How much does the Geminis GT9i-G2 cost?

Price estimate

Uncertain

We do not have a price for the Geminis GT9i-G2 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

The Geminis GT9i-G2 is a large horizontal CNC lathe whose capacity rows are ranges instead of single values: swing over the bed from 2,000 to 2,600 mm (78.7 to 102.4 in) and swing over the carriage from 1,600 to 2,200 mm (63.0 to 86.6 in). One model name therefore covers several sizes of machine, and the swing has to be fixed when the lathe is ordered.

Maximum workpiece weight is listed as 25,000 / 60,000 kg (55,115 / 132,275 lb). The table does not tie either weight to a particular swing, so a quotation should state the swing over bed, the swing over carriage and the weight rating together.

Its neighbours mark the edges. The GT7i-G2 stops at 1,800 mm (70.9 in) over the bed and 25,000 kg (55,115 lb). At the other end the GT11i-G2 starts at 2,600 mm (102.4 in), the top of this model's range, and lists 45,000 / 150,000 kg (99,206 / 330,688 lb). For a part that needs 2,600 mm of swing, weight decides between the two.

The bed has 2 upper guides Box Type with 1 front guide protected from chips, the headstock has 4 speed ranges with automatic changeover, and double chip conveyors are optional.

Strengths & Limitations

Strengths

Swing over bed can be specified anywhere from 2,000 to 2,600 mm (78.7 to 102.4 in)
Up to 2,200 mm (86.6 in) of swing over the carriage for long, large-diameter work
Upper workpiece weight figure of 60,000 kg (132,275 lb)
4 speed ranges with automatic changeover and main shaft oscillation

Limitations

Capacity figures are ranges, so two GT9i-G2 lathes are not necessarily the same size; check the as-built swing of any specific machine
At the low end of the range the swing over carriage is 1,600 mm (63.0 in)
Chip evacuation needs the optional double conveyors
The table lists no spindle power, torque or speed for a lathe rated to 60,000 kg (132,275 lb)

Best For

Rolls and shafts from 1,600 to 2,200 mm (63.0 to 86.6 in) in diameter over the carriage Workpieces above 25,000 kg (55,115 lb) and up to 60,000 kg (132,275 lb) Shops that want the swing matched to a known part family at order Long parts within the 1 - 24 m (39.4 - 944.9 in) length range

Frequently Asked Questions

01 Why does the GT9i-G2 list a range for swing?

Because the model is built in more than one size. Swing over bed runs from 2,000 to 2,600 mm (78.7 to 102.4 in) and swing over carriage from 1,600 to 2,200 mm (63.0 to 86.6 in). The buyer chooses within those limits, and the figure chosen is what the finished machine can turn.

02 When should I look at the GT11i-G2 instead of the GT9i-G2?

When the part is wider than 2,600 mm (102.4 in) or heavier than 60,000 kg (132,275 lb). The GT11i-G2 lists a swing over bed of 2,600 - 3,600 mm (102.4 - 141.7 in) and workpiece weights of 45,000 / 150,000 kg (99,206 / 330,688 lb).

03 What is the heaviest part a GT9i-G2 can hold?

The listed figures are 25,000 / 60,000 kg (55,115 / 132,275 lb). Geminis's table gives both without saying what separates them, so the rating that applies to a given swing and support arrangement needs to be confirmed for the machine actually quoted.
