Gurutzpe GL 10

The Gurutzpe GL 10 is the smallest size of the GL flat-bed lathe: Ø 1,000 mm (39.4 in) of swing over the bed, Ø 700 mm (27.6 in) over the carriage, up to 8 m (26.2 ft) between centres and a part weight of 5 t (11,023 lb). Gurutzpe lists four GL sizes, and this one has the fastest headstock of them, with a speed range of 0-1,400 rpm.

That speed figure carries a footnote. Gurutzpe marks it as a peak speed for 10 minutes and gives the maximum continuous speed as 60% of peak, so long finishing passes on small diameters should be planned around the continuous figure, not the headline one. The power row reads 22/28 kW (29.5/37.5 hp) for S1/S6, followed by a second pair in square brackets, 28/34 kW (37.5/45.6 hp). The torque row is built the same way: 2.7/3.3 kNm (1,992/2,434 lb-ft), then 3.4/4.2 kNm (2,508/3,098 lb-ft) in brackets. The page does not say what the brackets stand for, so ask Gurutzpe which headstock a quotation is based on.

The bed is a monoblock casting with a V-shaped self-centring double guide, hardened and ground, plus a third support guide. Guiding is hydrodynamic. The carriages slide on Biplast material over an oil film fed by centralised lubrication, and the structure is stabilised GG30 cast iron.

Bar throughput is Ø 130 mm (5.1 in), and the GL 10 is the only size whose table gives a single part weight instead of a choice. A Y axis, a motorised head for milling and drilling, integrated measurement and an integral fairing are all named as possibilities or options. None of them belongs to the basic lathe, and the page states no figures for them.
