The typical marking depth of a scribe marking machine can vary depending on several factors, including:

· Material Hardness: Harder materials, such as metals and ceramics, generally require deeper marks than softer materials like plastics.

· Stylus Tip: The type and size of the stylus tip will also affect the marking depth. Carbide and diamond tips can produce deeper marks than softer materials.

· Machine Settings: The pressure applied by the stylus and the speed of the machine can also influence the marking depth.

In general, scribe marking machines can produce marks ranging from a few thousandths of an inch to several hundredths of an inch deep. The exact depth can be adjusted to meet specific requirements.
