High Performance Diamond Bits for Rock Drilling¹

Preview:

Product Description Manufacturing ProcessThe manufacturing process of electroplated diamond drill bits mainly includes the following steps:Electroplating tank treatment: Diamond particles are plated layer by layer onto the drill bit body.Plastic mold shaping: Use plastic molds to ensure that the coating grows along the axis of the drill bit, and to ensure the inner and outer diameter dimensions and small grooves of the tire body.Repeated sanding and plating: Long term repeated sanding and plating form the working layer of the drill bit.Size:Φ75mm 94mm 113mm 133mm 153mm 171mm 200mm 250mm 275mm 325mmThread Type:Male Female ThreadApplication AreaElectroplated diamond drill bits are widely used in various applications that require high strength and wear resistance, especially in geological drilling, oil and gas drilling, and hydropower foundation drilling. Due to its manufacturing process being carried out at room temperature, it effectively ensures the thermal stability, strength, and wear resistance of diamond without damage, making this drill perform well in drilling operations on various hard materials.Performance CharacteristicsElectroplated diamond drill bits have the following performance characteristics:High Strength: By strengthening the matrix metal through electroplating technology, the deformation resistance and service life of the drill bit are improved.High Wear Resistance: The embedding of diamond particles enables the drill bit to perform well in hard materials and extend its service life.Strong adaptability: Suitable for various specialized drilling machines, especially performing well in drilling operations on hard materials such as glass, marble, and stone Hunan Yuanyu Exploration Technology Development Co., LtdOur company was formerly known as Hunan Zhuangyuan Geological Equipment Co., Ltd., which was affiliated with Hunan Provincial Institute of Geophysics and Geochemistry. The company was developed from the original 409 team mechanical repair workshop. In 1989, 409 Repair Factory was established. In 1992, Diamond Products Research Institute was founded. In 2003, Zhuangyuan (Group) Company was established, which includes Hunan Zhuangyuan Diamond Products Co., Ltd. and Hunan Zhuangyuan Geological Equipment Co., Ltd. In 2016, Hunan Yuanyu Exploration Technology Development Co., Ltd. was jointly established with Hunan Hongyu Water Resources and Hydropower (Group) Co., Ltd. It is a national high-tech enterprise specializing in the design, production, scientific research and development, and operation services of geological equipment such as drilling rigs, drilling tools, diamond drill bits, and centralized slurry injection equipment. In terms of emergency equipment, the company's developed "centralized slurry grouting system" has been shortlisted for the first batch of recommended emergency equipment procurement list in Hunan Province.In recent years, the company has also received various awards: the "Zhuangyuan" brand has been awarded the "Famous Trademark of Hunan Province" multiple times, and has been awarded the "Hunan Province Contract abiding and Creditworthy Unit" and "Hunan Province Integrity Construction Demonstration Unit" multiple times. And awarded the title of "National High tech Enterprise" in 2021.The company attaches great importance to technological innovation, and currently has more than 10 patents. It has maintained close ties with China University of Geosciences (Wuhan) and Central South University for a long time, and is now the industry university research base of China University of Geosciences (Wuhan). At the same time, the marine shallow sampling drilling rig jointly developed with the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences has received high praise from users.
