Scojet 3 to 5-Axis CNC Milling Service

From 3-axis basics to intricate 5-axis projects, our precision CNC milling makes your designs come alive with unmatched accuracy and craftsmanship.


Types of CNC Mills


The most widely used type of CNC milling machine. The full use of the X, Y, and Z directions makes a 3 Axis CNC mill useful for a wide variety of work.


This type of router allows the machine to rotate on a vertical axis, moving the workpiece to introduce more continuous machining.


These machines have three traditional axes as well as two additional rotary axes. A 5-axis CNC router is, therefore, able to machine 5 sides of a workpiece at in one machine without having to remove the workpiece and reset. The workpiece rotates, and the spindle head is able to also move around the piece. These are larger and more expensive.

CNC Milling Tolerances & Standards

DescriptionGeneral Tolerance or Standard
Maximum Part SizeMilled parts up to 80” x 48” x 24” (2,032 x 1,219 x 610 mm).
Distance DimensionsFor features of size (Length, width, height, diameter) and location (position, concentricity, symmetry) +/- 0.005”.
Orientation and Form Dimensions0-12″ +/- 0.005″, Angularity 1/2 degree. For 24″ and beyond please consult Xometry’s Manufacturing Standards.
Precision TolerancesWe can manufacture and inspect to tight tolerances per your drawing specifications including GD&T callouts.
Minimum Feature Size0.020” (0.50 mm). This may vary depending on part geometry and chosen material.
Threads and Tapped HolesWe can accommodate any standard thread size. We can also machine custom threads; these will require a manual quote review.
Surface FinishThe standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified when getting a quote.
Edge ConditionSharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print.

Custom CNC Milling Finishes

Surface Finish on Milled Parts

Typically, we break (debur) the edges on all machined parts. All machined plastic parts are left as-machined, which may leave visible tool marks. Some metal parts, on the other hand, allow more choice. Parts left with sharp edges should be handled with care.
