping to small or large batch production, with quick setups and automated tool changes minimizing downtime.
Cost Efficiency: While initial setup costs exist, CNC machining becomes cost-effective long-term through reduced labor, faster production, minimal waste, and the elimination of multiple tools/processes.

FAQ
- Q: I want to keep our design a secret. Can we sign an NDA?
- A: Sure, we can sign an NDA before you send the drawing.
- Q: What’s your MOQ?
- A: We have no MOQ for our new customers; we are accepting small orders to support your trial order, new design, and marketing development.
- Q: How does Crida compare to other suppliers on price?
- A: As compared to Chinese suppliers, we choose not to compete on price but to offer the highest levels of quality, rapid response, and professional results. And that’s why so many customers cooperate with us, compared with the price, they need a reliable partner to avoid serious losses caused by annoying after-sales or even the trouble of finding someone.
- Q: How do you ship the goods and how long does it take to arrive?
- A: We usually ship by DHL, UPS, FedEx or TNT. It usually takes 3-5 days to arrive. Airline and sea shipping are also optional.
- Q: How many inspections should be carried out for a project?
- A: Generally, products will undergo the following four inspections: incoming inspection, first production inspection, sampling inspection and pre-shipment inspection. Among them, sampling inspection will be conducted many times.
