Deep Hole Drilling Machines for heat exchangers tube plates

Product catalog summary

Overview
The document provides detailed information about the deep hole drilling machines manufactured by the Galbiati Group, specifically designed for drilling tube sheets in heat exchangers used in petrochemical, electric, and nuclear power industries. These machines comply with ASME, TEMA, and PED codes and are available in models with 1 to 5 spindles, utilizing BTA (STS) and Gundrilling systems.

Structure Description
The machines feature a cast iron base and vertical column for dimensional accuracy and minimal deflection. They include hardened sliding ways and a double pre-loaded ball screw wheel nut for precise displacement. The vertical column and drilling unit support are made from rigid electro-welded structures to ensure high rigidity. The displacement detection system uses linear-optical transducers and encoders for accurate positioning.

Strengths
The machines offer high positioning accuracy, repeatability, and precision in bore straightness and concentricity. They feature automatic drilling with advanced control systems for monitoring cutting fluid flow, pressure, axial movement, thrust, and spindle power. The use of Siemens CNC Control systems enhances monitoring capabilities. The design incorporates FEMA for structural stiffness and vibration damping. The machines are modular and customizable, with optional milling units for plate finishing.

Technical Specifications
The machines are available in various configurations, including single and multi-spindle options. Key specifications include:

Drilling depth: 600 mm to 1100 mm
Drilling diameter (STS): 15.5-50.8 mm
Drilling diameter (Gundrill): 10-32 mm
X-axis travel: 3,000 mm – 12,000 mm
Y-axis travel: 1,800 mm – 4,500 mm
Z-axis travel: 600 mm – 1,100 mm
W-axis travel: 600 mm

Quality Assurance
The precision of the structural components is ensured through inspections using a ZEISS MMZ-G 30 60 25 three-dimensional coordinate measuring machine. Major components are machined at the Galbiati Group's plant.
