ZZ HARDMETAL -DRILL BRANCH is a member of Chinese Drill Steel & Drill Tools Association.We are doing continuous technical communication with the laboratories focusing on mining, drilling and tunneling of Chinese famous universities, such as the Drilling Research Laboratory of China University of Geosciences and the Institute of Forming Technology & equipment of Shanghai Jiao Tong University. In the meantime, we closely cooperate with the professional research institutions, Changsha Institute of Mining Research and China Coal Technology & engineering group Shanghai Research Institute.
We integrated the top manufactures of Chinese Drill Steel & Drill Tools Association and keep good business relationship with international famous enterprises.
After analyzing the domestic and international advanced drilling theory, we develop new manufacturing technique, aiming to purchase suitable raw material, produce good tungsten carbide in right grade, develop impeccable manufacturing process, and adopt appropriate heat treatment to produce advanced, stable, reliable and outstanding products.
We own the specialized export company - Zhuzhou ZZ Import and Export Co., Ltd. Our products are exported to USA, Europe, etc. and got trust from our customers. Along with our company growth, we hope to build business with more company abroad.
Competitive products and Manufacturing process:
Cutting tooth and Engineering tool: Super-coarse-grain-size tungsten carbide, suitable welding technique and perfect heat treatment after welding.
Tapered chisel bits and cross Bit: reasonable selection of steel and tungsten carbide which perfectly bonded by high-frequency welding.
Tapered button bits: Cold forging process and excellent heat treatment exactly combined with the cold inlaying technique.
Thread button bits: Correct selection of material and hot mounting process.
DTH bits: Perfect combination of material selection, heat treatment, and cold inlaying process.
DTH Hammer: Perfect combination of accurate gas distribution, impeccable processing process, selection of material and heat treatment.
Roller bits: Modern high-tech products; the design includes CAM three-dimensional simulation, material simulation and structure simulation. The quality is guaranteed by the strict demanding of working condition simulation, aerodynamic force, fluid design and the advantage manufacturing process of material nondestructive inspection, 5000 ton hydraulic forging, ultrasonic flaw detection, center flexible machining, partial surface hardening treatment, surface hardening treatment of bearing, partial cryogenic processing treatment, heat treatment and high-end manufacturing equipment. So, roller bit is a product requires high tech, advantage manufacture process and high-end manufacturing equipment.
