WHAT SETS US APART

CNC capabilities

CNC Milling

We offer both 3 and 5-axis machining capabilities. To optimize for speed of production, we recommend minimizing the number of setups to leverage 3-axis machining.

We accept the following minimum and maximum part sizes.

Z
Min.
2.5mm [0.1”]
2.5mm [0.1”]
1.0mm [0.04”]
Max.

Compound surfaces

Compound surfaces (also known as organic or spline surfaces) are no problem with Fictiv, so long as other minimums are met.

CNC machining service internal radius
Internal Radius

We support features with internal radii down to 0.4mm (0.016").

CNC machining service hole diamter
Hole Diameter

We can drill holes as small as 0.5mm (0.020") in diameter.

CNC machining service hole depth
Hole Depth

Our maximum drillable hole depth is 12x the drill bit diameter.

CNC machining service feature depth
Feature Depth

We recommend a maximum depth of cut of 5x tool diameter in both metals and plastics. Chat with us if your project requires more.

CNC Turning

We offer both standard and live-tooling CNC turning. As with CNC milling, we recommend limiting the need of live-tooling to speed up the prototyping process. 

We accept the following minimum and maximum part sizes.

Milky-white finish, and is slightly translucent.

COLORS

Natural

Min Wall thickness

Hardness

Rockwell B35

tensile strength

15,000 psi

FINISH AND APPEARANCE
