NAKAMURA TOME SC-100X2
The SC-100X2 is positioned as a highly productive machine that offers significant cycle time reductions (reportedly 41% faster than the SC-100). Its ability to perform superimposed and simultaneous machining makes it suitable for complex parts and a wide range of manufacturing sectors, including medical, construction, and general engineering. It's designed to be easy to operate with its intuitive software and automation features.
Key Features:
Twin-Turret Design: Utilizes two tools on either side of the upper turret for superimposed machining.
Superimposed Machining: Allows for simultaneous machining through overlapping control between the main and sub-spindles, significantly reducing cycle times.
Y-axis: Standard on the R-upper turret with a stroke of ±40mm (80mm total).
Milling Capability: Includes milling functions with dedicated milling tool stations.
FANUC CNC Control and Servo Drives: Ensures reliable and precise control.
User-Friendly Software: Features Nakamura-Tome's original unique software like "NT Manual Guide i" for fast and easy programming and setup, including drag-and-drop functionality for multi-path programs.
Oscillating Cutting: Helps prevent stringers or bird's nesting.
Digital Chuck Interlock: Reduces setup time by allowing arbitrary setting of chuck open/close positions.
Unloading Gripper with Built-in Parts Conveyor: Standard for automated bar work.
Thermal Compensation System using AI: Minimizes the impact of thermal changes on machining accuracy.
