INDEX Corporation has introduced its new C200 series of production turn-mill centers with a choice of the FANUC 31i CNC option or Siemens 840D CNC. The INDEX C200 is available in two spindle sizes for 65 mm and 90 mm bar capacity for the main and counterspindles. Three driven tools from the machine's 42-tool complement can be on the work simultaneously.
The C100 is designed for bar work between 30-42 mm and features higher speed spindle (9,000 and 8,000 RPM) and counter-spindles (7,000 RPM).
"With three 14-position tool turrets, 160 mm chuck size and identical powerful main and counter spindles, the space-saving INDEX C200s are designed for fast, cost-competitive production of medium complexity parts turned from 65-90 mm diameter bar stock in the automotive, fittings, fluid power and medical industries," said a company spokesperson. "Ideal for small to medium lot sizes, the machines deliver high performance utilizing a small amount of floor space, and are targeted to handle fixed headstock work often run on Swiss-type machines. Users can expect high machine utilization rates, which allow the machines to be cost-effective.
"Each position on the 14-station turret is equipped for driven tools. The C200 includes a tooling capacity of 42 quick change tools, fixed and driven, higher horsepower and greater torque but with the RPM typical of Swiss-style machines. Large tooling capacity means short set-up times and fast cycle times - even for small batches. Turrets feature 30 MPM rapid traverse for quick positioning.
"Tools are more easily accessible than on a Swiss machine and can be changed quickly. They lock with only one screw and feature an INDEX W serration, and INDEX-specific improved VDI interface which ensures repetitive accuracies of +/- 8 microns up to 100 mm from the mounting surface."
The C200 with 65 mm bar capacity comes with 5,000 RPM spindles and the 90 mm bar capacity is available with 3,500 RPM spindles. Both versions can run parts to 200 mm in length. The C200 drives are 25/33 kW and 23/31 kW (100% / 40%) for the 65 mm and 90 mm versions. Motorized main and counter spindles are identical and liquid cooled.
Up to three tools can be at work simultaneously with both Y axes and backworking at the same time. The counterspindle with a driven Z-axis can be synchronized with travel of turret 3. Counter spindle pick-up from the main spindle is accomplished in 1.5 seconds.
Simultaneous machining with two Y axes, one at the main spindle and one shared between the main spindle and the counter spindle and each with 70 mm travel, gives users the option to divide machining operations for enhanced machining efficiency and flexibility. According to the company, this freedom also is a key to reduced cycle times. For example, users can machine simultaneously with up to three tools simultaneously, driven or fixed, for complete machining in a single set-up, including heavy milling and backworking.
The turret slides move in the X and Z directions on the INDEX SingleSlide plate type slide system. This system permits rapids up to 60 m/min and accelerations up to 1 g with enhanced rigidity. The plate-type guide way of the turret slides also means turrets glide directly on the machine bed, assuring high stiffness and dampening, resulting in longer tool life and better surface finish, according to the company.
The open work area and vertical-bed machine design permits clear chip fall.
The FANUC CNC features plain text in display and operation and the screen shows all spindles and axes at one view. Programming with more than 70 user routines offers practical support. Index programming is designed to contribute to optimum machine utilization and maximum productivity.
The control includes:
- Machine control panel with TFT color display (10.4")
- Electric handwheel in series
- Display of actual axis position values and target/actual value differences, current feed rate, spindle speed, G functions, main program and subprogram numbers
- Total quantity counter, number preset for batch size
- Multi-channel editor and program display.
