Why Robotics Companies Prefer Aluminum 6061 for CNC Machining

In the robotics and automation industry, weight and precision matter.

Over the past few years, many customers searching for:

• custom CNC machining service for robotics

• precision aluminum robotic arm bracket

• low volume CNC machining for automation components

have shifted to Aluminum 6061 CNC machining.

Why?

Because 6061 offers:

• Excellent machinability

• Good strength-to-weight ratio

• Stable anodizing surface

• Cost-effective raw material pricing

• Tight tolerance capability (±0.01mm achievable)

As a CNC machining supplier in Shenzhen, we’ve manufactured robotic arm brackets, motor housings, and structural supports for European and US automation companies.

Real Case: Optimizing Machining Strategy for a Robotic Arm Bracket

A client contacted us through Google after searching:

rapid CNC machining China aluminum robotics parts

They needed:

• 300 pcs custom aluminum robotic arm brackets

• Tolerance ±0.02mm

• Black anodizing

• 18 days delivery

Initial Challenge

The original drawing was designed with:

• 6 deep pocket areas

• unnecessary sharp internal corners

• thick wall structure increasing weight

This would increase machining time by 22%.

Our Optimization Proposal

Before production, we always confirm drawings in detail.
(We never cut metal blindly.)

We suggested:

1. Adjusting pocket depth to reduce tool extension

2. Increasing internal corner radius to fit standard tooling

3. Reducing wall thickness from 12mm to 9mm

Result?

• Machining time reduced by 14%

• Tool wear reduced

• Final unit cost lowered by 18%

• Weight reduced by 11%

For robotics companies, weight reduction directly improves motion response speed.

it's about controlling risk at every stage.

Why Google Clients Choose GT-PROTO

Many customers find us using keywords like:

• CNC machining parts factory

• CNC machining supplier Shenzhen

• upload drawing for quotation

• low volume CNC machining for robotics

What makes long-term cooperation possible?

✔ Engineering communication
✔ Process optimization suggestion
✔ Realistic lead time
✔ Stable quality control

If You Are Designing Robotics Components…

Before you finalize your drawing, ask:

• Is the corner radius suitable for standard tool?

• Can wall thickness be reduced?

• Does tolerance match function, or overdesign?

• Is material grade optimized?

Small design improvement = big cost saving.
