How Is the “Skeleton” of a Laser Cutting Machine Built? — Inside the In-House Manufacturing Process of Derateck Laser Machine Bed

In a laser cutting machine, the machine bed is like its “skeleton.” It not only supports the entire weight of the machine, but also directly determines stability, precision retention, and service life. At Derateck, we have always adhered to one principle: core components must be made in-house. Today, let’s step into the Derateck workshop and uncover the full manufacturing process behind our laser cutting machine beds.

 

Step 1: Laser Cutting — Precision Controlled at the Source

All steel plate welding components for Derateck laser machine beds are cut using laser cutting machines. Compared with traditional cutting methods, laser cutting produces burr-free edges, smooth and clean cut surfaces, a smaller heat-affected zone, and significantly reduced thermal deformation. High-precision cutting dimensions provide a solid foundation for subsequent assembly and welding, ensuring better control of overall bed dimensions and guaranteeing accuracy from the very beginning.

 

Step 2: Mortise-and-Tenon Welded Structure — Building a Solid Foundation

In structural design, Derateck laser machine beds adopt a mortise-and-tenon welded structure. This design distributes stress more evenly, delivers high overall rigidity, and effectively resists structural deformation, laying a strong foundation for long-term stable operation.

During welding, CO₂ gas-shielded welding is used to ensure a stable process, well-formed weld seams, minimal spatter, and fewer internal defects. After welding, all seams are carefully ground to completely remove slag and burrs, resulting in a smoother surface and preparing the bed for subsequent processes.

 

Step 3: Annealing + Sandblasting — Dual Assurance of Stability and Coating Adhesion

To thoroughly eliminate internal stress generated during welding, Derateck performs full-body annealing on the machine bed. By precisely controlling temperature and time, internal stress is fully released, ensuring the bed remains dimensionally stable and accurate over long-term use.

After annealing, the bed undergoes sandblasting. This process not only removes surface residues but also increases surface roughness, significantly improving paint adhesion and providing an ideal base for subsequent coating.

 

 

 

Step 4: CNC Gantry Milling — Precision Firmly Secured

Ultimately, machine bed accuracy is achieved through precision machining. Derateck follows a proven process route: rough machining → natural aging → finish machining.

Rough machining: Large feed rates and cutting depths are used to quickly remove excess material.

Natural aging: Residual stresses are further released over time, preventing deformation during later machining and use.

Finish machining: High-precision CNC gantry machining centers are used to precisely machine key mounting surfaces such as guide rails and racks, ensuring high-quality installation references.

 

 

Step 5: Dual-Layer Coating — More Than Appearance, It’s Protection

For surface treatment, Derateck applies a primer + topcoat painting process. The primer offers strong adhesion and excellent sealing, effectively protecting the substrate and improving surface flatness. The topcoat, as the outermost layer, combines aesthetic appeal with protective performance, making the machine bed more durable and visually refined.

Derateck is equipped with dedicated spray booths for large structural components, with strict control over temperature, humidity, lighting, and air cleanliness—ensuring consistent and stable coating quality for every machine bed.

 

In-House Manufacturing Defines Derateck Quality

When core technologies stay in our own hands, quality is truly under control. Rigorous control at every process and meticulous attention to every detail are all aimed at delivering laser cutting equipment that is more stable, more precise, and more durable. Looking ahead, Derateck will continue to deepen its commitment to independent R&D and manufacturing, providing global customers with more competitive laser processing solutions.
