Tacchi HD-1450 X 4M Large Spindle Bore Lathe

About this machine

The Tacchi HD-1450 X 4M is a used lathe — sometimes referred to as a turning machine — designed for heavy-duty material removal and precision turning operations on large workpieces. Lathes of this class are central to industries such as oil and gas, power generation, shipbuilding, and heavy engineering, where oversized components require accurate cylindrical turning, boring, facing, and threading. Tacchi is an Italian manufacturer with a long-standing reputation for building large and heavy-duty machine tools, particularly gap-bed and heavy-turning lathes suited to demanding industrial applications.

This machine is offered in used condition and is located in the United Kingdom. It was manufactured in 2002 and is equipped with a Siemens CNC control system, bringing programmable precision to what is a substantial heavy-turning platform.

The scale of this lathe is defined by its key capacity figures. The swing over the bed measures 1,450 mm, while the swing over the saddle is 1,000 mm, indicating the maximum diameter of workpiece that can be rotated above each respective surface. A particularly notable feature is the hollow spindle bore of 515 mm, which allows long bar stock or large-diameter tubular workpieces to pass directly through the headstock — a critical capability for pipe, sleeve, and cylindrical component work. The machine supports a workpiece weight of 15,000 kg between centres, confirming its suitability for very heavy industrial parts.

The spindle speed range runs from 1.5 to 450 rpm, providing a wide spread from very slow rotation for heavy facing passes on large-diameter workpieces through to higher speeds for finishing operations on smaller diameters. The headstock is configured with chucks at both the front and rear, offering additional flexibility in workholding and workpiece support arrangements.

Tooling and workpiece support equipment is included with the machine. A Baruffaldi four-way automatic toolpost is fitted, allowing multiple turning tools to be indexed automatically under CNC control for efficient multi-operation work. Two three-point steadies are also included, which are used to support long or slender workpieces at intermediate points along their length, reducing deflection and vibration during cutting.
