LAZZATI History: A Century of Engineering, Continuity and Evolution
From the Rovai family heritage of 1921 to the 1939 foundation of LAZZATI, our history reflects engineering competence, hydrostatic innovation and four generations dedicated to precision machining.
Lazzati history
Our Dual Heritage: 1921 and 1939
1921 – The Rovai Family's Engineering Origins
1939 – Foundation of LAZZATI in Legnano (Milan)
1954 – When the Two Stories Become One
1954–Today
Timeline of Innovation
LAZZATI’s philosophy is built on concrete principles:
Launch of HB 80
High-performance boring mill with rapid feed up to 1,000 mm/min.
HB 76 with Hydraulic Automation
Compact boring mill equipped with advanced hydraulic control systems.
Acquisition of Bordiga (Turin)
Integration of planer and planer-type milling expertise, expanding LAZZATI’s structural know-how.
Modular Platforms HB 100–115–127
First LAZZATI CNC Machine: HB 130MT
Hydrostatic Engineering by Ing. Renato Rovai (3rd Generation)
New Assembly Plant in Rescaldina
HB 5M Hydrostatic Milling-Boring Line
Among the first hydrostatic mobile-column milling machines with full RAM and milling head movement.
Complete Relocation to Rescaldina
LAZZATI consolidates all operations in the current headquarters; full CNC-based production.
First Automatic Universal Milling Head (1° × 1°)
LAZZATI develops its first automatic universal milling head with 1° × 1° indexing, expanding multi-axis machining capabilities.
First Standard Production of the T-Type Architecture
1986–2010
Hydrostatic Consolidation and Mechatronic Development
100% Rovai Family Ownership
Development of the DCS (Dynamic Compensation System)
Development of the TCS (Thermal Control System)
Thermal stabilization system designed to eliminate temperature-induced drift during long machining cycles.
Development of L-DAS (LAZZATI Dynamic Axis Setup)
New Assembly Hall for Large Machines
Digital Transformation and Modern Hydrostatic Architecture
Early Mechatronic and Digital Systems
BlueTech4.0 Regeneration Program
Consolidation of the LAZZATECH Platform
Today – Fourth Generation at the Helm
LAZZATI is led by Renato Rovai (CEO & President) together with Manfredi Rovai and Marianna Rovai (4th generation), combining a century of family engineering heritage with advanced hydrostatic technology and modern digital systems.
Made in Italy, Engineered for Value
Every machine is designed, manufactured and tested in our Rescaldina headquarters. A tradition dating back to 1939, strengthened by the Rovai family’s engineering heritage since 1921.
Engineered to last. Built to perform.
Hydrostatic excellence since 1939.
LAZZATI S.p.A. traces its heritage to the Rovai family’s machine-tool manufacturing legacy beginning in 1921, merged with LAZZATI’s foundation in 1939 in Legnano, Milan. For over 85 years, LAZZATI has been designing and manufacturing hydrostatic CNC boring, milling and multitasking machines, with four generations of the Rovai family at the helm. The company’s evolution from early mechanical designs through CNC development (HB 130MT, 1972) to hydrostatic engineering (1975) and modern T-Type architecture (1988–1990) reflects continuous innovation. Key technology milestones include the DCS (Dynamic Compensation System, 1992), the TCS (Thermal Control System, 2001), and the L-DAS (LAZZATI Dynamic Axis Setup, 2006), culminating in the integrated LAZZATECH platform (2020–2025). Today, under the leadership of Renato, Manfredi, and Marianna Rovai (4th generation), LAZZATI represents Made in Italy engineering excellence, combining hydrostatic precision, structural rigidity, and digital Industry 4.0/5.0 integration. Ideal for aerospace, energy, oil & gas, heavy fabrication and precision engineering sectors, LAZZATI machines deliver investment-grade reliability and lifetime accuracy maintained through proprietary systems and comprehensive LO&M support.
