The production departments contain 38 machines, including Automatic Multi-Spindle Lathes and CNC Turning Centres, available capacity from 3 mm diameter up to 65 mm diameter, up to 100k pieces a day depending on the complexity of the machining processes.
- Turning
Material removal machining process by means of lathes equipped with special tooling: cylindrical, conical, plain or surface turning. Turning may also consist of a drilling, reaming, threading or contouring process; sometimes it may be milling or grinding.
- Threading
Surface material removal machining process used to create a helical ridge on the metal piece (external threading) or a helical groove (internal threading).
- Milling
Material removal process capable of producing a vast range of surfaces, including planes, grooves and shoulders, using a multi-edge tool of a specific shape.
- Roll-Finishing
A pressure rolling procedure carried out to improve the surface finish or to create a tougher thread than could be obtained by turning, since this method induces more hardening in the material.
- Precision grinding and honing
Machining process which reduces mainly cylindrical or spherical objects to the same diameter.
- Knurling
A procedure that uses pressure to create grooves and ridges in a chequered or diamond pattern on surfaces. It is used on coins or mechanical pieces such as regulator knobs, crank handles, etc. to give them a rough surface that offers a firmer grip.
- Polygon turning
Material removal machining process which produces square or hexagonal parallel planes on the outside of light alloy pieces.
- Marking
A process which uses pressure to mark the metal piece.
- Broaching
Creation of grooves and teeth inside holes in metal parts for machining (internal broaching) or shaping of the external profile (external broaching). This process is able to produce square, elliptical and hexagonal holes, splines and even very complex contours.
- Drilling
Surface material removal machining process carried out to create a hole, which may include the following phases: - centring (alignment with the axis of the hole); - drilling; - widening (increasing the diameter of the hole); - reaming (finishing of the hole).
- Boring
Material removal process which increases a diameter with precision finishing in terms of both roughness and tolerance.
- Reaming
Operation which finishes the surface of a cylindrical hole using a multi-edge tool.
- Knurling
A procedure that uses pressure to create grooves and ridges in a chequered or diamond pattern on surfaces. It is used on coins or mechanical pieces such as regulator knobs, crank handles, etc. to give them a rough surface that offers a firmer grip.
Other machining processes:
Hobbing, die threading, threading with chaser dies, roller threading, deep drilling, radial drilling, end milling, radial milling, honing, tapping, deburring, grooving, flaring and parting.
