Component Specifications

Definition
The Ball Screw Nut Bracket is a critical mounting component in CNC machine tools that rigidly fixes the ball screw nut to the carriage assembly on the Y-axis. It provides precise alignment and support to convert the rotary motion of the ball screw into linear movement of the carriage, maintaining positional accuracy and minimizing deflection under load.
Working Principle
The bracket mechanically couples the ball screw nut to the carriage structure. As the ball screw rotates, the nut moves linearly along the screw threads. The bracket transfers this motion to the carriage while preventing rotation of the nut, ensuring pure translational movement along the Y-axis guideways.
Materials
Typically manufactured from high-strength aluminum alloys (e.g., 6061-T6, 7075-T6) or structural steel (e.g., AISI 1045, S45C) with precision machining. May include hardened steel inserts at mounting points.
Technical Parameters
  • Stiffness >100 N/μm
  • Surface Finish Ra 1.6 μm or better
  • Weight Capacity 50-500 kg depending on design
  • Mounting Hole Pattern ISO metric or custom
  • Operating Temperature -20°C to 80°C
Standards
ISO 3408, DIN 69051
