Technical details and manufacturing context for Cutting Drum
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Drum Diameter | 500–1200 mm | Determines cutting depth and machine class |
| Cutting Width | 350–2200 mm | Matches road width and production rate |
| Tool Holder Spacing | 15–30 mm | Affects cutting pattern and surface texture |
| Number of Tool Holders | 40–180 | Influences tool wear and cutting efficiency |
| Maximum Rotational Speed | 80–120 rpm | Higher speed increases production but reduces torque |
| Cutting Depth | 0–300 mm | Limited by drum diameter and machine power |
| Drum Width Tolerance | ±1.5 mm | Ensures uniform cutting across widthISO 2768-m |
| Hardness (Surface) | HRC 50–60 | Wear resistance of drum body |
| Material Grade | Q345B–Q460C | Structural steel for strength and weldabilityGB/T 1591 |
| Weight | 500–5000 kg | Affects machine stability and transport |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The drum diameter typically ranges from 500 to 1200 mm, which determines the cutting depth and machine class. However, the exact diameter must be confirmed with the manufacturer for a specific model.
The cutting drum is typically made of high-strength alloy steel, with a surface hardness of HRC 50–60. The structural steel grade is often Q345B–Q460C per GB/T 1591, but this should be verified with the supplier.
The drum rotates at speeds of 80–120 rpm while the machine advances. The cutting tools on the drum shear and fracture the pavement material. The depth of cut and forward speed are coordinated to achieve the desired removal rate and surface finish.
Key parameters include drum diameter, cutting width, tool holder spacing, number of tool holders, maximum rotational speed, cutting depth, width tolerance, surface hardness, material grade, and weight. Always confirm these values with the legal manufacturer or supplier for your specific application.
