Steel Plate Cutting for Agricultural Machinery: Typical Parts and Specifications
Agricultural machinery is high-volume, moderate-precision work. Most parts run 6–30mm in Q235 or Q345. The majority fall well within laser cutting range. Seasonal ordering patterns mean planning ahead is essential.
Common Steel Grades in Agricultural Machinery
| Grade | Application | Typical Thickness |
|---|---|---|
| Q235 / A36 / S235 | Housings, covers, light structural brackets | 3–12mm |
| Q345 / A572 / S355 | Main frame, chassis, load-bearing brackets | 8–25mm |
| NM360 / NM400 | Plow blades, cutting edges, wear strips | 8–20mm |
| Q420 / S420 | High-stress components on heavy equipment | 10–30mm |
Typical Parts and Cutting Specifications
Chassis and frame plates: Q345, 12–25mm, laser cut to ±0.1 ~ ±0.3 mm. Mounting holes, bolt patterns, and interface profiles require consistent accuracy across large production batches.
Plow shares and ground-contact wear parts: NM360 or NM400, 8–16mm, shaped profiles with cutting edges. These are typically laser cut for profile accuracy. The wear resistance comes from the material grade, not from post-processing — get the grade right at ordering.
Laser Cutting for Agricultural Parts
Many agricultural machinery plate parts fall within the laser cutting range (0.5–55mm). Laser cutting handles the profile accuracy required for hitch interfaces, mounting patterns, and shaped components.
Maximum laser panel size at YUNCUT is 3500mm × 26000mm. This handles most agricultural frame and chassis components without joining. Very long beam sections or hitch arms that exceed this size move to flame cutting.
Batch Characteristics and Seasonal Planning
Agricultural equipment procurement tends to be seasonal — high demand before planting seasons, lower in off-season. This creates predictable high-volume windows. Suppliers with capacity constraints may deprioritise new buyers during these windows.
Plan orders well ahead of your required delivery date to account for production plus ocean freight. For repeat annual programs, confirm quantities and drawings in the preceding quarter to lock capacity.
Surface Treatment for Agricultural Parts
Shot blasting (Sa2.5) is available for parts requiring paint or coating preparation. Maximum part size for shot blasting is 2700mm × 8000mm. For agricultural parts going into powder coat or epoxy paint lines, shot blasting at the cutting stage can remove the need for a separate surface prep step at the finishing stage.
