12-hour quote response for clear drawings. Practical lead time review for prototype,
small-batch, and multi-process robot part projects.
Robotics Parts That Fit OUJI Well
We are a good fit for drawing-based robotic components where machining accuracy,
assembly fit, surface treatment, and fast engineering feedback matter more than
catalog-style standard parts.
Good Fit
- Prototype robot parts before design freeze
- EOAT, gripper fingers, adapter plates, and tool plates
- Small-batch robot brackets, covers, housings, and plates
- Motor mounts, sensor brackets, rail plates, and fixture blocks
- Mixed CNC machining, sheet metal, finishing, and inspection projects
Not the Best Fit
- Mass-produced standard robot catalog components
- Off-the-shelf motors, reducers, sensors, and controllers
- Projects without drawings, dimensions, or clear requirements
- Ultra-high-volume commodity parts where price is the only factor
- Complete robot system design, wiring, programming, or integration services
Custom Parts for Robot Structures, EOAT, Motion Systems and Fixtures
Robotics projects often require many small custom parts instead of one single
large component. OUJI helps customers manufacture machined parts used in robot
structures, automation tooling, grippers, mounting systems, and inspection fixtures.
Robot Structure Parts
Aluminum frames, arm links, base plates, lightweight brackets, covers, housings, and support plates.
EOAT & Gripper Parts
Gripper fingers, tool plates, adapter blocks, vacuum fixture plates, custom jaws, and locating blocks.
Motion & Mounting Parts
Motor mounts, bearing supports, linear rail plates, sensor brackets, camera mounts, and alignment parts.
Automation Fixtures
Inspection jigs, positioning fixtures, assembly plates, test blocks, and small-batch production tooling.
Manufacturing Support for Prototype and Low-Volume Robot Parts
From one-off development parts to low-volume production batches, OUJI combines
machining, secondary processes, and supplier coordination to support practical
robotics part manufacturing.
CNC Milling
For aluminum plates, brackets, housings, mounting blocks, fixture plates, and complex robot structure parts.
CNC Turning
For shafts, spacers, bushings, rollers, pins, collars, and round parts used in robotic assemblies.
5-Axis Machining
For compact parts with multi-side features, angled surfaces, tight access areas, and complex mounting geometry.
Sheet Metal Support
For covers, guards, electrical box panels, lightweight brackets, robot cell covers, and protective structures.
Surface Finishing
Anodizing, plating, passivation, black oxide, bead blasting, brushing, and other finishes for robot parts.
Inspection Support
Dimensional inspection, key feature checks, thread checks, surface review, and report support when required.
Materials for Lightweight, Wear-Resistant and Assembly-Critical Robot Parts
Robotic components often need a balance of weight, rigidity, wear resistance,
corrosion protection, and assembly stability. We review material and finishing
requirements based on part function, mounting area, and tolerance risk.
| Material Group | Typical Robotics Use |
|---|---|
| Aluminum 6061 / 7075 | Frames, brackets, EOAT plates, lightweight mounting blocks, robot structure parts. |
| Stainless Steel 303 / 304 / 316 | Shafts, pins, corrosion-resistant brackets, clean environment parts, small precision parts. |
| Steel / Tool Steel | Wear blocks, tooling parts, fixture bases, heavy-duty supports, hardened contact parts. |
| POM / PEEK / PTFE / Nylon | Low-friction blocks, insulating parts, soft contact areas, lightweight gripper pads. |
| Anodizing / Plating / Passivation | Color coding, corrosion protection, wear resistance, appearance, and functional surfaces. |
For moving and mounted robot parts, we pay special attention to fit surfaces,
coating thickness, sliding contact areas, threaded holes, and assembly-critical dimensions.
Common Review Points
- Is the part weight-sensitive?
- Will the surface be anodized, plated, or passivated?
- Are there bearing, rail, or motor mounting faces?
- Do threaded holes need protection after finishing?
- Are there burr-sensitive cable, sensor, or sliding areas?
Inspection for Moving, Mounted and Assembly-Critical Robot Parts
Robot parts are often small, but their assembly risk can be high. A small hole
position error, burr, flatness issue, or coating change may affect motor mounting,
rail alignment, sensor positioning, or gripper repeatability.
Mounting Accuracy
Hole position, counterbores, threads, datum surfaces, motor and bearing mounting areas.
Motion Stability
Flatness, parallelism, guide rail support areas, sliding surfaces, and rotating contact features.
Assembly Fit
Interface dimensions, mating faces, inserts, dowel holes, alignment features, and stack-up risks.
Surface & Edge Control
Burr removal, anodizing or plating risk review, edge protection, and packaging for finished parts.
From Robot Part Drawings to Practical Manufacturing Review
Send your 2D drawings, 3D files, material requirements, finish requirements,
quantity, and target application. We review manufacturability, process route,
finishing risks, and inspection focus before quoting.
