Workpiece Tray

Application – Agricultural Machinery Manufacturing & Workshop Handling

This CNC metal spun workpiece tray is designed for agricultural machinery production, assembly lines, and material handling systems, providing a high-strength, load-bearing solution for tractors, harvesters, and seeding equipment manufacturing environments.

Material Specification – Q235B Carbon Steel

Manufactured from Q235B carbon structural steel (GB/T 700-2006), ensuring stable mechanical performance for industrial use.

• Yield strength: ≥ 235 MPa
• Tensile strength: 370–500 MPa
• Elongation: ≥ 26%
• Density: 7.85 g/cm³

Provides an optimal balance of strength, toughness, and formability for repeated handling and load cycles.

Product Dimensions & Tolerances

• Size: Ø572 mm × 35 mm
• Thickness: 4.0 mm (±0.15 mm)
• Roundness: ≤ 0.3 mm
• Flatness: ≤ 0.2 mm/m
• Standard: GB/T 1804-2000 (Grade m)

Ensures high dimensional consistency for automated and manual assembly workflows.

Manufacturing Process – CNC Metal Spinning Forming

Produced using CNC metal spinning technology (CNC1250 equipment platform) for high-efficiency precision forming.

Core Process Parameters:

• Spindle speed: 500–900 r/min
• Feed rate: 4–8 mm/s
• Controlled deformation: 3.8–4.2 mm

Process Flow:
Degreasing → leveling → CNC spinning → deburring → compressed air cleaning → final inspection

Delivers uniform wall thickness, high concentricity, and repeatable batch consistency.

Surface Condition – Industrial-Grade Finish

• Bare steel (no coating) for flexibility in downstream processing
• Surface roughness: Ra ≤ 1.6 μm
• Mechanical deburring for safe handling
• Ready for coating, welding, or assembly integration

Precision & Quality Control System

Manufactured under ISO 9001:2015 quality management system.

Incoming Material Inspection

• Spectral chemical analysis (C ≤ 0.22%, Mn ≤ 1.4%)
• Ultrasonic testing for internal defect detection
• Mechanical property verification

In-Process Control

• CMM dimensional inspection
• Wall thickness control (±0.01 mm monitoring)
• Full-circle geometry verification
• Edge radius ≥ 1.5 mm (no sharp edges)

Final Inspection

• GB/T 2828.1-2012 (AQL 2.5 sampling standard)
• Dimensional, surface, and load performance checks
• Full traceability with inspection report

Production Capacity & Delivery

• Daily output: 60 pcs
• Monthly capacity: 1,800 pcs
• Standard lead time: 4–7 days
• Bulk orders (100+): 7–10 days
• Rush production: 2–4 days (subject to capacity)

Packaging: anti-rust protection + foam + carton + wooden pallet
Logistics: domestic 2–5 day delivery, on-site supply for OEM manufacturers

Custom Manufacturing Capability

• Diameter range: Ø300–1000 mm
• Height range: 20–80 mm
• Material options: Q235B, Q355B, carbon steel variants
• Custom OEM design based on machine interface and load requirements

Application Scenarios

Widely used as industrial workpiece handling and support trays in:

• Agricultural machinery (tractors, harvesters, seeders)
• Construction machinery component logistics
• Mining equipment parts handling
• Warehouse and assembly line transport trays

Supports safe component transfer, temporary storage, and production line efficiency optimization.

Engineering Value

Compared with welded or fabricated trays, CNC spun structure provides:

• Higher structural integrity under repeated loading
• Reduced deformation risk during long-term use
• Improved batch consistency for OEM production
• Lower maintenance and replacement frequency
