Dual 5 Axis Milling Machine | INDEX R300 | INDEX TRAUBTwo independent 5-axis subsystems, each with one motorized milling spindle and one assigned work spindle, are able to simultaneously and completely machine complex parts, short bars up to 102 mm and chucking up to 315 mm diameter, providing extreme productivity and flexibility.

The INDEX R300 is geared toward applications where larger chuck parts require a large amount of milling and drilling work, such as machine and farm machinery construction, in tool and mold making or in the aerospace industry.

From very simple to highly complex components, the main benefit is that the complex machining operations are possible simultaneously on the front and rear side – and, at the same time, are highly productive with two motorized milling spindles. The use of HSK tools instead of live tool holders on turrets reduces tool costs.

Ideal for difficult milling operations, the R300 is also capable of hobbing or deep-hole drilling with single-lip tools and high-pressure coolant to 80 bar to the tool edge through the motorized milling spindle. Grinding operations with a grinding point or an external grinding wheel up to 150 mm are additional machining options.

With the addition of tool storage strips, the R300 is well-equipped for highly productive and flexible 5-axis machining, both on the main spindle with tool carrier 1 as well as on the counter spindle with tool carrier 2.

With both linear tool carriers attached to both sides of each milling spindle, the user has quick access to six stationary tools per spindle with high precision. This means that the developers have succeeded in combining the functionality of a turret with a milling spindle. This new development means that tool changes are no longer necessary, thus reducing the secondary processing time during turning. It also makes the production of highly precise fits easier.

Minimal setup times and short secondary processing times

Dual 5 Axis Milling Machine | INDEX R300 | INDEX TRAUBUsers can carry out full rear end machining as well as parallel machining with identical sequences. Both heavy-duty roughing operations and fine-turning operations can be completed simultaneously on the main spindle and counter spindle. A large number of tools (up to 140 tools in the double-chain magazine) ensure short setup times even for small batches. Tool change times are in the 6 sec range.

Added to that are 12 stationary tools on the tool strips of both milling spindles, totaling 152 tools available for a nearly unlimited range of operations and machining flexibility. Both milling spindles can perform tool changes completely independently of one another. The use of HSK tool holders reduces the tool costs as live tool holders are no longer necessary.

The option of operating the machine with a short bar loader with few personnel is only one of several automated handling solutions. For handling heavy chuck parts, an integrated workpiece handling unit is available.
