With the guillotine shear, sheets with a thickness of 1-6 mm and a length of up to 4 m can be cut quickly and efficiently.

Programming of all shapes and contours from electronic data, plans or hand sketches. Cutting of workpieces made of steel, stainless steel or aluminium without mechanical stress and without tooling. Laser cutting is extremely interesting from an economic point of view.

Precise bending of complicated bent parts on 2 different bending presses. Bending lengths of up to 6 metres and maximum press forces of up to 600 tonnes are possible. Individually programmable bending sequence. Flexible solutions and fast order processing even for small series thanks to short changeover times.

Sheet metal up to 8 mm thick and up to 2 m wide can be rolled on the Aerni rollers.

We are specialised in the production of individual parts through to series production. Enquire with us without any obligation.

Turning work on conventional or computer-controlled cycle lathe up to ø 750 mm with lengths up to 3200 mm as well as on CNC-controlled double spindle lathe with short bar loader for complex individual parts and series up to ø 270 mm, centre distance 800 mm.

Milling work depending on the number of pieces conventionally up to x = 1050 mm, y = 450 mm, z = 545 mm or by CNC machining centre up to x = 1500 mm, y = 660 mm, z = 660 mm.

We are specialised in the production of individual parts through to series production. Enquire with us without any obligation.

All welding work in aluminium, steel, stainless and acid-resistant steel and Hastelloy. Whether construction parts for manual welding, rotationally symmetrical parts for automatic circular welding or complex series parts – all welding processes such as TIG, MIG and MAG can be used.

Spot welding of various materials such as steel, stainless steel and aluminium. Stainless steel can also be gassed to avoid tarnishing.

Stud welding: Efficient welding of threads up to M12.

Aerni’s grinder operators are specialists in the manual grinding of plant components, pressure vessels and sheet metal constructions. The required roughness can be checked and documented with our own calibrated measuring instruments. 

If desired, the grinding work can also be carried out at the customer’s site. The grinder operators bring the necessary grinding tools and machines with them. Enquire with us without any obligation.
