Index Corp. has developed a second generation of turn-mill centers, the G200, a compact machine offering up to as much as 30-percent higher productivity—in the same footprint as the previous generation. The redesign of the machine resulted in an increase of the maximum turning length to 660 mm, a higher performance milling spindle and an expanded live tool complement as well as the XPanel control panel.
The machine offers flexibility and high-speed machining of both barstock and chuck parts complete in one setup. The machine bed is arranged vertically, making the machine stand higher, but extending in the work area, thus permitting a second lower tool carrier to increase the productivity of the machine.
The fluid-cooled main and counterspindles are designed identically and feature a bar capacity of 65 mm (chuck diameter max. 165 mm). Their motorized spindles allow a productive turning machining with a power of 31.5/32 kW (100 percent/40 percent duty cycle), a torque of 125/170 Nm and a maximum speed of 6,000 rpm.
The G200 has three tool carriers so tools can be assigned to almost any machining type on the main and counterspindles independently. This means great flexibility for the programmer in organizing the machining steps.
Because of the large work area, it is even possible to work with three turrets simultaneously on the main spindle or counterspindle, without them interfering with each other. The 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.
The company’s Xpanel i4.0 ready control concept facilitates the handling of the control. Numerous control elements of the machine operating panel have been integrated into the screen, where they can be operated directly on the 18.5” touchscreen with visual support.
