Reducing Lead Times for Custom Aluminium Control Panel Enclosures with 5-Axis CNC Machining
The Challenge
A manufacturer of industrial automation equipment approached Strategic Innovations Dundee Ltd after experiencing repeated delays from multiple suppliers. The company required a batch of custom aluminium control panel enclosures used to house electronic components inside factory machinery.
Although the part looked relatively simple from the outside, it required precise machining to ensure every connector, switch, mounting hole, and cable opening aligned perfectly during final assembly. Small inaccuracies could lead to time-consuming modifications or prevent the enclosure from fitting correctly.
Previously, the customer sourced machining, finishing, engraving, and assembly preparation from different companies. This increased transportation costs, extended production schedules, and created unnecessary project management challenges.
The client wanted a single subcontract engineering partner capable of manufacturing complete enclosures with consistent quality, shorter lead times, and dependable delivery for future production runs.
The Engineered Solution
After reviewing the technical drawings, the engineering team developed a streamlined manufacturing process using several in-house capabilities.
Each enclosure was produced from high-grade aluminium billets selected for their strength, corrosion resistance, and lightweight properties.
The external profile and internal pockets were machined using 5-axis CNC milling, allowing multiple sides of the enclosure to be completed in one setup. This reduced handling while improving machining accuracy.
Precision holes for connectors, switches, display panels, and mounting points were then machined to ensure every component would fit exactly as specified in the customer’s drawings.
Where smaller cylindrical spacers and threaded inserts were required, CNC precision turning produced accurate precision turned parts that were ready for assembly.
For several narrow internal slots that standard cutting tools could not easily reach, the engineering team used EDM wire erosion Scotland technology to create clean, accurate openings without affecting surrounding material.
After machining, every enclosure received:
- Edge deburring for improved safety.
- Fine surface finishing for a professional appearance.
- Laser marking with part numbers and identification labels.
- Final inspection before moving into sub-assembly engineering, where inserts, fasteners, and mounting hardware were installed.
Because every production stage was completed under one roof, the customer benefited from simplified communication and a faster manufacturing schedule.
This project demonstrated how CNC machining Scotland specialists can efficiently manufacture complete industrial components while reducing the need for multiple subcontractors.
The Outcome & Operational Impact
The improved production process delivered significant operational benefits.
- Production lead time was reduced by 34% compared with the customer’s previous supply chain.
- Single-setup 5-axis CNC milling reduced machining setup time by 42%.
- All connector openings and mounting features were produced accurately, eliminating manual rework during final equipment assembly.
- Combining machining, laser marking, and sub-assembly engineering into one project reduced supplier coordination and administrative costs.
- The customer now benefits from a repeatable manufacturing process that supports both prototype development and larger production batches.
