Robotics leaves no room for error.
A robot that fails one tenth fails the whole system.
And that’s where CNC machining comes in.
At MSJ Technology, we have been manufacturing parts for demanding industries for more than 40 years. Robotics is one of them: precision, lightness and reliability are not optional.
In this article we explain what this sector really needs and how we work to meet it.
What does robotics require from CNC machining?
The answer is clear: accuracy, repeatability and stability.
But let’s go into detail.
1. Extreme precision
A robot repeats movements thousands of times.
If a part is not within tolerance, the error is multiplied.
We are not talking about millimeters here. We are talking about microns.
2. Light but rigid parts
Less weight = more speed + less consumption.
But without losing rigidity.
The balance between weight and strength is key.
3. Perfect finishes
- Burr-free
- No vibration
- No backlash
Because any imperfection affects the movement.
4. Suitable materials
Not all materials are suitable.
You have to choose according to:
- effort
- environment
- friction
- weight
5. Complex geometries
Many robotics parts are not simple.
They require simultaneous 5-axis machining to achieve:
- accuracy
- fewer errors
- better finish
What parts do we machine for robotics?
At MSJ Technology we work with robotics, automation and advanced machinery manufacturers.
Real examples of parts we manufacture:
- Structural supports
- Housings and technical covers
- Precision shafts and bushings
- Components for grippers and actuators
- Special tooling and tools
- Components for vision systems
- Parts for collaborative robots (cobots)
- Guiding and transmission elements
Each robot is different, but they all have one thing in common: they need parts that fit together the first time.
What materials are used in robotics?
The choice of material defines the performance of the part.
Aluminum 6082 / 7075
- Slight
- Rigid
- Easy to machine
Ideal for structures and robotic arms.
304 / 316 stainless steel
- Resistant
- Stable
- Perfect for demanding environments
Widely used in the food or chemical industry.
Technical plastics (POM, PA, PEEK)
- Low friction
- Insulators
- Very light
Perfect for moving or contact parts.
Alloy steels
- High mechanical strength
- Durability
For parts subjected to load or wear.
Why is 5-axis machining key in robotics?
Because it simplifies the whole process and improves the result.
Clear advantages:
- Complex geometries in a single operation
- Fewer fastenings → less error
- Better surface finish
- Increased accuracy
- Reduction of production times
In robotics, this translates into fewer failures and higher throughput.
