As China’s demand for road infrastructure maintenance continues to grow, projects such as the reconstruction and expansion of rural cement pavements and internal roads within industrial parks are becoming increasingly common. Consequently, the market is placing ever-higher demands on the efficiency, precision, and cost-effectiveness of cement pavement milling. Traditional milling cutters often encounter significant challenges—rapid wear, frequent replacement, and substantial overall cutting resistance—when processing high‑hardness cement concrete pavements of C30 grade or higher.

The Luoyang Jinlu cutting‑tooth R&D team has addressed the industry’s persistent challenges in road construction by developing corresponding mechanical models. Building on these models, they analyzed the factors influencing the cutting force of milling cutter teeth. In response to the demanding conditions posed by high‑grade concrete and complex milling operations, they have newly developed the G1‑1324 milling tooth. Extensive testing has demonstrated that this product significantly boosts milling efficiency, reduces pavement‑repair costs, and extends the service life of the cutting teeth by 20%–50%, earning unanimous praise from customers.

Key advantages of the Jinlu Milling and Planing Tooth G1-1324:

1. Ultra‑durable alloy cutting picks, crafted from Jinlu’s proprietary carbon‑tungsten alloy and manufactured using advanced vacuum sintering, achieve an optimal balance of hardness and toughness. Compared with mainstream market products, their wear resistance is improved by approximately 25%, effectively extending the service life of the picks, reducing downtime for replacement, and delivering tangible cost savings for customers.

2. Featuring a fluid‑mechanics‑based rock‑breaking structure, an innovative tooth‑tip geometry and a rear‑side backflow groove, this design significantly optimizes force distribution and chip evacuation during the cutting process. This unique configuration effectively reduces cutting resistance by approximately 20%, thereby not only increasing milling speed but also lowering both the machine’s energy consumption and the engine load.

3. Deep-hardened steel tooth bodies: The teeth are made from a special alloy steel and undergo deep carburizing, giving the entire component exceptionally high impact and bend resistance. This effectively prevents fracture and deformation under harsh operating conditions, ensuring construction safety.

4. Featuring exceptionally broad universal compatibility, this milling cutter tooth is compatible with numerous models of mainstream milling machines from both domestic and international brands (such as Wirtgen, SANY, etc.), offering customers the convenience of seamless upgrades.

Application Cases

In August 2026, product testing was conducted on the in‑park cement concrete pavement reconstruction and expansion project at the Guangzhou campus in Guangdong. Compared with products of the same configuration, our company’s G1‑1324 demonstrated a service life that is 30% longer than that of Brand Z.

The test conditions were on an in‑park cement‑concrete pavement, with a concrete grade of C30; certain areas contained reinforcing steel and other hard materials. The milling depth was 8 mm, resulting in significant cutter‑head wear, and a Wirtgen W205 milling machine was used.

Remnant Comparison:

Summary: In this test, in terms of wear resistance and handle‑breakage rate, Jinlu blade heads outperformed those of Brand Z.
