Fabrication Tolerances for Dimensional Variance in Sheet Metal and Machined Parts
CNC Machining Tolerances
We specify a standard dimensional tolerance of ± 0.005" for CNC machined parts. However, it is possible to achieve a tighter tolerances on our routers, lathes, 3-axis mills and 5-axis mills. If you require a tighter tolerance, please contact us, as tighter tolerances may increase the cost of your project and have to be clearly defined upon ordering.
Using a thinner sheet metal in CNC machining may require CNC jigs to be used - this may add a cost to your design build. Talk to your account manager about your options - they will confer with our engineering and design services team about your options.
