ILLUSTRATIVE APPLICATION COMPONENTSWEKO manufactures CNC-machined aluminum and stainless-steel structural components for robotics and automation. We review interfaces, datums, material, finish and inspection requirements against your released drawing before confirming capability.

WHAT THE APPLICATION DEMANDS
Control the features that control performance.
Each project is reviewed against its own geometry and risk. These are common engineering priorities—not universal tolerance claims.
Low-mass structure
Wall thickness, rib geometry and machining access are balanced against stiffness and distortion risk.
Repeatable batches
Revision control, fixtures and inspection scope are aligned before repeat production begins.
DESIGN FOR MANUFACTURING
A useful quote identifies risk—not only price.
For robotics & automation components, the manufacturability review connects the 3D model to the drawing: datum structure, critical fits, wall sections, tool access, material condition, finishing and the measurement method.
- Confirm the released revision and units
- Separate functional requirements from cosmetic zones
- Identify assembly-critical bores, faces and threads
- Agree inspection evidence before production
COMMON COMPONENTS
Structural parts made from your controlled design.
WEKO supplies machined metal components only. Electronics, bearings, complete assemblies and product design remain with the customer or approved system supplier.

Five stages, one controlled requirement.
Each stage answers a different manufacturing question before more time and material are committed.
RFQ & drawing review
Align revision, material, quantity, critical features and commercial requirements.
Prototype
Test manufacturability and functional interfaces using production-relevant material.
Engineering validation
Review fit, assembly, finish and inspection evidence; capture approved changes.
Production validation
Confirm fixtures, machining sequence, process checks and packaging on a controlled batch.
Repeat production
Run the released revision with agreed controls, documentation and change discipline.

MATERIAL & PROCESS MATCH
Choose the grade around exposure, fit and finish.
Final alloy, condition, certification and finish remain controlled by the released drawing and agreed quotation.
General-purpose structural aluminum
Aluminum 6061
A practical machinable alloy for motor housings, end covers, brackets and equipment structures where low mass, corrosion resistance and stable production matter.
Open material guide
Higher-strength lightweight aluminum
Aluminum 7075
A higher-strength aluminum option for weight-sensitive robot, drone, reducer and motion-system interfaces when the released design requires more mechanical performance than a general-purpose alloy.
Open material guide
General corrosion-resistant stainless steel
Stainless Steel 304
A widely used stainless grade for shafts, sleeves, end caps, clean structural interfaces and equipment hardware where general corrosion resistance and a durable metallic finish are useful.
Open material guide
Higher-corrosion-resistance stainless steel
Stainless Steel 316
A stainless grade often considered for demanding corrosion, cleaning or outdoor exposure around motion equipment, subject to the actual medium, temperature, geometry and released specification.

ENGINEERING FAQ
Answers before you send the drawing.
What robotics parts can WEKO machine?+
WEKO focuses on metal structural components such as robot joint housings, actuator housings, motor covers, shafts, sleeves and mounting brackets. Finished robots, motors, bearings, electronics and complete product design are outside our supply scope.
Can you support a robotics prototype before production?+
Yes. We can review prototype, low-volume and repeat-production requirements. The machining and inspection plan is matched to the released drawing, quantity and application risk.
Which files should be included in a robotics RFQ?+
Send a STEP or STP model, a dimensioned PDF drawing, quantity, material and finish requirements, plus critical fits, GD&T and inspection-reporting expectations.
Do you guarantee a universal CNC tolerance?+
No. Achievable tolerance depends on geometry, material, feature size, setup and inspection method. WEKO confirms capability against the actual drawing before quotation.
