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.
