CNC Machined Covers FAQ
What cover types can you manufacture?
We manufacture custom CNC machined covers including equipment covers (machine enclosures), motor covers (motor housings and protection), pump covers (fluid containment), gearbox covers (gear protection), inspection covers (removable access panels), sealed covers (watertight enclosures), ventilated covers (cooling and airflow), and custom profile covers. All covers are CNC machined and finished to your exact specifications.
What materials are best for lightweight covers?
Aluminium 6061-T6 is the standard choice for lightweight covers — excellent machinability, good strength-to-weight ratio, and natural corrosion resistance. Aluminium 7075-T6 offers higher strength for large span covers. Stainless steel 304 is ideal when corrosion resistance is critical. Titanium is used for extreme-lightweight aerospace covers. All materials are easily machined to complex profiles with minimal waste.
What tolerances can you hold on cover dimensions?
Standard CNC machining on covers achieves ±0.05mm on all dimensions. Precision machining with CMM verification can hold ±0.01mm. Flatness and straightness are typically within ±0.1mm per 100mm — tighter control available with surface grinding. For covers requiring precise mounting interfaces or sealing surfaces, we recommend CMM verification.
What is the typical lead time for custom covers?
Quote turnaround is 2 business days. Once order is confirmed, lead times depend on cover complexity and current shop load. Simple covers typically deliver in 3–5 business days. Complex multi-feature covers may require 5–10 business days. Surface finishing and coatings add 2–5 business days. Rush lead times are available — contact our engineering team for expedited scheduling.
Can you manufacture covers with sealing features?
Yes. We routinely machine covers with sealing surfaces including gasket grooves, O-ring grooves, labyrinth seals, and integrated seal pockets. Sealing-surface flatness and parallelism are critical — we recommend CMM verification for all pressure or fluid-containing covers.
Do you offer venting or cooling features for covers?
Yes. Ventilation and cooling features are standard on our covers. Options include louvered vents (directional airflow), perforated panels (distributed cooling), ribbed interior surfaces (heat dissipation), and integrated fan mounting. All venting is integrated into the CNC machining — no secondary assembly required.
