Drilled Sheets

The production process

Punching is the standard method for manufacturing perforated sheets; in case such working process cannot be applied, i.e. where the hole diameter is smaller than the plate thickness, it is possible to perforate the sheet by drilling or milling it.

Hole | There are three types of hole that may result from a process of drilling:

Cylindrical
Bi-cylindrical
Conical
Conical-Cylindrical
This technology allow perforation with small holes and pitches on materials
whose thickness is bigger than 50 mm .

Materials | The materials that are commonly worked with this technique are: Carbon steel, stainless steels, Hardox, titanium, chromium-nickel alloys, aluminium , copper and the relevant alloys.

Sheets | Characteristics of sheets we worked:

Dimension (mm)
Thinkness of sheets (mm)
2000×6000
From 1 to 100
3000×8000
From 1 to 100
Finish | After the drilling process we can also carry out special surface finishings such as lapping,
glazing, electro-polishing and washing in order to assure a perfect cleanness of
the holes.

To obtain an estimate indicate:

1)  Type and quality of material, thickness and size of the waterjet plates.
2)  Requested quantity and kind of perforation.

4) Tollerance and type of finishing of finishing of the sheets
3) Drawing in DWG file if available.
