Galbiati Group recently realized a deep hole drilling machine with two spindles for the manufacture of shell and tube heat exchangers for the nuclear industry. The construction of these machines required significant engineering development to hold the close tolerances required for this type of application.

The deep-hole drilling machine, equipped with the BTA drilling system, is intended for the deep-hole drilling of heat exchangers tube plates up to a diameter of 51.7 mm.

The two spindles- deep hole drilling machine in question also has a third spindle for additional processes like milling of the workpiece or drilling of the same using tip inserts up to 80 mm in diameter, with an automatic system for locking/releasing the tool on the spindle.

Below are photos of the two spindles- deep hole drilling machine in the assembly area of Galbiati Group’s workshop.

We have recently realized deep-hole drilling machine with 2 spindles for the deep-hole drilling of tube plates for STS/BTA single tube sheet heat exchangers up to a diameter of 51.7 mm.

The BTA deep-hole drilling system has a drill chuck tube instead of the conventional longitudinal groove of lip drills. This greatly improves the cutting speed and travel of the tool and makes it about 4-6 times more productive than the Gundrill system.

The two spindles- deep hole drilling machine in question also has a third spindle for additional processes like milling of the workpiece or drilling of the same using tip inserts up to 80 mm in diameter, with an automatic system for locking/releasing the tool on the spindle.

The final test was carried out in the assembly area of Galbiati Group’s workshop, at the presence of the customer, and to the full satisfaction of both parties.

Below are photos of installation of the two spindles- deep hole drilling machine on the customer’s premises in Africa.

We are specialized in the design and construction of drilling machines equipped with 2 or 3 spindles for deep drilling such as BTA (STS) and GUNDRILL types for tubal sheets with heat exchangers.

In the below you will see the testing phase of a drilling machine with 2 spindles for deep drilling of heat exchangers with a single STS/BTA tubular system, for up to 51.7 mm in diameter.

The deep hole drilling machine is also equipped with a third spindle for additional processes such as milling or drilling with drill inserts up to a diameter of 80 mm with an automatic system for locking / releasing the tool on the spindle. The final test was performed at the mounting area of the Galbiati Group workshop with the satisfaction of both parties and in the presence of the customer.

Indipendent spindle drilling machines for BTA (STS) deep drilling and Gun Drilling heat exchanger tube sheets.

Galbiati has built deep hole drilling machines with two independent spindles for the manufacture of shell and tube heat exchangers for the chemical and petrochemical industry. The machine is equipped with Siemens Sinumerik 840D 5-axes numerical control.

These machines can be equipped with an optional milling spindle, highly useful for finishing operations on the tube sheets (baffles, grooves, flares, tie-rods), avoiding the use of other machines.
