Secondary Manufacturing Operations
What Are Secondary Operations?
Secondary manufacturing operations are the processes carried out after the initial cutting stage to refine, finish, and prepare components for their final use.
While laser cutting produces accurate profiles, additional processes such as tapping, countersinking, deburring, and surface finishing are often required to meet functional and assembly requirements.
These operations ensure parts are not only dimensionally accurate, but also safe to handle, properly prepared for fasteners, and ready for coating, welding, or installation.
Simplify Your Supply Chain
Managing multiple suppliers for secondary operations can quickly become time consuming and difficult to control. Delays, miscommunication and inconsistent quality are common when parts are passed between different providers.
By working with SSC Laser, you deal with a single, reliable partner who manages the entire process for you. From machining and finishing to coating and assembly preparation, everything is coordinated through one point of contact. This reduces admin, improves communication, and ensures every stage meets the same high standard.
Machining Services
Machining services are processes used to refine and enhance laser cut parts to meet exact functional requirements.
While laser cutting produces accurate profiles, additional machining is often required to create threads, improve hole accuracy, and ensure components are ready for assembly. These processes allow parts to meet tight tolerances, accept fixings, and perform reliably in their final application.
Tapping
Thread cutting to create clean, reliable fixing points for bolts and fasteners.
Countersinking
Creates a conical recess so screws sit flush with the surface for a neat, professional finish.
Counterboring
Machines flat bottomed holes to allow fasteners to sit below the surface for a clean assembly.
Milling
Removes material to form slots, pockets and complex features.
Reaming
Refines holes to exact sizes with a smooth finish for tight tolerance applications.
Deburring
Removes sharp edges and burrs to improve safety, handling and overall part quality.
Surface Finishing Services
Surface finishing plays a critical role in protecting metal components, improving durability, and enhancing overall appearance. After laser cutting and machining, applying the right finish ensures parts are ready for their working environment, whether that’s corrosion resistance, wear protection, or aesthetics.
Bright Zinc Plating
Bright zinc plating is a cost effective finishing process that provides a thin protective coating to steel components.
- Helps prevent corrosion in indoor and light outdoor environments
- Provides a clean, bright metallic appearance
- Ideal for fasteners, brackets, and general purpose parts
- Maintains dimensional accuracy due to its thin coating
This is a popular choice where protection and appearance are required without significantly altering part tolerances.
Galvanising
Galvanising is a heavy duty coating process where steel components are coated in a layer of zinc to provide long term corrosion protection.
- Excellent resistance to rust and weathering
- Ideal for outdoor, structural, and harsh environments
- Long lasting protection with minimal maintenance
- Suitable for larger fabricated parts and assemblies
Galvanising is typically used where durability and lifespan are more important than cosmetic finish.
Powder Coating
Powder coating is a durable finishing process that applies a protective and decorative layer to metal surfaces.
- Available in a wide range of colours and finishes
- Provides strong resistance to wear, impact, and corrosion
- Creates a consistent, high quality surface finish
- Suitable for both functional and aesthetic applications
This is often chosen where appearance is just as important as protection, such as visible components or branded products.
Anodising
Anodising is an electrochemical process used primarily on aluminium to enhance its natural properties.
- Increases corrosion resistance and surface hardness
- Produces a clean, uniform finish that won’t peel or flake
- Available in natural or coloured finishes
- Maintains a lightweight, high quality appearance
Anodising is ideal for precision aluminium components where durability, finish, and performance are all important.
Welding Services
Welding is a fabrication process that uses heat to fuse metal components into a single solid structure. It's a crucial step in turning laser cut parts into fully formed assemblies, ensuring strength, stability, and long term performance.
When laser cutting and welding work together, components are produced with the accuracy needed for clean, precise joins. This reduces fitting issues, improves efficiency, and helps to maintain consistent quality throughout production.
With SSC you benefit from a streamlined workflow.
MIG Welding
Reliable and cost effective welding for high volume production. Ideal for structural components and general fabrication where strength, speed, and consistency are key.
TIG Welding
Welding for high spec components where finish and detail matter. Perfect for clean, accurate welds on stainless steel, aluminium, and visible parts.
Fabrication Assembly
Transforming laser cut parts into complete, ready to use assemblies. Simple brackets to complex fabrications, we deliver fully formed components ready for installation.
MIG vs TIG Welding
| Feature | MIG Welding | TIG Welding |
|---|---|---|
| Accuracy | Less precise but faster for general fabrication | Precise with full control over the weld |
| Finish Quality | Good finish, may require post-processing | High quality finish with minimal clean-up |
| Best Materials | Mild steel and thicker materials | Stainless steel, aluminium, and thinner materials |
| Speed | Fast and efficient for production work | Slower, focused on accuracy and detail |
| Skill Level | Easier to learn and operate | Requires higher skill and experience |
| Typical Use Cases | Structural parts, general fabrication, batch production | Precision parts, visible welds, high spec components |
| Cost Efficiency | More cost effective for larger volumes | Higher cost due to time and precision |
Metal Flattening Services
Our metal flattening services form part of our wider secondary operations offering, ensuring laser cut parts are flat, stable, and ready for the next stage of production.
Not all parts require flattening. In some cases, components will remain sufficiently flat after cutting. However, depending on the material, thickness, and profile complexity, laser cutting can introduce internal stresses that cause parts to bow, twist, or distort. Where this occurs, flattening becomes an important step to restore the material to a consistent, usable condition.
Flattened components are better suited for downstream processes such as bending, welding, machining, and surface finishing, helping maintain accuracy and overall part quality.
When Is Flattening Needed?
Thin sheet metal
Lighter gauge materials are more prone to movement and distortion during the cutting process.
Large or wide parts
Increased surface area can lead to bowing or unevenness across the component.
Complex profiles
Parts with multiple internal features, tight nesting, or intricate geometries can build up stress during profiling.
Tight tolerance requirements
When tolerances are critical, even minor distortion can affect fit and function.
Secondary Operations FAQs
Secondary operations are additional processes carried out after initial manufacturing, such as laser cutting. These can include flattening, bending, welding, machining, and surface finishing, all of which prepare parts for final use or assembly.
Yes, multiple processes can be combined as part of a single project. This reduces the need to manage multiple suppliers and helps ensure consistency across every stage of production.
Not always. Some parts can be used directly after cutting. However, operations like flattening, bending, or finishing may be required depending on the material, design complexity, and end use.
Using a single supplier helps streamline your workflow, reduce lead times, and maintain consistent quality. It also simplifies communication and project management.
