Makino V99L (50 Taper)

The Makino V99L (50 Taper) is a heavy vertical with a 30 kW (40 hp) CAT50 spindle at 10,000 RPM, HSK-A100 optional, working over 1,300 x 1,000 x 500 mm (51.2 x 39.4 x 19.7 in) of travel and a 1,500 x 1,000 mm (59.1 x 39.4 in) table. The machine is not in Makino's current lineup and looks like an older model; its figures come from the listed table and are not confirmed by Makino.

This is the version for big tools on big plates. Tools can be 5.7 in across and 44 lbs, the table takes 3,000 kg (6,614 lb), and through-spindle coolant is standard. Tool-to-tool time is listed as 5 secs. The magazine holds 30, with 40 and 60 as options; 50-taper tools of the maximum diameter usually block the pockets beside them, so the usable count can be lower.

Compared with the current Makino F9, which has a 10,000 rpm CAT50 spindle with HSK-A100 optional, the trade-off is clear. The Makino F9 has 1,600 mm (63 in) of X, 800 mm (31.5 in) of Y and 650 mm (25.6 in) of Z on a 1,850 x 800 mm (72.8 in x 31.5 in) table. The V99L (50 Taper) gives up X and Z for 1,000 mm (39.4 in) of Y, which favours wide square plates over long or tall parts.

Rapids are 36 m/min (1,417 ipm) in X and Y and 30 m/min (1,181 ipm) in Z on roller-type linear guides. The machine weighs about 16,500 kg (36,376 lb) and uses the Makino Professional 6 (Pro 6) control. Two rows need explaining before purchase: a pallet of 2,300 x 1,000 mm is listed, larger than the table, and a second spindle row gives 12,000 RPM with an 18,000 option.
