New CNC Heavy Duty Turning Centre Available

New CNC Heavy Duty Turning Centre Available CNC heavy duty VT-40/VT-50 Turning Centres available from Standaco Machinery have big spindle bores of 131, 185, 235, 360 and 435mm that allow heavy cutting on big parts. The rigid Meehanite cast-iron bed construction provides ideal machine tool accuracy and reliability, as the heat treatment provides release of residual stress. The 45¡ã slant-bed design with integrated ribbing tube structure gives the machine exceptional stability in heavy-cutting operation and optimal chip removal. The cutting forces are increased, resulting in a high degree of precision. Z-axis travels are available in 1, 2, 3 and 4 metres. Both X and Z Axes are supported by oversized, hardened ground box-type ways with rapid rates of 15m/min on the X axis and 16m/min on Z axis. The headstock has thermal deformation prevention design for higher accuracy. The 50HP spindle motor provides the torque to turn a range of materials at a variety of feeds and speeds. Made of SCM21 alloy steel, the spindle provides good surface finishing and metal removal. The high-accuracy P4 grade angular contact thrust spindle bearings from NSK, SKF or FAG ensures precision turning during long-term operations. The 12 station tool turret with 1 second station index time is designed to allow 32mm shank height square tooling and Ø60mm shank diameter for boring tool with minimum tool interference. The curvic coupler, hydraulic actuator and position encoder are to enhance reliability and durability.The powerful, robust ball screws generate slide-way movement in both X and Z axes. Using only the fine materials, both axes are driven by an ultra-precise ball screw that is pre-loaded and double-anchored for optimum drive conditions. The hydraulic tailstock has a 150mm diameter quill, a No. 6 Morse Taper and a generous stroke of 150mm. A programmable tow-along tailstock is available as an option. The tailstock is box type way system, seated on the same 45¡ã angle surface as the X-Axis turret movement. The hydraulic motor and amp; rack / pinion assembly with movable stopping limit switches is an alternative option to positioning the tailstock to increase efficiency. Slide-ways and ball screws are lubricated by a centralised volumetric lubrication system. The automatic supply of slide-way lubrication is constantly monitored to ensure the amount of lubricant in circulation. The sophisticated lubrication monitoring system ensures complete lubrication by detecting any oil leakage or oil pressure reduction to avoid any potential downtime problem. The optional tool pre-setting system reduces the time for set-up and tool changing, as well as insuring the accurate measurement of tool offsets; it also allows various checkpoints throughout the program to obtain optimal part accuracy and finish. These tool offsets are quickly and accurately measured by the tool pre-setter probe system.
