Enclosure Machining

Notes for Designers

__________

To aid machining, reduce processing time and thus cost, consider these factors in custom and bespoke enclosure design:

• Specify the largest internal corner radii as possible

• Keep wall cross sections thicker and more stable

• Keep tolerances as open as possible

• Where not critical, specify rougher internal surface machined finishes

• Minimise the number of faces with features that require machining to reduce set-up time

• Deep enclosures increase cutting tool length, reducing tool stability and slows processing time. Consider moving away from an “enclosure and lid” design to have a split line 50% down the depth of the enclosure, changing to a top and bottom half style assembly.

If you're still weighing your options and want to see how CNC machining compares to other manufacturing methods for enclosures, see our article 'Which manufacturing method is best for enclosures?'

When your design is proven, we can help with final manufacturing machining and finish design so the specification is clear and can be manufactured repeatedly to the correct quality specification.
