RatioLine R300 Turning/Milling Center

With the R series, INDEX is setting the standard for a new generation of turning/milling centers. Two motorized milling spindles perform machining in two independent sub-systems, including 5-axis machining. Both heavy-duty roughing operations and highly accurate fine-turning operations can be performed simultaneously on the main spindle and counter spindle. This parallel use increases productivity significantly compared to conventional designs. New design solutions for optimum stiffness, thermal and dynamic stability, and vibration damping also provide for maximum machining quality.

Two milling spindles are used simultaneously and independently Complete machining • Separate subsystems for upper and lower motorized milling spindles, allowing full rear end machining or parallel machining • Simultaneous 5-axis machining on both spindles possible • Generous tool memory for high flexibility • Tool strips with a total of 12 stationary tools permanently in the working area Speed • Parallel machining with 2 milling spindles • High accelerations and rapid traverse rates • Typical chip-to-chip time of only 6 seconds for automatic tool changing • Short traversing distances in a...

Due to intelligent kinematics with an efficient arrangement of axes, a trendsetting machine concept has emerged that also facilitates comprehensive complete machining operations. The idea: A vertical machine arrangement in which the main spindle moves in the Z direction, the counter spindle in the X and Z directions, tool carrier 1 in the X, Y, and B directions, and tool carrier 2 in the Y and B directions. The result: A design with two independent sub-systems, exceptional stiffness between moving components and machine bed, as well as impressive dynamic response. Consequently, the...

During development of the R series, emphasis was placed on achieving a high degree of stiffness, thermal and dynamic stability, and vibration damping. For this reason, a vertical cast machine bed with a heavily ribbed, en-closed modular design was chosen. The motorized milling spindles are placed in the center of the machine and are operated freely and wear-free in the Y- and B-axes via hydrostatic circular guides. The guide system contributes considerably to the machine's enormous stiffness. Optimum force transmission is another premise that was implemented consistently. The short lever...

Two separate shuttle units independently supply the two motorized milling spindles with the tools required in each case from the tool magazine. With a maximum of 140 tool pockets, the R300 has a large tool set. Chip-to-chip time of 6 seconds contributes to minimizing secondary processing times. 1. Transverse shuttle for removal of tools from chain magazine 2. Handover from transverse shuttle to longitudinal shuttle via double gripper 3. Loading position of tool for milling spindle At a glance • 70/140 tool stations (HSK-T63 holder) • Minimum load cycles; Chip-to-chip time only 6 s •...

For years, INDEX has viewed the efficient use of energy and resources as a key requirement in its machine development activities. Therefore, today all machines already conform to the principle of reduced energy consumption with simultaneous improvement in environmental compatibility. Design experience, such as measurements on machines in the field, form the basis for meeting or even surpassing requirements regarding energy/resource efficiency sustainably, also in the future. Weight reduction: • Reduction of energy consumption Simulation programs enable minimization of weights of moving...

Reliable handling The INDEX C200-4D SL control is based on the field-proven SIEMENS SINUMERIK S840D Solution Line, paired with drives from the SIEMENS SINAMICS series. INDEX enhanced this field-proven C200-4D SL control with additional user-friendly functions. These specially designed machine and machining cycles make even the most complex machining operations available with ease. They support high-efficiency multi-axis milling and turning operations and provide maximum functional reliability. The result is a control that is designed to meet the machine operator's needs. Simple tool...
