Our services include 3-Axis CNC milling, 3D surface machining, CNC turning, drilling, reaming, tapping, thread milling and more. More details can be found on our Services page.

For milling: 300x220x150mm

For turning: ⌀70x120mm

General tolerances: by default, we offer 3 different general tolerance levels (±0.10mm, ± 0.07mm, ±0.05mm). 

Tight tolerances: we are capable of holding the tight tolerances where you require them (a 2D drawing is required). Sometimes when a part is more complex, it can add some lead time to the order. We will still get it out in a timely fashion.

  • Font engraving: minimum stick width of 1 mm and a maximum depth of 0.3 mm.
  • Gorges, pockets and rounded corners: minimum size: 1mm
  • minimum radius for convex corners: 1mm
  • Punctures: maximum depth of 7 times the diameter, if a hole is joined to a wall the length will start from the edge of the wall itself.
  • Walls: minimum thickness of 1mm.
  • Threads: maximum depth of 7 times its diameter. If a hole is positioned next to a wall, length starts from the edge of that same wall. On blind holes, threading is done up to a maximum of 3/4 of the hole depth.

Yes. If there are threaded or reamed holes in your part, please indicate it your quote request and include a 2D drawing with details.
