Support Frame/Legs: Load Capacity 2000 kg

Q: What load capacity should Support Frame/Legs have for CNC work tables?

For CNC applications, Support Frame/Legs should have a minimum load capacity of 1500-3000 kg with a safety factor of 3-5, considering dynamic cutting forces, workpiece weight, and vibration damping requirements.

Q: How do I ensure proper leveling of Support Frame/Legs on uneven floors?

Use adjustable leveling feet with at least ±25 mm vertical adjustment and locking mechanisms. Perform initial leveling with precision spirit levels (0.02 mm/m accuracy) and verify with laser alignment systems during installation.

Q: What maintenance is required for Support Frame/Legs?

Quarterly inspections for structural integrity, bolt torque verification (re-torque to 80% of specified value), corrosion checks in aggressive environments, and lubrication of adjustment mechanisms every 6 months or 2000 operating hours.

Component Specifications

Definition

Support Frame/Legs constitute the foundational structural system of industrial work tables, engineered to withstand static and dynamic loads while maintaining dimensional stability. These components typically consist of vertical legs connected by horizontal and diagonal bracing members, forming a rigid framework that distributes operational forces to the floor. Critical design parameters include load capacity (typically 500-5000 kg), natural frequency to avoid resonance with machine vibrations, and deflection limits under maximum load conditions. Modern designs incorporate leveling mechanisms, vibration damping features, and modular connection systems for rapid assembly and reconfiguration.

Working Principle

The working principle involves transferring applied loads (equipment weight, operator forces, process forces) through a triangulated or box-section structure to the foundation, while maintaining geometric stability through rigid connections. Load paths are optimized to minimize stress concentrations, with bending moments resisted by the section modulus of structural members. Leveling systems use threaded feet or wedge mechanisms to compensate for floor irregularities, ensuring the work surface remains within specified flatness tolerances.

Materials

Structural steel (S235JR, S355JR), stainless steel (304, 316), aluminum alloys (6061-T6, 6082-T6), or composite materials. Surface treatments include powder coating (60-80 μm), hot-dip galvanizing (minimum 70 μm), or electrophoretic deposition for corrosion resistance.
