Premium Laser-Cut 4140 Steel Toothed Profiles for Industrial Gears
As a dedicated manufacturer with over 20 years of expertise in metal fabrication, Anping County Boli Hardware Wiremesh Products Factory proudly presents our laser-cut special steel shapes designed for industrial machinery gears. Crafted from high-quality 4140 steel with a precise 20mm thickness and toothed profile, these components are engineered to meet the rigorous demands of heavy-duty gear applications. Our laser cutting technology ensures exceptional accuracy, minimal burr, and consistent repeatability, making every piece ready for further machining or direct assembly. With annual export values reaching US$5–10 million and serving markets across North America, South America, Europe, Asia, and beyond, we deliver reliability and precision at competitive costs.
Our 4140 steel toothed shapes are specifically designed for gear manufacturing in sectors such as automotive, agricultural machinery, mining equipment, and industrial automation. The combination of 4140 alloy steel (known for its excellent toughness, wear resistance, and fatigue strength) with laser cutting produces components that maintain tight tolerances and consistent geometry. Each shape is cut from 20mm thick plate, ensuring adequate load-bearing capacity for medium to large gears. The toothed profile can be customized to match your exact specifications – including module, pressure angle, and number of teeth – allowing for seamless integration into your existing gear systems.
Key Product Features & Technical Specifications
- Material: 4140 chromium-molybdenum alloy steel, heat-treatable for enhanced hardness (optional).
- Thickness: 20mm (nominal), with ±0.1mm tolerance achievable on laser-cut edges.
- Profile: Toothed (involute or custom profiles), cut directly from CAD data without tooling costs.
- Process: Fiber laser cutting – clean, precise, with minimal heat-affected zone (HAZ).
- Surface Finish: As-cut (deburred) or optional blasting, phosphating, or oiling.
- Customization: Any tooth count, pitch, or shape – quick turnaround on prototypes.

Advantages of Choosing Our Laser-Cut Gear Shapes
- No Tooling Costs: Laser cutting eliminates the need for expensive molds or dies, making it cost-effective for small to medium batches.
- Fast Prototyping: From CAD to cut part in 24–48 hours, enabling rapid iteration and development.
- Consistent Quality: Computer-controlled process ensures every piece is identical, reducing assembly issues.
- Material Efficiency: Nesting software optimizes plate usage, minimizing waste and lowering your material cost.
- Versatile Customization: Change tooth profile, internal bore, or external shape without affecting lead time.
- Heat Treatment Ready: 4140 steel can be induction hardened, carburized, or nitrided after cutting to enhance surface durability.
Our laser-cut steel shapes are supplied with a clean, deburred edge, ready for subsequent operations such as drilling, tapping, or heat treatment. For customers who require finished gears, we can also provide additional machining services (e.g., keyway cutting, bore finishing) through our trusted partner network. The 20mm thickness combined with 4140 material offers an excellent balance of strength and machinability, making these shapes ideal for medium-duty gear applications where reliability is critical.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity for laser-cut gear shapes?
A: There is no strict MOQ – we accept small prototype orders (e.g., 1-10 pieces) as well as large production runs. Pricing is adjusted based on quantity. -
Q: Can you cut other thicknesses besides 20mm?
A: Yes, we can cut 4140 steel from 3mm to 50mm thickness. The 20mm option is a standard offering; please specify your required thickness. -
Q: Do you provide heat treatment after cutting?
A: We can arrange heat treatment (e.g., annealing, quenching, tempering) through our qualified partners. However, the standard product is as-cut. Heat treatment is available upon request. -
Q: How do I ensure the toothed profile matches my gear design?
A: Send us your CAD file (DXF, DWG, STEP) or a detailed drawing with tooth parameters. We will verify the geometry before production and can suggest minor adjustments for optimal laser cutting. -
Q: What is the typical lead time?
A: For prototypes, 2-3 working days after drawing approval. For production orders (1000+ pieces), lead time is 7-15 working days, depending on complexity and current workload. -
Q: Do you offer material certificates?
A: Yes, we can provide mill test certificates for 4140 steel plates upon request, confirming chemical composition and mechanical properties. -
Q: Can you drill holes or add keyways to the gear shapes?
A: Yes, we can perform secondary operations such as drilling, tapping, and keyway cutting. Please specify your requirements for a complete quote.
