5-Axis Turn-Mill Center INDEX G200The new generation of the turn-mill center is a compact machine offering significantly higher performance – potentially up to 30% greater productivity---in the same footprint as the earlier generation. The redesign of the machine resulted in an increase of the maximum turning length to 660 mm, a higher performance milling spindle, and expanded live tool complement as well as the XPanel with i4.0 readiness.

The G200 is geared to the needs of the market, offering flexibility and high-speed machining of both bar stock and chuck parts complete in one setup.

The machine bed is arranged vertically, making the machine stand higher, but extending the work area,  permitting a second lower tool carrier to increase the productivity of the machine. Reducing cycle times by 30% compared to the first G200 generation is well within the bounds of possibility with appropriate work-pieces.

Fluid-cooled main and counter spindles are designed identically and feature a bar capacity of 65 mm (chuck diameter max. 165 mm ). Their motorized spindles allow productive turning machining with a power of 31.5/32 kW (100%/40% duty cycle), a torque of 125/170 Nm and a maximum speed of 6000 rpm.

The G200 has three tool carriers so tools can be assigned to almost any machining type on the main and counter spindles independently. This means great flexibility for the programmer in organizing the machining steps.

5-Axis Turn-Mill Center INDEX G200Due to the large work area, it is even possible to work with three turrets simultaneously on the main spindle or counter spindle, without them interfering with each other. One example: the lower right turret with an angular tool can machine the inside of a work-piece clamped in the main spindle, while the other lower turret and the upper tool carrier machine the outside. The same is also possible on the counter spindle. This increases the possibilities to use three cutting edges simultaneously, in some cases even 4 tools.

Two 14-tool turrets are arranged in mirror image, each with an independent Y-axis (+/- 45 mm). All tool stations can be equipped with live tools. Tools with internal coolant supply (up to 80 bar) can be used as well.

A special feature is the upper tool carrier, which has an additional Y-axis (+/- 65 mm) and a 360-degree swiveling B-axis. It is designed on one side to provide an added 14 tool positions and has a milling spindle on the rear. Its drive delivers speeds up to 7,200 rpm (power 22 kW, torque 52 Nm at 25% duty  cycle).

The upper turret head can be swung into a horizontal position about the B-axis and then moved into the work area up to a position of 30 mm below the spindle center. In this position, the turret can machine towards the main or counter spindle, or even simultaneously depending on the application. This position is often used to perform face machining with straight tools.
