Why SAMSHION for Robotics
From CAD to Moving Robot in Days
Robotics development moves fast. We keep up — delivering first metal parts in 48 hours and scaling to production volumes without changing suppliers.
Bearing Fit Accuracy
H7 bore tolerances held consistently on aluminum and steel. Roundness to 0.005mm TIR. We verify every bearing bore on CMM before release — because a loose bearing fit destroys positional accuracy.
Speed: 48h to Metal Parts
CNC prototype parts in 48–72 hours for fast-moving robotics programs. SLA/SLS 3D printed parts available in 24 hours for form/fit checks before committing to metal. Fast DFM feedback same-day.
Lightweight Design Expertise
Aluminum 6061/7075 with pocketing, ribs, and topology-aligned stock removal. We read your FEA results and machine to your weight budget. Typical joint arm: 0.3–0.8kg aluminum machined to stiffness spec.
Type III Hard Anodize
Rotating and sliding joint surfaces anodized to HV 400+ hardness for wear resistance. Hard anodize on joint bores prevents fretting at high cycle counts. We account for the 12µm growth in your tolerance stack.
GD&T Joint Verification
True position of mounting bolt patterns, runout on joint pivot bores, and parallelism of flange faces verified on Zeiss CMM. Every joint assembly-critical feature documented on inspection report.
Full Iteration Support
Upload a new revision — we turn around DFM feedback in hours and new parts in days. We maintain version history and can re-run previous revisions. Robotics iteration cycles supported through the full development sprint.

Robotics Manufacturing FAQ
Can you hold H7 bearing fits on aluminum?
Yes. We routinely hold H7 bore tolerances on aluminum 6061 and 7075. For a Ø25mm bore, H7 = +0/+21µm. These are verified on CMM as standard. For tighter fits (H6), we apply final reaming with calibrated reamer sets.
Does hard anodize affect my bearing fit tolerance?
Yes. Type III hard anodize adds approximately 12–25µm per surface (grows inward into the bore). For H7 bearing bores, we machine the bore to a predetermined pre-anodize dimension and verify the final bore post-anodize with CMM. Call this out in your drawing notes.
How fast can I get first prototype arm links?
Standard CNC aluminum arm links: 3–5 days. Rush: 48–72 hours from order confirmation. SLA 3D printed form models for layout check: 24 hours. We recommend a 3D print form check before investing in metal if the design is still evolving.
Can you help with weight optimization?
Yes. If you share your FEA results or weight budget, our engineers can suggest pocketing patterns, rib structures, and material choices to hit your target weight while preserving stiffness and fatigue life. This is included in our free DFM review.
Do you supply carbon fiber composite parts?
We can supply pre-preg carbon fiber tubes and plates, but complex shaped CFRP parts are machined from plate stock by a partner facility. Contact us with your geometry — we coordinate the full supply chain for mixed material robotics frames.
Can you manufacture harmonic drive adapters?
Yes. Harmonic drive output flanges and wave generator adapters require tight concentricity (TIR ≤0.01mm) and precise bolt pattern positioning. We routinely produce these on 5-axis CNC with CMM verification. Specify the harmonic drive model for reference dimensions.
Do you offer sub-assembly for robot joints?
Yes. We offer mechanical sub-assembly including bearing press-fit, shaft-to-hub assembly, and hardware insertion. Assembled joints are verified for smooth rotation and freedom from binding before shipping.
What finish do you recommend for robot arm exteriors?
Bead blast + Type II anodize in black is the standard for robot arm exteriors. It provides a uniform premium appearance, good corrosion resistance, and a hard surface. Hard coat (Type III) anodize in black is used on joint surfaces subject to sliding contact.
