Custom CNC Machined Aluminum Housing for Industrial Robotic Arm Assembly

Quick detail

This robotic arm structural housing is integrally machined from solid aluminum billet. It features irregular contour, multi-cavity inner grooves and distributed bolt holes with strict positional tolerance. Sandblasted surface treatment improves corrosion resistance and visual uniformity. Full dimensional inspection is implemented for every workpiece to guarantee assembly accuracy.

Product description

The aluminum housing serves as a core mounting component of robotic joint assembly. Complex outer profile and multiple deep pockets require multi-side CNC milling to form in one process. The array of precision bolt holes on the circular flange demands tight positional tolerance to ensure seamless fit with rotating modules. Our machining team reviews drawings for DFM risks before production. Flatness, perpendicularity and hole position are verified by precision measuring instruments. We can adjust surface finish and thread specification to match different robotic system assembly requirements.

FAQ

Q1: Can you customize the hole layout on the circular flange?

A1: Yes. Hole diameter, quantity and pitch circle can be fully customized based on your assembly drawings.

Q2: Is 5-axis machining required for this irregular housing?

A2: Complex side profiles and deep inner cavities adopt 5-axis milling to reduce multiple re-clamping errors.

Q3: Can you support prototype sampling with short lead time?

A3: Prototype service is available. Send 3D files to get lead time and quotation.

Q4: What is the maximum workpiece size you can process?

A4: Max machining length up to 1000mm. Submit drawings for manufacturability assessment.

Q5: Will CMM inspection reports be provided upon request?

A5: Yes, CMM inspection reports can be supplied for critical dimensions for each batch.
