Structural Design Details
(1) Hierarchical Platform Structure
• Upper Working Surface: 25mm thick quenched steel plate, covered with standard positioning holes, surface roughness Ra0.8μm
• Middle Reinforcement Layer: Honeycomb - shaped reinforcing rib structure, balancing lightweight and torsional stiffness
• Bottom Base: Adjustable foot design (±15mm height adjustment), adaptable to uneven ground
(2) 3D Positioning System
• X/Y - axis Positioning:
Achieved through D28 hole system + positioning pins, with repeat positioning accuracy of ±0.01mm
Digital display scale system (resolution 0.001mm) is optional
• Z - axis Adjustment:
Integrated screw - lift mechanism (stroke 50mm, fine - tuning accuracy 0.02mm)
Supports quick - detachable height shim sets
(3) Modular Expansion Interfaces
• M12 threaded mounting holes (spacing 100mm) are reserved on the four - side frame
• Side T - slots (width 22mm) are used for installing auxiliary brackets
• The central area can be replaced with a vacuum adsorption module (optional)
| Aspect |
Cast Iron |
Q355 (Structural Steel) |
| Material Category |

Replaces the old grade Q345. |
| Key Composition |
High carbon (2-4%), high silicon (1-3%), low manganese (0.1-1%). |
Low carbon (≤0.24%), low silicon (≤0.55%), manganese (1.0-1.6%), with microalloys (Nb, V, Ti). |
| Mechanical Properties |
- Tensile Strength: 120-400 MPa (low) |
- Tensile Strength: ≥355 MPa (actual: 470-630 MPa) |
| - Brittle, low toughness |
- High toughness, impact resistance |
| - High hardness (HB 150-300) |
- Moderate hardness (HB 130-180) |
| - Poor weldability. |
- Excellent weldability. |
| Manufacturing Process |
Casting (molten metal poured into molds). Ideal for complex shapes. |
Hot/cold rolling, forging. Easy to cut, weld, and machine. |
| Applications |
Engine blocks, machine tool bases, pipes, cookware (e.g., cast iron pans). |
Structural frameworks (buildings, bridges), ships, pressure vessels, machinery. |
| Advantages |
Cost-effective, wear-resistant, good vibration damping. |
