Hydrostatic CNC Floor-Type Ram Boring Machines

A Floor-Type Ram Boring machine is a CNC system with moving column, mobile ram, and a dedicated boring spindle designed for deep internal machining operations. Unlike Floor-Type Ram Milling, it is focused on deep internal boring rather than external finishing. Compared with T-Type Ram Boring, it operates on a larger scale, handling components up to 40 meters and more in length, 100+ tons and beyond, and vertical travel up to 7,000 mm. Unlike systems using linear guides with partial hydrostatic damping, LAZZATI integrates full hydrostatic architecture across all axes, ensuring zero-wear motion and stable performance over decades. It supports deep boring depths exceeding 2,000 mm and diameters up to Ø2,000 mm+. Floor-Type Ram Boring machines integrate LAZZATI hydrostatic technology as standard.

Floor-Type Ram Boring is selected when applications require deep internal boring, large-diameter precision holes, and extended vertical reach. Compared with Floor-Type Ram Milling, it is designed for internal machining rather than external surface finishing. Compared with T-Type configurations, it supports larger components, typically up to 40 meters and more in length, 100+ tons and beyond, and vertical travel up to 7,000 mm. This makes it suitable for turbine shafts, generator housings, hydroelectric components, and large valve bodies. The configuration aligns with applications where internal geometry control, deep boring capability, and vertical accessibility are critical.

Floor-Type Ram Boring machines are designed for deep internal machining of components such as turbine shafts, generator housings, hydroelectric runners, and compressor casings. Deep boring depths exceed 2,000 mm, combined with vertical travel up to 7,000 mm, enabling machining of large vertical and horizontal structures. The extended ram allows access to internal geometries without repositioning the workpiece. With column travel up to 40,000 mm, the machine supports components up to 40 meters and more and 100+ tons and beyond. This configuration enables controlled machining of long bores and large internal diameters in energy and heavy industry applications.

During deep boring operations, extended ram positions can introduce structural deflection, particularly when machining long bores or large vertical components. DCS compensates these variations in real time, maintaining geometric accuracy throughout the operation. With vertical travel up to 7,000 mm and deep boring depths exceeding 2,000 mm, this compensation is critical for turbine shafts, generator housings, and large valve bodies. The hydrostatic structure supports consistent machine behavior under load, allowing tolerances in the ±0.01 mm to ±0.02 mm range to be maintained across extended machining conditions.

Floor-Type Ram Boring machines are used for gas and steam turbine rotors and shafts, hydroelectric turbine runners, generator housings, stators, large valve bodies, compressor casings, and wind turbine main shafts. These components require deep internal boring, large-diameter precision, and controlled internal geometry. Models ranging from HB 130MM to HB 260MM Evo4.0 support boring spindle diameters from Ø130 to Ø260 mm. The configuration enables machining of components up to 40 meters and more in length, with Floor-Type capacity configurable based on table selection, supporting components weighing 100+ tons and beyond.

Floor-Type Ram Boring machines support deep boring depths exceeding 2,000 mm, large internal diameters up to Ø2,000 mm+, and vertical travel up to 7,000 mm. These capabilities are relevant for turbine shafts, generator housings, and oil & gas components such as valve bodies and pressure vessels. The system operates on components up to 40 meters and more in length and 100+ tons and beyond, depending on configuration. Typical machining tolerances are in the ±0.01 mm to ±0.02 mm range. Precision, rigidity and reliability are maintained across deep internal machining operations.
