With the new C65 CNC Single Spindle Bar Machine, INDEX continues a 90-year tradition of successful single-spindle bar automatics. The C65 can include a heavy-duty counter-spindle and Y-axis for extended machining flexibility and increased speed. According to Index, the new model offers new levels of both productivity and flexibility for work done from bar stock.

With optional 42mm (1 5/8inch), or 65mm (2 ½inch) bar capacity, a maximum spindle speed of 6300, respectively 5000 RPM at 20KW or 26Hp at 100-percent (60min) duty rating and 105Nm (77ftlbs) torque, the C65 has enough power to do a lot of work in a short time. Despite its large working range, the machine exhibits a compact screw machine size design, requiring little floor space so it fits into every shop that runs screw machines.

Both turret slides and the counter-spindle slide offer a 1g acceleration rate, and rapid traverse rates of 25 and 50m/min (75 and 150 ft/min), adding to the productivity because of its faster motions. These production advantages can often become essential for the survival of a business, particularly for job shops.

Speed: Three tools are in cut simultaneously almost all the time. And a counter-spindle equipped with the usual Z-axis and X-axis allows the user to complete parts very quickly. Both axes are electronically coupled with the second turret (slave- axes). As a result, the third turret can be working on the part in the counter spindle while the other two turrets work on the main spindle, so that three tools may be in cut simultaneously.

Flexibility: Two Y-axes for the turrets and a very powerful counter spindle provide flexibility unmatched by other automatics for machining even complex parts without compromising speed or productivity.

An additional innovation is the polygon generating capability, which results from the counter-spindle operating as a polygon generating attachment. The actual polygon generating head is mounted directly on the face of the chuck. No additional equipment is required. The very high rotational inertia and stiffness of the counter spindle assures vibration-free cuts, as well as long tool life, even on alloy steel.

An innovative highlight of the machine is in the design of the guide-ways for the turrets. The slides are not based on the traditional linear system, but on a highly innovative plate-type slide system. The slide surfaces are made of a match between a cast iron plate, and steel strips with ceramic-coated slides. This slide system offers significant advantages over the traditional slide ways: several times greater stiffness, improved dampening characteristics, and it is more compact. The actual axis drive is accomplished by rod-kinematic drive linkages arranged on the rear of the cast iron machine bed.
