Our best estimate for a cnc lathes / turning center in this class — not a quote from INDEX-Traub. Configuration moves it a long way.

Overview

The INDEX G220 Plus is a turn-mill center with a 500 mm swing over the bed, a Y-axis stroke of ±60 mm and 660 mm (26 in) of turning length. Those three rows are what its table adds over the plain specification sheet shared across the G200 and G220 family, and they describe a machine set up for off-centre milling and drilling as much as for turning.

A ±60 mm Y stroke means flats, slots, bolt-hole patterns and cross holes can be placed well away from the spindle centreline without indexing the part. Driven tools on HSK-A40 run to 7,200 rpm with 9 kW and 16 Nm, so this is the right machine for many small milled features rather than heavy pocketing. The turret has 12 positions.

The main spindle runs to 6,000 rpm on a 165 mm (6.5 in) chuck and takes 65 mm (2.6 in) bar. It is rated 20 kW continuous and 24 kW at 40% duty, with 125 Nm continuous, 170 Nm at 40% duty and 207 Nm maximum. The sub spindle runs to 5,000 RPM. The sibling G220 lists its counter spindle at 6,000 RPM, so if second-side speed matters, check which version is being quoted.

X travel is 230 mm (9.1 in) and Z travel 845 mm (33.3 in), with rapids of 30 m/min and 50 m/min. The tailstock row also reads 845 mm (33.3 in).

On site, the G220 Plus needs a footprint of 5355 × 2235 × 2400 mm (L × W × H), a foundation for approx. 8,500 kg (18,739 lb) and a 42 kW supply. It runs a Siemens S840D sl control.

Strengths & Limitations

Strengths

Y-axis stroke of ±60 mm for off-centre milling and drilling
500 mm swing over the bed
207 Nm maximum spindle torque, with 170 Nm at 40% duty
12-position turret with driven tools at 7,200 rpm on HSK-A40
660 mm (26 in) turning length and 845 mm (33.3 in) of Z travel

Limitations

Sub spindle runs to 5,000 RPM, below the 6,000 rpm main spindle
Driven tools are rated 9 kW and 16 Nm, light for heavy milling
Bar capacity is 65 mm (2.6 in)
A 12-position turret limits tool count on parts with many operations

Best For

Parts with off-centre holes, flats and slots within ±60 mm Bar work up to 65 mm (2.6 in) with milled features Turned and milled shafts up to 660 mm (26 in) long Parts that need a 500 mm swing over the bed

Frequently Asked Questions

01 How much Y-axis travel does the G220 Plus have?

The Y-axis stroke is ±60 mm. That allows milled and drilled features to sit well off the spindle centreline. Driven tools for that work run to 7,200 rpm with 9 kW and 16 Nm on an HSK-A40 interface.

02 What is the swing of the G220 Plus?

The swing over the bed is 500 mm. The chuck is 165 mm (6.5 in) and bar capacity 65 mm (2.6 in), and X travel is 230 mm (9.1 in), so check the actual turning diameter for your part with INDEX rather than relying on swing alone.

03 How fast is the G220 Plus sub spindle?

The sub spindle runs to 5,000 RPM. The main spindle reaches 6,000 rpm with 20 kW continuous and 24 kW at 40% duty. The G220 table gives its counter spindle 6,000 RPM, so confirm the second-spindle speed for the version quoted.

04 What does the G220 Plus need for installation?

Floor space of 5355 × 2235 × 2400 mm (L × W × H), a foundation for approx. 8,500 kg (18,739 lb) and a 42 kW supply. Add room for a bar loader if the machine will run from bar.
