On-going development continues at Burlescombe-based XYZ Machine Tools (www.xyzmachinetools.com) with the arrival of its seven-machine HD (heavy-duty) range of vertical machining centres.

These VMCs supersede the previous range of box-slideway models in the XYZ range and complement the latest LR (Linear-Rail) machines that have been added.

XYZ says that HD machines allow maximum metal removal rates, thanks to their Meehanite cast beds and columns, along
with induction-hardened ground and Turcite-coated box slideways. X-axis travels extend from 660 to 3,000mm.

The range starts with the XYZ 660 HD, which features increased X- and Y-axis travels of 660 and 450mm yet retains a compact footprint. The other machines in the series are the XYZ 800 HD, 1100 HD and 1510 HD, with three ‘super heavyweight’ machines — the XYZ 2010 HD, 2510 HD and 3010 HD — completing the range.

XYZ says the four smaller HD machines feature increased axis travels, as well as increased spindle power (where deemed necessary).

For example, the XYZ 660 HD now has a 25kW spindle, an increase of 123% over its predecessor. Spindle speed is also improved by 25% to 10,000rev/min; other machines in the range have gained an increase of around 66% in spindle power.

The Siemens 828D ShopMill control featuring a 15in touch screen is fitted as standard, with the control pendant-mounted (on several machines in the range) for further ease of use.

Customers also have a number of options available, such as fourth- and fifth-axis attachments, swarf conveyors and on-machine tool and workpiece probing.
