Outside Services
Finished Parts, Fully Handled.
Heat treat, anodizing, powder coating, plating, and precision grinding — coordinated through our network of trusted partner suppliers, managed end-to-end by C2Machine so your parts arrive finished and ready to install.
One PO. One Point of Contact.
Some jobs need more than machining. When your part calls for heat treatment, plating, or a specialized coating, we coordinate the outside processing through long-standing partner suppliers we trust — scheduling the work, moving the parts, and inspecting everything when it returns. You deal with C2Machine, not a supply chain of vendors.
Outside Services We Manage
Each service below is delivered through our qualified partner network, with C2 Machine handling coordination, traceability, and final verification.
Heat Treat
Stress relief, hardening, tempering, case hardening, and annealing through certified heat treat suppliers — bringing parts up to the hardness and strength your drawing calls for while keeping distortion under control.
- Stress relief and annealing
- Through-hardening and tempering
- Case hardening (carburizing, nitriding)
- Deep freeze
Anodizing
Type I, Type II, and Type III hard coat anodizing on aluminum parts for corrosion resistance, wear resistance, and a durable finish — with dye options available when your part needs a specific color or appearance.
- Type I and Type II anodize
- Type III hard coat anodize
- Corrosion and wear resistance
- Dye color options available
Powder Coating
Durable powder coat finishes in a wide range of colors and textures — a tough, uniform coating that resists chipping, scratching, and corrosion far better than wet paint, on parts of nearly any size.
- Wide color and texture selection
- Tough, chip-resistant finish
- Superior corrosion protection vs. paint
- Uniform coverage, inside and out
Hard Chrome
Industrial hard chrome plating for an extremely hard, low-friction, corrosion-resistant surface — ideal for wear surfaces, shafts, and tools, and useful for restoring worn dimensions to size.
- Exceptional surface hardness
- Low-friction wear surfaces
- Can restore worn dimensions
Black Oxide
Black oxide conversion coating for a matte black finish that resists light corrosion, reduces reflection, and gives parts a clean, uniform appearance — a common choice for tooling, fasteners, and components that shouldn't glare.
- Matte black, non-reflective finish
- Light corrosion protection
- Minimal dimensional change
OD Grinding
Cylindrical (outside diameter) grinding for parts that demand tight diameters, true roundness, and fine surface finishes — shafts, pins, rollers, and precision components finished to spec after turning or hardening.
- Tight diameter tolerances
- True roundness and finish
- Ideal for hardened shafts and pins
Passivation
Passivation for stainless steel parts — a chemical treatment that removes free iron from the surface and maximizes the natural corrosion resistance of the alloy, leaving parts clean, bright, and ready for service.
- Removes free iron from stainless surfaces
- Maximizes natural corrosion resistance
- Clean, bright, ready-to-use finish
How Outside Processing Works
We machine your part
Parts are produced in-house on our CNC equipment, to print, before any outside processing begins.
We route it to the right supplier
Your part goes to a qualified partner for heat treat, plating, coating, or grinding — we handle scheduling, shipping, and tracking.
We inspect on return
Finished parts are checked back in our shop — including dimensional verification on our 3D scanning system — before they ship to you.
Surface finishes and treatment results are performed by qualified partner suppliers; C2Machine manages the process and verifies the finished parts.
