FAQ
Chiusa
What is a T-Type Ram Boring machine and what makes it different from other configurations?
A T-Type Ram Boring machine is configured with a mobile table (X axis), mobile headstock vertical movement (Y axis), mobile column (Z axis), mobile headstock ram (V axis), and a mobile boring spindle (W axis). This multi-axis architecture enables controlled internal machining with extended reach and precise positioning across the full working envelope.
Compared to T-Type Boring without ram, it enables deeper boring through combined V+W travel up to 2,000 mm. Compared to Floor-Type Ram Boring, it is designed for medium-scale components from 15 to 60 tons.
Unlike systems using linear guides with partial hydrostatic damping, LAZZATI integrates full hydrostatic architecture, ensuring zero-wear motion and stable performance over decades.
T-Type Ram Boring machines integrate LAZZATI hydrostatic technology as standard.
Why choose T-Type Ram Boring instead of T-Type Ram Milling or Floor-Type configurations?
Compared to T-Type Ram Milling, it is dedicated to internal machining rather than external milling operations. Compared to Floor-Type configurations, it is optimized for medium-sized components while maintaining precision, with vertical travel up to 4,000 mm and combined ram and spindle travel up to 2,000 mm.
This configuration aligns machine capability with applications requiring stable and repeatable internal boring.
How does the ram extension support precision boring on complex components?
With table travel up to 7,000 mm and vertical headstock movement up to 4,000 mm, the machine provides controlled access to complex geometries. LAZZATI DCS compensates structural deviations during extension, while the hydrostatic system maintains consistent rigidity across all axes.
How is accuracy maintained during extended ram boring operations?
With component capacities from 15 to 60 tons and vertical travel up to 4,000 mm, the machine maintains stable positioning throughout the working envelope. This enables consistent alignment and repeatability in applications such as aerospace components, defense housings, and compressor casings.
What components are typically machined on T-Type Ram Boring machines?
T-Type Ram Boring machines are used for precision internal machining of medium-scale components across multiple industries. Typical applications include aerospace structural components, defense equipment housings, turbine parts, compressor casings, and oil & gas valve bodies.
Models such as HB 130MT, HB 150MT, HB 160MT, and HB 180MT Evo4.0 cover component capacities from 15 to 60 tons. With boring spindle diameters from Ø130 to Ø180 mm and combined V+W travel up to 2,000 mm, these machines support deep internal machining while maintaining controlled geometry.
Precision, rigidity and reliability define their role in consistent industrial performance.
