HOW IT IS MADE

How a milled part is made

An end mill clears the pocket in passes, a smaller one circles out the bores and a drill sinks the holes.

DRAWING RULES

Design rules

3 rules for CNC milling drawings

  1. Keep inside corner radii at least one third of the pocket depth.
  2. Avoid deep, narrow pockets: a depth of more than four times the width needs special tooling.
  3. Call out only the tolerances that matter. Everything else follows the general tolerance.

Questions2 questions about CNC milling and orders
What tolerances can you hold?

Our best is ±0.01 mm in CNC milling (many features, not only hole positions; measured hole positions are typically 0.02 mm). Where the drawing gives no tolerance, the general tolerance of the process applies. Each capability page lists it.

How fast can I get prototypes?

The sample lead time is listed on the ordering page. It depends on the part and is confirmed in the quote.
