CNC Bar Machine has heavy-duty counter spindle.

Press Release Summary:

Capable of simultaneous 3-tool cutting, C65 features Polygon Generating Capability, 2 Y-axes for turrets, and guide-ways for turrets with slides based on plate-type slide system. Turret slides and counter-spindle slide offer 1 g acceleration rate and rapid traverse rates of 75 and 150 fpm. With 1 5/8 or 2½ in. bar capacities, machine offers respective max spindle speeds of 6,300 and 5,000 rpm at 20 kW or 26 hp, 100% duty rating and 77 lb-ft torque.

New Single-Spindle CNC Bar Machine

INDEX Corporation introduces its C65 CNC Single Spindle Bar Machine, continuing a 90-year tradition of building successful single-spindle bar automatics featuring a heavy-duty counter-spindle and Y-axis for extended machining flexibility and increased speed.

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% (60min) duty rating and 105Nm (77ftlbs) torque, the C65 has enough power to do a lot of work in a short time.

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.

According to an Index spokesman, "The new model offers new levels of productivity and flexibility for work done from bar stock. In the past it was either speed or flexibility; with the C- series both goals can be accomplished."

Speed. Three tools are in cut simultaneously almost all the time plus 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. In addition, C65 productivity benefits from higher machining power and higher acceleration and traverse rates.

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 CS42 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.

Despite its large working range, the machine exhibits a compact screw machine size design, requiring little floor space to make sure it fits into every shop that runs screw machines When speed and productivity count, which is the case in a screw machine shop, the C65 will be hard to beat.
