Precision CNC Machined EOAT Components
RobotPartsCNC manufactures custom End-of-Arm Tooling components for robotics integrators, automation engineers, and product developers. From one-piece prototypes to production batches, we turn CAD designs into reliable functional hardware.
±0.01 mm
Standard tolerance
3–7 days
Prototype lead time
50–5,000+
Production quantities
Built for automation integration
Tool plates, vacuum modules, brackets, connection blocks, and custom mechanical interfaces for demanding robotic operations.
Custom EOAT manufacturing
Mechanical interfaces designed around your robot
Successful automation depends on an end effector that is rigid, repeatable, and compatible with the complete robotic system. We manufacture the precision components required for industrial, collaborative, and mobile robots.
Tool plates and interfaces
Tool changer adapters, robot-to-gripper mounting plates, keyed interfaces, and alignment features.
Grippers and mechanisms
Precision-machined fingers, jaws, linkages, bearing seats, shafts, and custom mechanical interfaces.
Vacuum modules
Manifolds, suction cup mounts, vacuum distribution blocks, and lightweight modules for dependable handling.
Brackets and housings
Sensor mounts, camera housings, rigid support frames, and structural brackets for complex workcells.
Alignment components
Dowel pin locators, precision bores, flat mounting surfaces, and repeatable keyed connections.
Multi-variant support
Efficient support for mixed part numbers, design iterations, pilot builds, and repeat production orders.
Precision machining capabilities
Repeatable fit for robotic assembly
RobotPartsCNC uses 3-, 4-, and 5-axis CNC milling and turning to produce the dimensional accuracy required for EOAT systems. Our equipment handles complex, thin-walled, and multi-sided geometries common to custom grippers and brackets.

Controlled surface roughness options
Tolerance and geometry +
Standard tolerances are maintained at ±0.01 mm, with tighter capability available for critical fits, bores, and alignment features.
Materials and finishes +
Aluminum, stainless steel, engineering plastics, carbon steel, and alloy steel can be matched with suitable finishing requirements.
Prototype through production +
Production support covers one-off prototypes, low-volume pilot builds, and repeat orders from 50 to 5,000+ units.
Material selection
Balance weight, strength, and wear resistance
Material choice is matched to payload, cycle life, environment, and contact conditions within your EOAT design.
Aluminum
6061-T6 and 7075-T6 for lightweight robot fingers and structural frames, with anodizing and hard-coat anodizing available.
Stainless steel
303, 304, 316, and 17-4PH for corrosion resistance, high rigidity, and food-grade or medical environments.
Engineering plastics
POM/Delrin, PEEK, and Nylon for non-marring gripper pads, insulators, and lightweight spacers.
Carbon and alloy steels
Selected for high-load mounting adapters, drive linkages, and other demanding structural applications.
Engineering support and DFM
Resolve manufacturability risks before production
Every CAD file is reviewed before machining begins. Our team identifies deep cavities, thin walls, difficult tool access, and other issues that could affect cost, part integrity, or lead time.
DFM review helps your team optimize for:
- ✓Faster prototype and production turnaround
- ✓Improved structural reliability and tool access
- ✓More predictable cost and repeatability
Quality control
Inspection built around assembly confidence
Robotic systems require precise assembly and repeatable interfaces. Our batch inspection process verifies critical dimensions and documents the materials and treatments used.
- Dimensional verificationCMM and optical measurement equipment.
- Fitment checksBearing fits, shafts, threads, and mating features.
- GD&T complianceTrue position, flatness, parallelism, and concentricity.
- Traceable documentsInspection reports, material certificates, and surface treatment certifications.
Prototype to production
One manufacturing partner across your project lifecycle
Rapid prototyping
Initial testing and design validation in 3–7 working days.
Low-volume manufacturing
Flexible pilot production for system integration and field testing.
Volume production
Optimized processes for consistent repeat orders and cost efficiency.
Global project support
Coordinated production from Shenzhen
Our supply chain supports secondary processes such as heat treatment, plating, and laser marking in-house or through qualified partners. We manage delivery through DHL, FedEx, UPS, and air or sea freight.
