Product Description
PDC Pick (PDC Point Attack Pick) is a high-end product specially designed by DQ DIAMOND for mining and foundation engineering. By replacing the tungsten carbide material of the cutting teeth with Polycrystalline Diamond composite material (PDC Cutter), this product is mainly used as the primary cutting teeth of large mining machines such as Coal Shearer Picks and rotary drilling rigs.
The product is manufactured by sintering the diamond layer and Tungsten Carbide Substrate (WC Matrix) at high temperature and high pressure. The diamond layer is compounded with countless microscopic diamond particles and bonding agents after strict ratio design, which gives the product ultra-high hardness, Wear Resistance (Abrasion Resistance), and unique ultra-fine Self-sharpening Ability; The Tungsten Carbide Substrate has good Impact Resistance (High Impact Toughness), and the two are perfectly matched to meet complex and harsh working conditions.
Product Advantage
- Wear Resistance: Made of premium selected materials, its Abrasion Resistance is 8 to 10 times stronger than ordinary steel or conventional hard alloy cutting heads.
- Safe and Explosion-proof: During the process of high-speed cutting and rock breaking, the tools remain completely Spark-free (No-sparking), reducing the risk of underground gas explosion and ensuring safe production.
- Strong and Impact-resistant: The Forged Body is made of high-quality 42CrMo Steel Body, and the special heat treatment quenching process makes full use of the material's properties to obtain optimum hardness and high toughness; The advanced Brazing (High-strength Brazing) technology ensures that the tip eliminates the risk of brazing joint failure.
- Cost-effective Mining: It achieves an Extended Tool Life (Long Service Life), effectively reducing downtime and pick replacement labor costs, thereby improving mining efficiency and ensuring a High Penetration Rate.
