Radii
In CNC machining, sharp internal corners on a workpiece will naturally form rounded corners (radii). The depth must not exceed 12 times the diameter of the drill. For end mills, the depth must not exceed 10 times the diameter of the tool.
Threads and Tapped Holes
Diameter Φ 1.5-5 mm, depth: 3 times the diameter.
Diameter Φ 5 mm or larger, depth: 4-6 times the diameter.
Adummer can produce threads of any specification and size as required by the customer.
Undercuts
Square profiles, full radius, dovetail profiles.
Text
CNC Milling: Minimum width of 0.5 mm and depth of 0.1 mm.
CNC Turning: RapidDirect can use laser marking to create standard text for CNC turned parts.
Adummer can create standard text via CNC engraving or laser engraving as per customer requirements.
