USED 1990 TSUDAKOMA RNCV-300R
Overview
Description
Tsudakoma 12.5" CNC Rotary TableModel: RNCV-300R | Serial Number: 206278 | Year of Mfg: 1990OverviewThis Tsudakoma RNCV-300R is a precision 4th axis workholding solution designed for heavy-duty milling and high-accuracy indexing. Manufactured in 1990, this unit features the robust "R" (Rear Motor) configuration, allowing for a compact footprint on your machining center table without sacrificing X-axis travel.Known for its extreme rigidity, the RNCV-300R utilizes a hydraulic clamping system that provides massive holding torque, making it ideal for interrupted cuts and heavy material removal—applications where pneumatic tables often fail.Technical SpecificationsYear of Manufacture: 1990Table Diameter: 12.6" (320mm)Center Height (Horizontal): 8.27" (210mm)Center Hole Diameter: 4.13" (105mm) Through-HoleClamping System: Full HydraulicClamping Torque: 1,100 ft-lbs (1,500 N·m)Motor Mounting: Rear-Mount (Compact Design)Compatible Drive: Typically configured for Fanuc Servo Motors (verify motor model on-unit)Unit Weight: 405 lbsKey Features for S/N 206278Dual-Lead Worm Gearing: Proprietary Tsudakoma system that allows for precision backlash adjustment by moving the worm spindle axially. This ensures the table maintains its 15 arc-second accuracy even after decades of use.Oversize Cross Roller Bearings: Built with ultra-rigid bearings that support high radial and axial loads simultaneously, providing up to 400% more rigidity than standard angular contact bearings.Heavy-Duty Hydraulic Brake: The hydraulic lock ensures the table stays stationary during high-torque milling operations, preventing "brake slip" and protecting your workpiece finish.Horizontal or Vertical Mounting: Versatile base design allows for flat table mounting or upright mounting for shaft and trunnion work.
