AUTOMATED TURNING CENTER CELL
Start with its generous A1-15 spindle with a 6.5 in draw tube ID. Perfect alignment and center height are achieved by mounting the headstock on the same way surface as the tailstock. Driving the spindle is a 60 hp motor that transmits power through three gear ranges, ensuring optimal power at speeds from 65 rpm to its maximum 1,500 rpm, and generating low end torque up to 4,873 ft-lb. This maintenance-free digital AC motor accelerates rapidly and is virtually maintenance free.
Tools cut deep into hard-to-machine materials, doing in a single pass what many others do in three or more. Withstanding the stresses of heavy and interrupted cuts is a massive, one-piece 45deg slant bed with a torque tube design and fine-grain Meehanite composition to withstand the shocks and vibrations caused by heavy and interrupted cuts. The bed further ensures a rigid base for maximum precision while maintaining minimal and constant distance from tool tip to guideway. The slant bed also helps direct chips and coolants away from the part and into the chip pan.
Widely spaced, wrap-around, rectangular guideways offer unsurpassed, long-term stability and accuracy. Each is induction hardened and precision ground. The mating surface is bonded with Turcite B fluroplastic resin for its excellent resistance to deformation, wear and friction, then hand scraped for perfect fit and center height.
The Puma’s 12-station turret features a large 15.8 in diameter Curvic coupling and 39,790 lb of clamping force that provides the rigidity needed for heavy stock removal, fine finishes, and longer tool life. A reliable, high torque, hydraulic index motor controls the turret rotation, deceleration and clamp. A 15 hp rotating tool motor generates 103.5 of low end torque, and a maximum of 3,000 rpm tool rotation. Tools are all Preci-Flex® ready for greater rigidity, and faster setups and tool replacements.
A tool monitoring system tracks the load on all axes and spindle motors, and alerts the operator to tool wear and breakage. Used with the Tool Life Management system, machines can be set to switch automatically to a redundant tool when wear reaches a predetermined amount.
Additional features found on the Puma 700LY include a programmable tailstock with a quill diameter of 6.3 in and stroke of 7.8 in; automatic lubrication to all guideways, ball screws and tailstock quill; a high capacity, multistage centrifugal coolant pump with a 158 gal reservoir; a waylube separation system; and an automatic tool setter. www.doosaninfracore.com/machinetools
