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 the quality of precision hardware manufacturing, processing, and assembly, encompassing both machining accuracy and surface quality. The surface quality of precision mechanical parts is a critical indicator, particularly for part reliability under high-speed, high-temperature, and high-pressure conditions.

Machining transforms a blank's size, shape, and properties via precision processes to meet design specifications. However, surfaces like those produced by precision turning are not ideal. Processing forms a very thin surface layer on the part with characteristics significantly different from the internal substrate. During precision metal machining, the surface undergoes elastic and plastic deformation under the complex stress state of cutting, involving wedging, extrusion, fracture, and friction. Combined forces (cutting force, cutting heat, and surrounding media) alter the workpiece surface's original geometric characteristics and physical-mechanical properties. Consequently, '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. Key aspects include:

Surface Roughness: The micro-geometric features of small-spaced peaks and valleys on the precision metal-processed surface. This results primarily from the tool's motion trajectory during precision machining, with a typical wave height-to-wavelength ratio greater than 1:50.

Importance

Customization through CNC machining allows the production of tailored components for specific applications, whether prototypes or final products. Custom CNC turning and milling deliver significant advantages:

Precision and Accuracy: CNC machines, utilizing computer programming and high-speed cutting tools, maintain tight tolerances (±0.001mm), guaranteeing parts meet required dimensions, essential where precision is non-negotiable.

Complex Geometries: Intricate shapes and multi-sided designs, difficult or impossible to produce manually, are achievable; multi-axis CNC mills and Swiss lathes produce parts featuring internal channels, complex threads, and contoured surfaces.

Material Versatility: A wide material range—aluminum, stainless steel, titanium, brass, high-performance plastics—can be processed, making CNC ideal for diverse industry requirements.

Rapid Prototyping to Mass Production: Highly scalable, custom CNC services efficiently handle one-off prototypes through to large batches, aided by quick setups and automated tool changes reducing downtime.

Cost Efficiency: Despite initial setup costs, long-term cost-effectiveness results from lower labor, increased production speed, minimal material waste, and streamlined production by eliminating multiple tools and processes.

PACKING

PACKING PROCESS

The packing method uses EPE foam and Kraft paper.

Inner Layer: EPE foam protects the aluminium profiles from impact.

Outer Layer: Kraft paper protects the aluminium profiles from water and ensures package tightness.

FAQ

• Q: I want to keep our design a secret. Can we sign NDA?
• A: Sure, we can sign NDA before you send the drawing.

• Q: How does Crida ensure the quality of my parts?
• A: Once your order is confirmed, we will perform a full Design for Manufacturing (DFM) review to point out any issues that our engineers feel may affect the quality of your parts. Each batch of goods must have first article assurance(FAA), and then IPQC inspections for many times, Final inspection reports before shipment

• Q: Can Crida make design drawings for me?
• A: We do not provide design services. You are responsible for submitting 2D and 3D CAD drawings, and we can then provide a Design for Manufacturing review upon receiving your order.

• Q: After-sales service team
• A: If you have any problems after receiving the product, you can provide feedback through voice call, video conference, email, etc. within one month. Our team will provide you with solutions within a week.

• Q: What tolerances can Crida achieve?
• A: There is no given set of tolerances that fits all processes and materials. In every case, the final tolerances on your part will depend on a number of factors, including but not limited to: Part size Design Geometry The number, type, and size of features Material(s) Surface finish Manufacturing Process Once your order is confirmed, we will review your design and provide a design for manufacturing review, pointing out any areas where we may not be able to achieve your desired tolerances. It’s helpful if you can specify which areas in your design have critical tolerances that must be met and which can be slightly modified if needed to reduce the time and costs involved.
