Product Specifications

Technical details and manufacturing context for Main Table

Definition
The Main Table is the central rotating component of a Rotary Table Assembly, serving as the primary workholding surface that securely positions and rotates workpieces for multi-axis machining, indexing, and precision positioning operations in industrial manufacturing equipment.
Working Principle
The Main Table rotates around its central axis, driven by a precision gear mechanism or direct drive system, allowing controlled angular positioning of workpieces for machining operations on multiple sides without repositioning.
Common Materials
Cast Iron, Steel Alloy
Technical Parameters
  • Diameter of the rotating table surface (mm) Standard Spec
Components / BOM
  • Table Surface
    Provides flat, precision-machined surface for workpiece mounting and clamping
    Material: Cast Iron
  • Mounting Holes
    Tapped holes or T-slots for securing workpieces and fixtures to the table
    Material: Steel
  • Rotation Bearing
    Supports the table and enables smooth, precise rotation with minimal friction
    Material: Bearing Steel
Engineering Reasoning
0-3000 N·m torque, 0-100 rpm rotational speed, -20°C to 80°C ambient temperature
Exceeding 3500 N·m torque causes permanent deformation, exceeding 120 rpm induces centrifugal forces > 1500 N, temperature > 100°C reduces yield strength below 250 MPa
Design Rationale: Plastic deformation due to exceeding yield strength (σ_y = 275 MPa for AISI 4140 steel), bearing seizure from thermal expansion exceeding 0.15 mm clearance, fatigue crack propagation at stress concentrations > 0.8σ_y
Risk Mitigation (FMEA)
Trigger Misalignment exceeding 0.05 mm/m during installation
Mode: Accelerated bearing wear causing 0.1 mm radial play within 500 operating hours
Strategy: Laser alignment system with 0.01 mm/m tolerance and real-time monitoring
Trigger Coolant contamination with >5% abrasive particles (size > 25 μm)
Mode: Surface pitting and scoring reducing flatness tolerance from 0.01 mm to 0.1 mm
Strategy: Multi-stage filtration system with 10 μm absolute rating and conductivity monitoring
