Xiamen Goldcattle, with 26 years in industrial metal fabrication, specializes in custom machinery equipment parts—covering gearboxes, bearing housings, hydraulic manifolds, conveyor components, and drive shafts (steel/stainless/aluminum materials). Crafted via advanced 5-axis CNC machining and precision casting, we deliver ±0.01mm tolerance parts, backed by ISO 9001 and ISO 13485. From prototypes to 50,000+ units/month, our components ensure high load capacity, wear resistance, and perfect fit for 60+ global industrial manufacturers.
Core Processing Technologies: Engineering for Machinery Durability
Machinery equipment parts operate under extreme conditions—high torque, continuous vibration, and exposure to dust/oil. Goldcattle’s technologies ensure parts withstand heavy loads and extend equipment lifespan.
1. High-Precision CNC Machining
- 5-axis CNC milling: Shapes complex components (e.g., hydraulic manifolds with multi-axis ports) with ±0.005mm accuracy, ensuring fluid flow efficiency (pressure loss ≤5%). A 6-inch hydraulic manifold for industrial presses achieved 0.01mm port alignment, eliminating leaks.
- CNC turning with live tooling: Produces shafts, bushings, and collars with tight concentricity (≤0.002mm), critical for high-speed rotating parts. A 30mm drive shaft for conveyor systems maintained balance at 3,000 RPM, reducing vibration by 60%.
- Wire EDM cutting: Creates precision gears and keyways (tolerance ±0.003mm) in hardened steel, ensuring mesh accuracy (backlash ≤0.05mm) for gearboxes.
2. Heat Treatment & Material Strengthening
- Carburizing & quenching: Hardens gear teeth and bearing surfaces to 58-62 HRC, with a ductile core (30-35 HRC) for impact resistance. A 40-tooth industrial gear treated this way endured 10 million cycles without wear.
- Nitriding: Enhances surface hardness of hydraulic components (e.g., valve spools) to 1,000HV, reducing friction and extending service life by 3x in oil-rich environments.
- Stress relief annealing: Eliminates internal stresses in large parts (e.g., 1m-long conveyor frames), preventing warpage under continuous load (≤0.02mm/m deformation).
3. Surface Coating & Corrosion Resistance
- Hard chrome plating: Applied to hydraulic rods and piston shafts, providing 0.05-0.1mm thick wear layers (65 HRC) and corrosion resistance (500 hours salt spray).
- Powder coating: For structural parts (e.g., machine frames), offers 80-120μm thick layers with UV resistance, ideal for outdoor agricultural machinery.
- PTFE coating: Reduces friction on sliding components (e.g., linear guide rails) by 40%, ensuring smooth operation in food processing equipment (compliant with FDA 21 CFR 177.1550).
4. Quality Testing for Industrial Reliability
- Dimensional inspection: CMMs verify critical features—bearing seat tolerance (H7), gear pitch (±0.01mm), and shaft straightness (≤0.05mm/m).
- Mechanical testing: Tensile strength (≥600MPa for structural parts), impact resistance (-40℃, ≥27J), and fatigue testing (10 million cycles at 80% load) ensure durability.
- Pressure testing: Hydraulic manifolds and valves undergo 3x working pressure tests (e.g., 300bar for industrial hydraulics) with zero leakage.

Machinery Parts Machining Technologies
- Multi-axis CNC machining: 5-axis mills produce complex hydraulic manifolds with intersecting ports (±0.01mm position tolerance), eliminating assembly leaks in industrial presses.
- Precision grinding: Cylindrical grinding achieves Ra 0.02μm surface finish on bearing seats, reducing friction and extending bearing life by 50%.
- Automated production cells: Robotic loading/unloading and in-line CMM inspection ensure 99.9% consistency for high-volume parts (e.g., 10,000 conveyor rollers/month).
Custom Machinery Parts Manufacturing Process
- Design & DFM: Engineers analyze client CAD files (STEP/IGS) to optimize for load distribution—e.g., adding fillets to gear teeth to prevent fatigue failure.
- Material selection: Choose alloy steel for high-torque parts (e.g., 4140 for drive shafts) or 316 stainless for corrosive environments (e.g., chemical processing equipment).
- CNC machining: Milling/turning creates base features; wire EDM adds precision details (keyways, gear teeth); grinding refines bearing surfaces.
- Heat treatment: Carburizing/quenching enhances surface hardness, followed by stress relief to prevent warping under load.
- Surface coating: Chrome plating or powder coating applied per environment (e.g., food-grade coatings for 304 parts).
- Quality validation: CMM inspection, pressure testing, and fatigue trials ensure compliance with ISO 9001 and client specs.
Custom Machinery Parts Application Fields
- Industrial machinery: Gearboxes, hydraulic manifolds, and bearing housings for injection molding machines, presses, and robotics (alloy steel, 4140).
- Agricultural equipment: wear-resistant steel plow components, stainless steel irrigation system parts (resistant to fertilizer corrosion).
- Food processing: 304 stainless steel conveyor belts, hydraulic cylinders with FDA-compliant coatings (easy to sanitize).
- Construction machinery: Ductile iron bearing housings, high-strength steel bucket teeth (withstand 500+ hours of rock impact).
- Medical equipment: Aluminum alloy precision manifolds for diagnostic machines (lightweight, corrosion-resistant).
