Frequently Asked Questions
Common questions about working with RapidAPlus.
The cost typically ranges from $35 to $120 per hour depending on machine complexity. 3-axis machines are the most affordable, while 5-axis and Swiss turning centers command higher rates. At RapidaPlus, we leverage Zhongshan’s lower overhead to offer high-precision machining at a fraction of Western labor costs.
China's advantage lies in a massive supply chain ecosystem and efficient labor. Factories in regions like Zhongshan have instant access to raw materials and specialized post-processing (anodizing, PVD) within a 5-mile radius, significantly reducing logistics time and total production costs.
Aluminum 6061 is the most popular due to its excellent machinability and strength-to-weight ratio. For high-strength applications, Titanium Grade 5 is preferred. If you need electrical insulation or chemical resistance, PEEK and Delrin (POM) are the top engineering plastic choices.
CNC milling uses a rotating tool to cut a stationary workpiece (best for prismatic/square parts). CNC turning rotates the workpiece against a stationary tool (best for cylindrical parts like shafts). Our Mill-Turn centers combine both, allowing complex cylindrical parts to be completed in one setup.
The industry standard is ISO 2768-m (typically ±0.1mm). However, precision engineering shops like RapidaPlus can achieve tight tolerances of ±0.01mm (10 microns) or even ±0.005mm for high-precision aerospace and medical applications.
For standard geometries, lead times are typically 3 to 5 business days. Complex parts requiring multi-axis setups or specialized finishing (like Hard Anodizing or PVD) may take 7 to 10 days. We also offer "Emergency Rush" services for 24-hour turnaround.
It depends on your goal. 3D printing is better for extremely complex "organic" internal geometries. CNC machining is far superior for material strength, surface finish (Ra roughness), and dimensional accuracy. For functional prototypes, CNC is usually the preferred engineering choice.
The "As-Machined" finish is typically Ra 3.2 μm. We can perform secondary operations to reach Ra 1.6, 0.8, or even 0.4 μm (mirror polish). We also offer bead blasting for a matte finish and anodizing for corrosion resistance and color.
Yes. RapidaPlus has a No Minimum Order Quantity (MOQ) policy. We support engineers through the "high-mix, low-volume" phase, helping you perfect a single design before moving to small-batch production.
You need a 3D CAD file (STEP, IGES, or X_T) for the geometry. Additionally, a 2D technical drawing (PDF) is required to specify tolerances, threaded holes, and critical surface finishes that aren't captured in the 3D model.
