Chassis & Frame Industry Laser Solution

Industry Background

Chassis and frame assemblies for excavators, loaders, rollers, mining trucks and forklifts are mainly manufactured from Q235 / Q355 medium‑heavy carbon steel plates. Traditional flame or plasma cutting brings large heat‑affected zones and plate warping deformation, which directly influences later assembly accuracy. A large quantity of scattered mounting holes need separate secondary drilling operations, which causes accumulated position tolerance. Large‑size chassis components require machine tools with rigid heavy‑duty bed and stable long‑time continuous‑running performance.

Sub Application Scenarios

• ✅ Main Chassis Base Plate: Heavy‑plate blanking and distributed mounting hole cutting
• ✅ Chassis Side Protection Plate: Contour cutting, notch and positioning hole machining
• ✅ Frame Connecting Plate: Medium‑thick plate special‑shaped outline & hole processing
• ✅ Reinforcement Stiffener Plate: Multi‑hole precision cutting for chassis strengthening structure
• ✅ Auxiliary Process: Laser welding for chassis frame assembly, oxide cleaning before painting

Industry Pain Points

• Flame / plasma cutting creates serious thermal deformation, resulting in chassis flatness out‑of‑tolerance.
• Scattered mounting holes need independent drilling procedures, increasing labor cost and production cycles.
• Frequent drawing revisions for different machinery models bring high custom fixture investment.
• Oversized chassis workpieces put forward high requirements for machine‑bed rigidity and load capacity.
• Mixed‑thickness chassis components, hard to balance processing efficiency and finished‑part quality.
• Batch production requires stable long‑time‑running equipment performance for heavy‑plate cutting.

Our Targeted Laser Solution

• High‑power heavy‑duty laser cutter completes chassis blanking, contour and all mounting holes in one‑step procedure, cancels separate secondary‑drilling work.
• Controlled low‑heat‑input cutting minimizes thick‑plate warping deformation and guarantees chassis flatness requirement.
• Heavy‑duty stress‑relieved machine‑bed adapts large‑format oversized chassis plates.
• No custom fixture required; import revised CAD drawings directly for new‑model chassis prototypes.
• Oxygen / nitrogen assist gas optional for different steel thickness to balance cutting quality and running‑cost.
• Stable continuous‑production capacity, fits small‑batch prototype trial and large‑volume chassis manufacturing orders.
