Core Machining Services

  • 1 CNC Milling — 3-axis, 4-axis, and 5-axis milling for complex geometries.
  • 2 CNC Turning — Precision turning and live-tool machining for rotary parts.
  • 3 Mill-Turn — Combined turning and milling in a single setup.
  • 4 Precision Machining — Tight tolerances, precision bores, and bearing fits.

Surface roughness Ra 0.4–3.2 µm. Milling up to 1000 × 600 × 600 mm and turning up to Ø400 × 800 mm.

Machining Capabilities for Robotics and Automation

RobotPartsCNC supports parts requiring tight tolerances, precision bores, bearing fits, thin-wall machining, complex geometries, multiple setups, and controlled surface finishes. Whether you are developing a robotic joint, actuator housing, AMR platform, or custom gripper, our machining processes are built around the mechanical requirements that drive robotics performance.

M

CNC Milling

3-axis, 4-axis, and 5-axis milling for robot joint housings, actuator housings, robot arm components, base plates, and structural parts.

T

CNC Turning

Precision turning and live-tool machining for robot shafts, sleeves, output flanges, bearing seats, and other rotary components.

5

5-Axis CNC Machining

Complex geometries and multi-setup parts machined in fewer operations, improving accuracy and reducing lead time.

MT

Mill-Turn Machining

Combined turning and milling in a single setup for high-precision rotary and prismatic parts with tight concentricity requirements.

P

Precision Machining

Tolerances down to ±0.005 mm, controlled surface roughness, and inspection with CMM, micrometers, bore gauges, and thread gauges.

F

Surface Finishing

Anodizing, hard anodizing, bead blasting, electroless nickel plating, passivation, black oxide, powder coating, and laser marking.

From Prototype to Production

RobotPartsCNC supports customers throughout the product development cycle. Start with one-piece prototypes for proof-of-concept and functional testing, then scale into low-volume or production manufacturing with the same supplier — no costly supplier switching.

Why Robotics Teams Choose RobotPartsCNC

We specialize in components for robotics and automation rather than positioning ourselves as a general-purpose machine shop. Our engineering team reviews drawings and CAD models before manufacturing and provides DFM feedback on thin walls, deep cavities, difficult tool access, and excessively tight tolerances.

Robotics-Focused

Components for robots, cobots, AMRs, grippers, and automation systems.

Flexible Quantities

One-piece prototypes through repeat production orders of 10,000+ pieces.

DFM Support

Engineering review to improve manufacturability, reduce cost, and shorten lead time.

Quality Documentation

Inspection reports, CMM reports, and material certificates available on request.

Integrated Supply Chain

Anodizing, plating, heat treatment, grinding, and assembly coordinated together.

Global Shipping

DHL, FedEx, UPS, air freight, sea freight, and customer-designated forwarders.
